			<content:encoded><![CDATA[<!-- Start Shareaholic LikeButtonSetTop Automatic --><!-- End Shareaholic LikeButtonSetTop Automatic --><p><strong>Update: </strong>Once again I have updated this post with a few minor changes. Notably, I have added to graphs illustrating a separate <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/shift/" title="Glossary: Shift" onmouseover="tooltip.show('Refers to movements of curves in an economic diagram either inward or outward, up or down.');" onmouseout="tooltip.hide();">shift</a> in <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/supply/" title="Glossary: Supply" onmouseover="tooltip.show('A schedule or curve showing the direct relationship between the quantity of output firms produce in a particular period of time and the various prices of the good.');" onmouseout="tooltip.hide();">supply</a> and demand for loanable funds. Based on discussions with readers via email, it appears that my previous graph illustrating in one diagram the shifts of both supply and demand was confusing and could be considered double counting the effect of an increase in deficit spending. Thanks again to Professor Chuck Orvis for his valuable input.</p>

<p>Two markets for money, right? Yes&#8230; so do they show the same thing? <strong>NO! </strong>You must know the distinction between these two markets. First let&#8217;s talk about the Money<a title="Money Market" href="http://welkerswikinomics.com/blog/wp-content/uploads/2008/04/mm-and-lf_3.jpeg"><img src="http://welkerswikinomics.com/blog/wp-content/uploads/2008/04/mm-and-lf_3.jpeg" alt="Money Market" width="308" height="312" align="right" hspace="10" vspace="10" /></a> Market diagram.</p>
<p>This market refers to the Money Supply (M1 and M2). The Money Supply curve is vertical because it is determined by the Fed&#8217;s (or central bank&#8217;s) particular monetary policy. On the X axis is the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/quantity/" title="Glossary: Quantity" onmouseover="tooltip.show('This is the amount of output produced and consumed in a market determined by the supply and demand. As supply and demand change, the quantity in the market changes as well.');" onmouseout="tooltip.hide();">Quantity</a> of money supplied and demanded, and on the Y axis is the <strong><em>nominal interest rate</em></strong>. A tight monetary policy (selling of bonds by the Fed) will shift Money Supply in, raising the federal funds rate, and subsequently the interest rates commercial banks charge their best customers (prime interest rate)<em>.</em> On the other hand, an easy money policy (buying of bonds by the Fed) shifts Sm out, lowering the Federal Funds rate and thus the prime interest rate.</p>
<p>You should also know why a tight money policy is considered contractionary and why an easy money policy is considered expansionary monetary policy. Higher nominal interest rates resulting from tight money policy will discourage investment and consumption, contracting aggregate demand. On the other hand, an easy money policy will encourage more investment and consumption as nominal rates fall, expanding aggregate demand.</p>
<p>First watch this video lesson, which defines and introduces the money market diagram (skip ahead to 0:43 to hear the definition and explanation of the money market):</p>

<p><strong>Government deficit spending and the money market: </strong>Does an increase in government spending without a corresponding increase in taxes affect the money market? You may be inclined to say yes, since the Treasury must issue new bonds to finance deficit spending. After all, when the Fed sells bonds, money is taken out of circulation and held by the Fed, thus it&#8217;s no longer part of the money supply.</p>
<p>When the Treasury issues and sells new bonds, however, the money the public uses to buy the bonds is put back into circulation as the government spending is increased. Therefore, any leftward shift of the money supply curve caused by the buying of bonds by the public is offset by the injection of cash in the economy initiated the government&#8217;s fiscal stimulus package takes effect (be it a <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/taxes/" title="Glossary: Tax" onmouseover="tooltip.show('A payment made by an individual or a firm to the government, usually levied on income, property or the consumption of goods and services. Taxes are a leakage from the circular flow of income, but they provide government with the money they use to provide government services and public goods.');" onmouseout="tooltip.hide();">tax</a> rebate or an increase in spending). Therefore, money supply should remain stable when the government deficit spends.</p>
<p>However, since the money demand curve depends on the level of transactions going on in a nation&#8217;s economy in a particular period of time, an increase in government spending on infrastructure, defense, corporate subsidies, tax rebates or other fiscal policy initiatives will increase the demand for money, shifting the Dm curve rightward and driving up interest rates. The higher interest rates resulting from the greater demand for money reduces the quantity of private investment; in this way the crowding-out effect can be illustrated in the money market.</p>
<p align="left"><strong>Now to the loanable funds market.</strong> Loanable funds represents the money in commercial banks and lending institutions that is available to lend out to firms and households to finance expenditures (investment or consumption). The Y-axis represents the <strong><em><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/real-interest-rate/" title="Glossary: Real interest rate" onmouseover="tooltip.show('Represents the opportunity cost of borrowing money or the return earned on savings, adjusted for the rate of inflation in the economy. Equals the nominal interest rate minus the inflation rate.');" onmouseout="tooltip.hide();">real interest rate</a>; </em></strong>the loanable funds market therefore recognizes the relationships between real returns on savings and real price of borrowing with the public&#8217;s willingness to save and borrow.</p>
<p align="left">Watch this video for a clear explanation of the loanable funds market and how it can be used to illustrate the crowding-out effect (skip ahead to 3:18 for a definition and explanation of the loanable funds market):</p>
<p align="left"><p><a href="http://welkerswikinomics.com/blog/2012/05/08/loanable-funds-vs-money-market-whats-the-difference/"><em>Click here to view the embedded video.</em></a></p></p>
<p align="left">Since an increase in the real interest rate makes households and firms want to place more money in the bank (and more money in the bank means more money to loan out), <em><strong>there is a direct relationship between real interest rate and Supply of Loanable Funds</strong>.</em> On the other hand, since at lower real interest rates households and firms will be less inclined to save and more inclined to borrow and spend, <em><strong>the Demand for loanable funds reflects an inverse relationship. </strong></em>At higher interest rates, households prefer to delay their spending and put their money in savings, since the opportunity cost of spending now rises with the real interest rate.</p>
<p><strong>Government deficit spending and the loanable funds market: </strong>We learned above that only the Fed can shift the money supply curve, but what factors can affect the Supply and Demand curves for loanable funds? Here&#8217;s a few key points to know about the loanable funds market.<a href="http://welkerswikinomics.com/blog/wp-content/uploads/2008/06/crowding-out-in-lf-market_1.jpg"><img class="alignright alignnone size-medium wp-image-502" style="margin: 15px; float: right;" title="crowding-out-in-lf-market_1" src="http://welkerswikinomics.com/blog/wp-content/uploads/2008/06/crowding-out-in-lf-market_1.jpg" alt="" width="367" height="426" /></a></p>
<ul>
<li>When the government deficit spends (G&gt;tax revenue), it must borrow from the public by issuing bonds.</li>
<li>The Treasury issues new bonds, which shifts the supply of bonds out, lowering their prices and raising the interest rates on bonds.</li>
<li>In response to higher interest rates on bonds, investors will transfer their money out of banks and other lending institutions and into the bond market. Banks will also lend out fewer of their excess reserves, and put some of those reserves into the bond market as well, where it is secure and now earns relatively higher interest.</li>
<li>As households, firms and banks buy the newly issued Treasury securities (which represents the public&#8217;s lending to the government), the supply of private funds available for lending to households and firms shifts in. With fewer funds for private lending banks must raise their interest rates, leading to a movement along the demand curve for loanable funds.</li>
<li>This causes <em>crowding out</em> of private investment.</li>
</ul>
<p>Another, simpler way to understand the effect of government deficit spending on real interest rates is to look at it from the demand side.<a href="http://welkerswikinomics.com/blog/wp-content/uploads/2008/06/crowding-out-in-lf-market_2.jpg"><img class="alignright alignnone size-medium wp-image-503" style="float: right;" title="crowding-out-in-lf-market_2" src="http://welkerswikinomics.com/blog/wp-content/uploads/2008/06/crowding-out-in-lf-market_2.jpg" alt="" width="385" height="447" /></a></p>
<ul>
<li>Deficit spending by the government requires the government to borrow from the public, increasing the demand for loanable funds. In essence, the government becomes a borrower in the country&#8217;s financial sector, demanding new funds for investment, driving up real interest rates.</li>
<li>Increased demand from the government pushes interest rates up, causing banks to supply a greater quanity of funds for lending. The private, however, now has fewer funds available to borrow as the government soaks up some of the funds that previously would have gone to private borrowers.</li>
<li>This leads to <a href="http://www.econclassroom.com/?glossary=crowding-out-effect" target="_blank"><strong>the crowding out of private investment</strong></a>, in which private borrowers face higher real interest rates due to increased deficit spending by the government.</li>
</ul>
<p>What could shift the supply of loanable funds to the <em>right?</em> Easy, anything that <strong>increases savings</strong> by households and firms, known as the <em>determinants of consumption and saving.</em> These include <strong>increases in wealth, expectations of future income and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/price-level/" title="Glossary: Price level" onmouseover="tooltip.show('A macroeconomic term referring to the average price of the goods produced by the various industries present in a nation's economy. Found on the vertical axis of an aggregate demand / aggregate supply diagram.');" onmouseout="tooltip.hide();"><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/price/" title="Glossary: Price" onmouseover="tooltip.show('This is the amount paid for a good determined by the supply and demand for the good in the market. Price rises and falls as demand and supply rise and fall.');" onmouseout="tooltip.hide();">price</a> levels</a>, and lower taxes. </strong>If savings increases, supply of loanable funds shifts outward, increasing the reserves in banks, lowering real <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/interest-rate/" title="Glossary: Interest rate" onmouseover="tooltip.show('The opportunity cost of money. Either the cost of borrowing money or the cost of spending money. What would be given up by not saving money.');" onmouseout="tooltip.hide();"><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/interest/" title="Glossary: Interest" onmouseover="tooltip.show('The payment for capital in the resource market. Firms pay interest on the money they borrow to acquire capital equipment (technology). Households receive interest for providing their savings to banks, who make the loans to the firms paying interest.');" onmouseout="tooltip.hide();">interest</a> rates</a>, encouraging firms to undertake new <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/investment/" title="Glossary: Investment" onmouseover="tooltip.show('A component of aggregate demand, it includes all spending on capital equipment, inventories, and technology by firms. This does not include financial investment, which is the purchase of financial assets (stocks and bonds), not included in GDP because they are only purely financial investments.');" onmouseout="tooltip.hide();">investments</a>. This is why many economists say that &#8220;savings is investment&#8221;. What they mean is increased increased savings leads to an increase in the supply of loanable funds, which leads to lower interest rates and increased investment.</p>
<p>On the other hand, an increase in <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/demand/" title="Glossary: Demand" onmouseover="tooltip.show('A schedule or curve showing the quantities of a particular good demanded at a range of price in a particular period of time.');" onmouseout="tooltip.hide();">demand</a> for investment funds by firms will shift demand for loanable funds out, driving up real interest rates. The <span style="text-decoration: underline;"><em><a href="http://welkerswikinomics.wetpaint.com/page/The+Interest+Rate+-+Investment+Relationship" target="_blank">determinants of investment</a></em></span> include business taxes, technological change, <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/expectations/" title="Glossary: Expectations" onmouseover="tooltip.show('Refers to the assumptions individual households and firms hold about future economic conditions. Current decisions are often made based on expectations of the future.');" onmouseout="tooltip.hide();">expectations</a> of future business opportunities, and so on (follow link to our wiki page on Investment).</p>
<p>It is important to be able to distinguish between the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/3391/" title="Glossary: Money market" onmouseover="tooltip.show('The market where the supply of money is set by the central bank, includes the downward sloping money demand curve and a vertical money supply curve.

			<content:encoded><![CDATA[<!-- Start Shareaholic LikeButtonSetTop Automatic --><!-- End Shareaholic LikeButtonSetTop Automatic --><p>At this point in the course, you may find yourself asking, &#8220;what is the difference between <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/microeconomics/" title="Glossary: Microeconomics" onmouseover="tooltip.show('The study of the interactions between consumers and producers in markets for individual products.');" onmouseout="tooltip.hide();">microeconomics</a> and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/macroeconomics/" title="Glossary: Macroeconomics" onmouseover="tooltip.show('The study of entire nations’ economies and the interactions between households, firms, government and foreigners.');" onmouseout="tooltip.hide();">macroeconomics</a>?&#8221; It has been a long time since we first defined these terms at the beginning of the course. The purpose of this post is to introduce some basic Macro concepts help clear up the confusing and not so obvious differences between these two areas of economics.</p>
<p>A teacher of mine once explained the difference between micro and macro using the example of a tree and a forest. Microeconomics is the like the study of an individual tree, standing in a thick forest of thousands of individual trees of different species. A microeconomist might study the systems that make an individual tree function efficiently, providing it with the sustanence it needs to thrive in the forest. A macroeconomist, however, will take a broader look at the forest as a whole, and observe how the thousands of trees work together in conjunction with the sun, the soil, the oxygen, nitrogen, and H2O in the environment that make the entire forest function efficiently as one giant organism.</p>
<p>Put literally, the tree is like an individual <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/market/" title="Glossary: Market" onmouseover="tooltip.show('A place where buyers and sellers meat to engage in mutual trade. Prices are set by the interaction of demand and supply in a market.');" onmouseout="tooltip.hide();">market</a>. This may be a product market like the market for apples, or a <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/resource-market/" title="Glossary: Resource market" onmouseover="tooltip.show('The market in a nation's circular flow in which households provide firms with the factors of production (land, labor and capital) in exchange for money incomes (rent, wages and interest). Firms are the buyers, households are the sellers in the resource market.');" onmouseout="tooltip.hide();">resource market</a> like the market for apple pickers. Microeconomists will study the characteristics of an individual market: the firms and their costs, tradeoffs, challenges presented by competition or the inefficiencies that result from a lack thereof, and the buyers in the market: the alternatives and trade-offs they face, the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/utility/" title="Glossary: Utility" onmouseover="tooltip.show('"Happiness" in economics. Individuals in market economies tend to make decisions to maximize their own happiness given their limited incomes and time. To maximize his happiness, a consumer should consume the quantity of two or more goods at which the last dollar spent on each good provided the same amount of happiness as the last dollar spent on each other good consumed.');" onmouseout="tooltip.hide();">utility</a> they receive and the decisions they make based on these factors. Microeconomics concerns itself not with the health of the economy <em>as a whole</em>, rather with the individual markets, firms, and consumers within the economy, and the challenges of efficiency and resource allocation faced by those markets.</p>
<p>Macroeconomics, on the other hand, studies the health of the economy <em>as a whole</em>. Macro deals with <em>aggregates,</em> or &#8220;collections of specific economic units treated as if they were one. &#8221; For example, instead of studying <em>price of a product</em>, as a microeconomist would, a macroeconomist looks at <em>the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/price-level/" title="Glossary: Price level" onmouseover="tooltip.show('A macroeconomic term referring to the average price of the goods produced by the various industries present in a nation's economy.

Price rises and falls as demand and supply rise and fall.');" onmouseout="tooltip.hide();">price</a> level</a></em> in the whole economy. Whereas a microeconomist looks at <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/supply/" title="Glossary: Supply" onmouseover="tooltip.show('A schedule or curve showing the direct relationship between the quantity of output firms produce in a particular period of time and the various prices of the good.');" onmouseout="tooltip.hide();">supply</a> and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/demand/" title="Glossary: Demand" onmouseover="tooltip.show('A schedule or curve showing the quantities of a particular good demanded at a range of price in a particular period of time.');" onmouseout="tooltip.hide();">demand</a> in a particular market, a macroeconomist studies <em><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/aggregate-supply/" title="Glossary: Aggregate Supply" onmouseover="tooltip.show('The total amount of goods and services that all the firms in all the industries in a country will produce at various price levels in a given period of time.');" onmouseout="tooltip.hide();">aggregate supply</a> and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/aggregate-demand/" title="Glossary: Aggregate Demand" onmouseover="tooltip.show('A schedule or curve which shows the total demand for the goods and services of a nation at a range of price levels and at a given period of time.');" onmouseout="tooltip.hide();">aggregate demand</a>, </em>assessing the collective <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/marginal/" title="Glossary: Marginal" onmouseover="tooltip.show('Means "additional".

As supply and demand change, the quantity in the market changes as well.');" onmouseout="tooltip.hide();">quantity</a> supplied, </em>the macroeconomist examines <em>aggregate output, or gross domestic product</em>. Instead of underallocation and overallocation of resources, the macroeconomists concerns himself with <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/unemployment/" title="Glossary: Unemployment" onmouseover="tooltip.show('The state of an individual who is of working age, actively seeking work, but unable to find a job.');" onmouseout="tooltip.hide();">unemployment</a> and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/inflation/" title="Glossary: Inflation" onmouseover="tooltip.show('A rise in the average level of prices in the economy over time (percentage change in the CPI).');" onmouseout="tooltip.hide();">inflation</a>.</p>
<p>When it comes to the role of government, macroeconomics has a lot more to say about the role a central government should play in managing the <em>economy as a whole</em>. One major theme of microeconomics is that competitive markets, when left alone by government, tend to achieve efficient allocations of resources. You&#8217;ll find that in Macro, however, the government often plays a central part in stimulating and slowing down the level of economic activity in the economy, using tools such as <em>fiscal and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/monetary-policy/" title="Glossary: Monetary policy" onmouseover="tooltip.show('The central bank’s manipulation of the supply of money aimed at raising or lowering interest rates to stimulate or contract the level of aggregate demand to promote the macroeconomic objectives of price level stability and full employment.');" onmouseout="tooltip.hide();">monetary policy</a>.</em></p>
<p>Also in macroeconomics, we&#8217;ll study in more depth the role that <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/comparative-advantage/" title="Glossary: Comparative advantage" onmouseover="tooltip.show('When an individual, a firm or a nation is able to produce a particular product at a lower opportunity cost than another individual, firm or nation. Forms the basis on which nations trade with one another.');" onmouseout="tooltip.hide();">comparative advantage</a> plays in the economic exchanges that take place between nations. International trade also involves the exchange of foreign currencies, which we&#8217;ll try to understand by studying <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/exchange-rate/" title="Glossary: Exchange rate" onmouseover="tooltip.show('The price of one currency in terms expressed in terms of another currency, determined in the forex market.');" onmouseout="tooltip.hide();">exchange rates</a> and the role that governments play in manipulating and controlling the values of their currencies.</p>
<p>Macroeconomics will prove to be particularly relevant to the events going on in the recent turbulent global economy.  If have listened to the news lately you&#8217;ve heard world leaders, political pundits and commentators from all political and economic leanings use words like &#8220;bailout&#8221;, &#8220;fiscal stimulus&#8221;, &#8220;monetary easing&#8221;, &#8220;deficit spending&#8221; and others; all concepts having to do with macroeconomics. In the next few months, you will begin to see the forest through the trees as we take on the exciting  and challenging field of macroeconomics.</p>

			<content:encoded><![CDATA[<!-- Start Shareaholic LikeButtonSetTop Automatic --><!-- End Shareaholic LikeButtonSetTop Automatic --><p>In my original &#8220;<em>Golden Balls&#8221; </em>blog post (see below), written almost three years ago after I saw a clip of the finale in an episode of the British game show, <em>Golden Balls, </em>I analyzed the actions of Sarah and Steve, who  had to decide whether they would split or steal a jackpot of 100,000 British pounds. The contestants had one minute to try to convince one another that they would split the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/money/" title="Glossary: Money" onmouseover="tooltip.show('Any object that can be used to facilitate the exchange of goods and services in a market.');" onmouseout="tooltip.hide();">money</a>; but when it came down to it Sarah stole and Steve split, meaning Sarah got to keep the whole jackpot and Steve went home with nothing.</p>
<p>In that original post, I proposed that Steve&#8217;s best chances for going home with any money would have been <em>&#8220;for him to use the one minute of discussion time to convince Sarah that he would choose SPLIT, yet be willing to go home with something LESS THAN $50,000 and accept that Sarah was going to choose STEAL. He could have threatened to chose steal if she did not agree to share her winnings with him to some extent.&#8221;</em></p>
<p>In a recent episode of the same game show, a contestant followed a similar strategy to that I suggested Steve should have taken. Watch the clip below, from a February 2012 episode of <em>Golden Balls</em>.<br />
<iframe src="http://www.youtube.com/embed/S0qjK3TWZE8" frameborder="0" width="480" height="360"></iframe></p>
<p>In this episode, Nick immediately takes control of the negotiations by insisting that he is going to <em>steal</em>, which is a very unorthodox approach to this game, in which the traditional strategy is to try and convince your opponent that you are going to <em>split</em>. By establishing a credible threat to <em>steal</em>, Nick puts all the pressure on Ibraham to decide only one of two things:</p>
<ol>
<li>Does Ibraham trust that Nick will split the money with him after he has stolen the full jackpot, and</li>
<li>Would Ibraham rather both of them go home without any money at all than Nick win the jackpot and possibly not split it with him later on?</li>
</ol>
<div>Nick&#8217;s strategy is brilliant. By the end of the negotiation, Nick has convinced Ibraham 100% that he is going to steal the money. Ibraham may only have had a confidence level of 50% that Nick was honest about splitting the money with him after the show, but with a 50% confidence level, Ibrahim&#8217;s possible payoffs are:</div>
<div>
<ul>
<li>Choose steal and go home with nothing.</li>
<li>Choose split and have a 50/50 chance of going home with half the jackpot (based on his level of confidence in Nick&#8217;s promise to split the money after the show).</li>
</ul>
<div>In other words, with a jackpot of 14,000 pounds, the payoffs for Ibrahim became:</div>
<div>
<ul>
<li>If he splits: 0 pounds or 0.5(14,000) = 7,000 pounds</li>
<li>If he steals: 0 pounds or 0 pounds (assuming his confidence level in Nick&#8217;s intention to steal is 100%).</li>
</ul>
</div>
<div>Clearly Ibraham now has a dominant strategy: to split. In the typical version of this game, a player&#8217;s dominant strategy is always to <em>steal</em> (as explained below), since the possible payoffs are:</div>
<div>
<ul>
<li>If you split: 0 pounds or half the jackpot</li>
<li>If you steal: 0 pounds or the whole jackpot.</li>
</ul>
</div>
<div>But because Nick has convinced his opponent that he will steal, and then split the winnings, Ibraham&#8217;s dominant strategy shifted to split, since the possible payoffs have changed. Ultimately, Ibraham does what is most rational given his confidence in Nick&#8217;s threat to steal, and that is to split. Ibraham then chooses split (as he should), but then to everyone&#8217;s surprise, Nick chooses <em>split</em>, not <em>steal</em> as he had threatened to do throughout the negotiation. This a surprising twist, since from Nick&#8217;s perspective <em>stealing</em> is clearly now a dominant strategy! Nick had convinved Ibraham to split, which means Nick faced a greater payoff by stealing. But by splitting, Nick shows that he had intended to split all along, but first needed to convince Ibraham otherwise to establish splitting as Ibraham&#8217;s dominant strategy.</div>
</div>
<div>-</div>
<div>What a thrilling game! I won&#8217;t even bother getting into how this relates to economics today, I&#8217;m still shaking with excitement over the outcome!</div>
<div>-</div>
<div><strong>Original Golden Balls post:</strong></div>
<div>-</div>
<div><a href="http://cheeptalk.wordpress.com/2009/04/08/teaching-the-prisoners-dilemma-will-never-be-the-same-again/">Teaching the Prisoners’ Dilemma Will Never Be the Same Again « Cheap Talk</a></div>
<p>Rarely does such a perfect illustration of the Prisoner&#8217;s Dilemma come along for Econ teachers to use in their classroom:</p>
<div class="youtube-video"><object width="425" height="355" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="wmode" value="transparent" /><param name="src" value="http://www.youtube.com/v/p3Uos2fzIJ0" /><embed width="425" height="355" type="application/x-shockwave-flash" src="http://www.youtube.com/v/p3Uos2fzIJ0" wmode="transparent" /></object></div>
<p>The payoffs are clear:<br />
<img style="max-width: 800px;" src="http://welkerswikinomics.com/blog/wp-content/uploads/2009/04/prisoners-dilemma-11.jpeg" alt="" /><br />
Each player has a <em>weakly dominant strategy, </em>which is to choose to steal.<em> </em>By choosing to steal, the player has a chance at maximizing his own payoff, but will do no worse than he would if his opponent also chooses to steal and at least will have the satisfaction of thwarting his opponent&#8217;s attempt to steal the money.</p>
<p>There are three Nash equilibria in the game, which are outcomes at which a player can not do better on his or her own by changing his or her strategy. The outcome Steve was hoping for by chosing &#8220;split&#8221; (50/50) was not a Nash <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/equilibrium/" title="Glossary: Equilibrium" onmouseover="tooltip.show('Refers to the price and quantity determined in a market when the supply equals the demand. At equilibrium there are no surpluses or shortages of the product; at the equilibrium price the quantity supplied equals the quantity demanded.');" onmouseout="tooltip.hide();">equilibrium</a> because Sarah knows she can do better if she chooses steal when Steve chooses split. Steve doomed himself by choosing split because he should know that Sarah&#8217;s dominant strategy is to choose steal. However, Sarah would also have doomed herself by choosing split because she should assume that Steve would also chose steal since steal is a dominant strategy for him too.</p>
<p>John Nash, who pioneered the field of Game Theory, assumed that humans were coldly rational, self-interested, deceptive creatures that would not hesitate to stab one another in the back to get what was best for themselves. His theory of human behavior is only partially proven correct in this game, in which Steve is shown to be the sucker and Sarah the coldly rational self-interested player. The best chance for Steve to go home with any money would have been for him to use the one minute of discussion time to convince Sarah that he would choose SPLIT, yet be willing to go home with something LESS THAN $50,000 and accept that Sarah was going to choose STEAL. He could have <em>threatened</em> to chose steal if she did not agree to share her winnings with him to some extent. Then again, any promise Sarah makes she could later break, thus further empowering the players to choose steal.</p>
<p><strong>Discussion questions:<br />
</strong></p>
<ol>
<li>What in the world is going on here? Why did Sarah choose steal rather than collaborate with Steve and share the $100,000?</li>
<li>Was Steve totally wrong to choose split? What would you have done in his situation?</li>
<li>How do the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/choice/" title="Glossary: Choice" onmouseover="tooltip.show('In economics, decisions must be made between the various alternative uses for society's scarce resources. Every choice involves an opportunity cost.');" onmouseout="tooltip.hide();">choices</a> faced by Steve and Sarah relate to the choices faced by firms in oligopolitic <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/market/" title="Glossary: Market" onmouseover="tooltip.show('A place where buyers and sellers meat to engage in mutual trade.

Now that you&#8217;ve seen this video, can you explain why collusive agreements between oligopolists often fall apart?

<p>One of the oldest arguments against stimulus, however, is that which says when a government borrows money to pay for such a policy, it can lead to a decrease in private investment and a decrease in future demand as the higher level of debt must be paid back in the future. Short-term stimulus, therefore, is counter-productive since any debts incurred must be paid back in the future, leading to lower levels of spending and therefore higher unemployment sometime down the road.</p>
<p>The crowding-out effect of fiscal policy is explained in detail in the following video from <em><a href="http://www.econclassroom.com" target="_blank">The Economics Classroom</a></em>:</p>
<p><iframe src="http://www.youtube.com/embed/mwjvutjDhOw" frameborder="0" width="600" height="335"></iframe></p>
<p>A recent study by two leading American economists provides an argument against this view of the crowding-out effect of fiscal policy:</p>
<blockquote><p>In a new paper* written with Brad DeLong of the University of California, Berkeley, Mr Summers, now at Harvard after a stint as Barack Obama’s chief economic adviser, says that in the odd circumstances America faces today temporary stimulus “may actually be self-financing”&#8230;</p>
<p>Mr DeLong and Mr Summers are careful to say stimulus almost never pays for itself. When the economy is near full employment, deficits crowd out private spending and investment. In a <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/recession/" title="Glossary: Recession" onmouseover="tooltip.show('A decrease in the total output of goods and services in a nation between two periods of time. Could be caused by a decrease in aggregate demand or in aggregate supply.');" onmouseout="tooltip.hide();">recession</a> the central bank will respond to fiscal stimulus by keeping interest rates higher than they would otherwise be. Both effects mean that in normal times the fiscal “multiplier”—the amount by which output rises for each dollar of government spending or <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/taxes/" title="Glossary: Tax" onmouseover="tooltip.show('A payment made by an individual or a firm to the government, usually levied on income, property or the consumption of goods and services. Taxes are a leakage from the circular flow of income, but they provide government with the money they use to provide government services and public goods.');" onmouseout="tooltip.hide();">tax</a> cuts—is probably close to zero.</p></blockquote>
<p>The “multiplier” referred to here is what economist refer to as the Keynesian <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/spending-multiplier/" title="Glossary: Spending multiplier" onmouseover="tooltip.show('1/(1-MPC), or 1/MPS, where MPC is the marginal propensity to consume and MPS is the marginal propensity to save. It tells you how much total spending an initial injection of spending in the economy will generate. For example, if the MPC = .8 and the government spends 0 million, then the total increase in spending in the economy = 0 x 5 = 0 million.');" onmouseout="tooltip.hide();">spending multiplier</a>, which is based on the theory that any increase in spending in an economy (say, through a new government spending package), will lead to further increases in spending (as households feel more confident and firms start to hire workers again), therefore the final change in <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/national-income/" title="Glossary: National income" onmouseover="tooltip.show('Another term for the GDP of a nation. Measures the total income earned by households in the resources market for their provision of labor, land, capital and entrepreneurship to the nation's producers.');" onmouseout="tooltip.hide();">national <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/income/" title="Glossary: Income" onmouseover="tooltip.show('The money earned by households for providing their resources (land, labor and capital) to firms in the resource market. Incomes include wages, interest, rent and profit.');" onmouseout="tooltip.hide();">income</a></a> resulting from a <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/fiscal-policy/" title="Glossary: Fiscal policy" onmouseover="tooltip.show('Fiscal policy: Changes in government spending and tax collections implemented by government with the aim of either increasing or decreasing aggregate demand to achieve the macroeconomic objectives of full employment and price level stability.');" onmouseout="tooltip.hide();">fiscal policy</a> will be greater than the initial change in spending itself. This <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/multiplier-effect/" title="Glossary: Multiplier effect" onmouseover="tooltip.show('The theory that a particular increase in private or government spending (C, I, G, or Xn) in an economy will lead to a larger overall increase in GDP than the initial change in spending, due to the fact that the increase in incomes that result will lead to further increases in private spending throughout the economy. The size of the multiplier effect depends on the spending multiplier.');" onmouseout="tooltip.hide();">multiplier effect</a> has formed the basis of the argument for expansionary fiscal policy since Keynes articulated it in the 1930’s.</p>
<p>The multiplier effect is explained in detail in the following video lesson:</p>
<p><iframe src="http://www.youtube.com/embed/IWGt-CSnXc8" frameborder="0" width="600" height="360"></iframe></p>
<p>If the multiplier is ZERO, there is no point in engaging in expansionary fiscal policies since there will be no additional increase in output as a government goes into debt to pay for a tax cut or an increase in spending. In the US today, argue Summers and Delong, the multiplier is probably not zero. Additionally, crowding-out is unlikely to occur.</p>
<blockquote><p>Such constraints are not present now (meaning in the United States in 2012). <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/investment/" title="Glossary: Investment" onmouseover="tooltip.show('A component of aggregate demand, it includes all spending on capital equipment, inventories, and technology by firms. This does not include financial investment, which is the purchase of financial assets (stocks and bonds), not included in GDP because they are only purely financial investments.');" onmouseout="tooltip.hide();">Investment</a> and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/demand/" title="Glossary: Demand" onmouseover="tooltip.show('A schedule or curve showing the quantities of a particular good demanded at a range of price in a particular period of time.');" onmouseout="tooltip.hide();">demand</a> are deeply depressed and the central bank, having cut <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/interest-rate/" title="Glossary: Interest rate" onmouseover="tooltip.show('The opportunity cost of money. Either the cost of borrowing money or the cost of spending money. What would be given up by not saving money.');" onmouseout="tooltip.hide();"><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/interest/" title="Glossary: Interest" onmouseover="tooltip.show('The payment for capital in the resource market. Firms pay interest on the money they borrow to acquire capital equipment (technology). Households receive interest for providing their savings to banks, who make the loans to the firms paying interest.');" onmouseout="tooltip.hide();">interest</a> rates</a> to zero, is not about to raise them. The multiplier is higher than usual as a result&#8230;</p></blockquote>
<p>Basically, Summers and Delong are trying to argue that the US government should engage in another round of fiscal stimulus, to offer additional support to the economy beyond 2009’s “Obama stimulus” and the current bill being debated in Washington, the American Jobs Act, a $470 billion tax cut and spending bill aimed at keeping unemployment from rising in America.</p>
<p>On one side of this debate are those like Summers and Delong who argue fiscal stimulus can pay for itself since it can leads to a larger increase in GDP than the increase in the government’s <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/budget-deficit-2/" title="Glossary: Budget deficit" onmouseover="tooltip.show('Budget deficit: When a government spends more than it collects in tax revenues.');" onmouseout="tooltip.hide();"><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/budget-deficit/" title="Glossary: Budget deficit" onmouseover="tooltip.show('When a government spends more than it collects in tax revenues.');" onmouseout="tooltip.hide();">budget deficit</a></a> needed to finance the stimulus. On the other side are those “deficit hawks” who believe that any increase in government debt will lead to a fall in current and future <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/aggregate-demand/" title="Glossary: Aggregate Demand" onmouseover="tooltip.show('A schedule or curve which shows the total demand for the goods and services of a nation at a range of price levels and at a given period of time.');" onmouseout="tooltip.hide();">aggregate demand</a> from the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/private-sector/" title="Glossary: Private sector" onmouseover="tooltip.show('Refers to the activities undertaken by the private households and firms in an economy. "Private sector spending" includes household consumption and investment by private, non-government-owned firms.');" onmouseout="tooltip.hide();">private sector</a>, and therefore expansionary fiscal policies will just be crowded out by declining private sector spending.</p>
<p>By understanding the circumstances in which crowding-out is most likely and unlikely to occur, we should be able to make a more informed decision about future fiscal policy decisions. As these two economists argue, and as I have tried to present in this post and in a previous post <em><a href="http://welkerswikinomics.com/blog/2011/11/18/a-closer-look-at-the-crowding-out-effect/" target="_blank">A Closer Look at the Crowding-out Effect</a></em>, today’s economy provides policy-makers with the perfect opportunity to stimulate aggregate demand by increasing the deficit and providing the US economy with the boost in demand it needs to get America back to <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/full-employment/" title="Glossary: Full employment" onmouseover="tooltip.show('When an economy is producing at a level of output at which almost all the nation’s resources are employed. The unemployment rate at this level of output equals the natural rate of unemployment, and includes only frictional and structural unemployment.');" onmouseout="tooltip.hide();">full employment</a>.</p>
<p><strong>Discussion Questions:</strong></p>
<ol>
<li>Why is crowding-out more likely to occur when an economy is already producing at or near its full employment level of output than when an economy is in recession?</li>
<li>How are the theories of <em>crowding-out</em> and the <em>multiplier effect</em> used to argue for two different sides in the debate over the use of expansionary fiscal policy?</li>
<li>Why might a government deficit, paid for with borrowed <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/money/" title="Glossary: Money" onmouseover="tooltip.show('Any object that can be used to facilitate the exchange of goods and services in a market.');" onmouseout="tooltip.hide();">money</a>, lead to an expectation of a future increase in taxes?</li>
<li>Do you believe the government should take action during periods of economic hardship, or should it just get out of the way and let the economy &#8220;correct itself&#8221;?</li>

Price rises and falls as demand and supply rise and fall.');" onmouseout="tooltip.hide();">prices</a>, change its output, expand into a new market, offer new <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/services/" title="Glossary: Services" onmouseover="tooltip.show('The non-physical output of firms meant for consumption in a product market. Services are "non-tangible" goods, such as taxi rides, accounting, doctor visits, teaching, and other products that can be bought and sold, but not physically consumed.');" onmouseout="tooltip.hide();">services</a>, or adverstise, will have powerful and consequential effects on the profitability of its competitors. For this reason, firms in oligopolistic markets are always considering the behavior of their competitors when making their own economic decisions.</p>
<p>To understand the behavior of non-collusive oligopolists (<em>non-collusive meaning a few firms that do NOT cooperate on output and price</em>), economists have employed a mathematical tool called Game Theory. The assumption is that large firms in competition will behave similarly to individual players in a game such as poker. Firms, which are the “players” will make “moves” (referring to economic decisions such as whether or not to advertise, whether to offer discounts or certain services, make particular changes to their products, charge a high or low price, or any other of a number of economic actions) based on the predicted behavior of their competitors.</p>
<p>If a large firm competing with other large firms understands the various “payoffs” (referring to the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/profit/" title="Glossary: Profit" onmouseover="tooltip.show('The payment to the entrepreneur in the resource market. A business owner expects to earn a "normal" level of profit, otherwise it will not be worth his while to remain in a market. In this regard, profit is a cost of production, because if a minimum profit is not earned a firm will shut down.');" onmouseout="tooltip.hide();">profits</a> or losses that will result from a particular economic decision made by itself and its competitors) then it will be better able to make a rational, profit-maximizing (or loss minimizing) decision based on the likely actions of its competitors. The outcome of such a situation, or game, can be predicted using payoff matrixes. Below is an illustration of a game between two coffee shops competing in a small town.</p>
<p><a href="http://welkerswikinomics.com/blog/wp-content/uploads/2009/02/game-theory-1.jpeg"><img class="alignnone" src="http://welkerswikinomics.com/blog/wp-content/uploads/2009/02/game-theory-1.jpeg" alt="" width="554" height="368" /></a></p>
<p>In the game above, both SF Coffee and Starbuck have what is called a <em>dominant strategy.</em> Regardless of what its competitor does, both companies would maximize their outcome by advertising. If SF coffee were to <em>not advertise, </em>Starbucks will earn more profits ($20 vs $10) by advertising. If SF coffee were to <em>advertise, </em>Starbucks will earn more profits ($12 vs $10) by advertising. The payoffs are the same given both options for SF Coffee. Since both firms will do best by advertising given the behavior of its competitor, both firms will advertise. Clearly, the total profits earned are less when both firms advertise than if they both did NOT advertise, but such an outcome is <em>unstable </em>because the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/incentive/" title="Glossary: Incentive" onmouseover="tooltip.show('Refers to the motivation an individual has to undertake a particular action.');" onmouseout="tooltip.hide();">incentive</a> for both firms would be to <em>advertise. </em> We say that <em>advertise/advertise </em> is a <em><strong>&#8220;Nash <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/equilibrium/" title="Glossary: Equilibrium" onmouseover="tooltip.show('Refers to the price and quantity determined in a market when the supply equals the demand. At equilibrium there are no surpluses or shortages of the product; at the equilibrium price the quantity supplied equals the quantity demanded.');" onmouseout="tooltip.hide();">Equilibrium</a>&#8221;</strong></em> since neither firm has an incentive to vary its strategy at this point, since less profits will be earned by the firm that stops advertising.</p>
<p>As illustrated above, the tools of Game Theory, including the “payoff matrix”, can prove helpful to firms deciding how to respond to particular actions by their competitors in oligopolistic markets. Of course, in the real world there are often more than two firms in competition in a particular market, and the decisions that they must make include more than simply to advertise or not. Much more complicated, multi-player games with several possible “moves” have also been developed and used to help make tough economic decisions a little easier in the world of competition.</p>
<p>Game theory as a mathematical tool can be applied in realms beyond <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/oligopoly/" title="Glossary: Oligopoly" onmouseover="tooltip.show('A market in which a relatively small number of firms compete with one another in a strategic manner. Characterized by a strong interdependence between the small number of firms. Barriers to entry are high and firms are hesitant to change their prices due to the fact that price wars may result when prices are lowered, and significant market share can be lost if prices are raised. Such markets tend to be highly inefficient due to the lack of competition.');" onmouseout="tooltip.hide();">oligopoly</a> behavior in Economics.  In each of the videos below, game theory can be applied to predict the behavior of different &#8220;players&#8221;. None of the videos portray a Microeconomic scenario like the one above, but in each case a payoff matrix can be created and behavior can be predicted based on an analysis of the incentives given the player&#8217;s possible behaviors.</p>

			<content:encoded><![CDATA[<!-- Start Shareaholic LikeButtonSetTop Automatic --><!-- End Shareaholic LikeButtonSetTop Automatic --><p><a href="http://www.newsobserver.com/2012/02/27/1887298/gas-pushes-up-cost-of-delivery.html">Gas pushes up cost for Triangle delivery restaurants &#8211; Economy &#8211; NewsObserver.com</a></p>
<p>Read the article below and answer the discussion questions that follow:</p>
<blockquote><p>Do you love the convenience of having your pepperoni pizza or egg foo young delivered right to your door?</p>
<p>If gas prices continue to rise in the next few months, it might cost you more for the privilege depending on where you order.</p>
<p>Triangle-area delivery restaurants worry about the impact higher gas prices could have on their businesses. It&#8217;s a concern that is felt among these restaurants nationwide.</p>
<p>On Sunday, the average price for regular unleaded gas in North Carolina was about $3.71, according to AAA. The website raleighgasprices.com listed prices as low at $3.54 in Fuquay-Varina and as high as $3.89 in Cary.</p>
<p>HotBox Pizza on Hillsborough Street charges $2 for a delivery to help offset the costs of gas for its drivers. While owner James McCaskill said there are no imminent plans to raise that fee, he does worry that it could cost more to get food shipments in.</p>
<p>&#8220;For us to deliver the pizza, there&#8217;s a cost,&#8221; McCaskill said. &#8220;We have to pay for our drivers and the wear and tear on their car and essentially to help pay for the gas they use to deliver the pizzas.&#8221;</p>
<p>Bruno Rodriguez, owner of Amante Gourmet Pizza in Durham, said back in 2008 when gas hovered around $4 a gallon, the effects weren&#8217;t so bad because the hike was short lived. But he&#8217;s more worried about it in 2012 during a time when roughly 60 percent of his orders are for delivery.</p>
<p>&#8220;I think we&#8217;re coming slowly out of a recession, but I think with gas prices around $4, I think it&#8217;s going to be longer lived so that definitely will have an impact,&#8221; he said. &#8220;People will tend to not order many deliveries.&#8221;</p>
<p>Rodriguez said Amante charges $1.40 for deliveries in the Bull City, and he probably spends about $40 or $50 a week on gas for deliveries. Fortunately for him, he has a small Toyota, but he isn&#8217;t ruling out raising his delivery charge 20 or 30 cents if things get worse.</p>
<p>Shanghai Express, across from N.C. State University on Hillsborough Street, serves primarily college students.</p>
<p>&#8220;The economy is no good, so business definitely goes down,&#8221; said manager Jinlong Wang, who estimates about half of his orders are deliveries. &#8220;Their parents pay their tuition. But when economy no good, parents have no money and (students) have no money too.&#8221;</p>
<p>Many experts are debating whether gas could reach $5 a gallon by this summer. That could potentially cripple many businesses.</p>
<p>&#8220;If it stays there for too long, it will be a problem,&#8221; Rodriguez said. &#8220;I think sales are going to go down.&#8221;</p>
<p>Rodriguez said the key to keeping gas prices reasonable is not action by lawmakers in Washington, but in how all Americans act.</p>
<p>&#8220;It&#8217;s up to us to control how much we drive, how hard we drive, what kind of cars do we drive. I&#8217;m not sure Washington can do much except drill more in more dangerousplaces,&#8221; he said.</p>

			<content:encoded><![CDATA[<!-- Start Shareaholic LikeButtonSetTop Automatic --><!-- End Shareaholic LikeButtonSetTop Automatic --><p>I have two  interesting stories on Apple and the iPad to reflect on today.</p>
<p>First, ABC&#8217;s Nightline recently became the first Western journalists actually welcomed into an Apple assembly plant in China. The show recently aired a 15 minute feature on working conditions inside Apple&#8217;s Foxconn factory in Shenzhen, China last week. Watch the video and then scroll down for what may be some additional surprising news about Apple&#8217;s operations in China.</p>
<p><iframe src="http://www.youtube.com/embed/hLuPtMvvwA0" frameborder="0" width="560" height="315"></iframe></p>
<p>Next, the story that has gone unreported lately is a University of California study titled <em><a href="http://pcic.merage.uci.edu/papers/2011/Value_iPad_iPhone.pdf" target="_blank">&#8220;Capturing Value in Global Networks: Apple’s iPad and iPhone&#8221;</a></em>. The study&#8217;s most interesting finding, in my opinion, is the tiny percentage of the total value of Apple&#8217;s iPhone and iPad that actually goes to the Chinese manufacturers of the products. The charts below, from the study, show how the value is divided among the various groups involved it their production and sales:</p>
<p><a href="http://welkerswikinomics.com/blog/wp-content/uploads/2012/02/iPad.png"><img class="aligncenter size-full wp-image-2949" title="iPad" src="http://welkerswikinomics.com/blog/wp-content/uploads/2012/02/iPad.png" alt="" width="488" height="314" /></a></p>
<p><a href="http://welkerswikinomics.com/blog/wp-content/uploads/2012/02/iPhone.png"><img class="aligncenter size-full wp-image-2950" title="iPhone" src="http://welkerswikinomics.com/blog/wp-content/uploads/2012/02/iPhone.png" alt="" width="489" height="313" /></a></p>
<p><em><a href="http://www.economist.com/node/21543174" target="_blank">The Economist</a> </em>provides the analysis:</p>
<blockquote><p>The chart shows a geographical breakdown of the retail <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/price/" title="Glossary: Price" onmouseover="tooltip.show('This is the amount paid for a good determined by the supply and demand for the good in the market. Price rises and falls as demand and supply rise and fall.');" onmouseout="tooltip.hide();">price</a> of an iPad. The main rewards go to American shareholders and workers. Apple’s <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/profit/" title="Glossary: Profit" onmouseover="tooltip.show('The payment to the entrepreneur in the resource market. A business owner expects to earn a "normal" level of profit, otherwise it will not be worth his while to remain in a market. In this regard, profit is a cost of production, because if a minimum profit is not earned a firm will shut down.');" onmouseout="tooltip.hide();">profit</a> amounts to about 30% of the sales price. Product design, software <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/development/" title="Glossary: Development" onmouseover="tooltip.show('Improvements in standards of living of a nation measured by income, education and health');" onmouseout="tooltip.hide();">development</a> and marketing are based in America. Add in the profits and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/wage/" title="Glossary: Wage" onmouseover="tooltip.show('The payment to labor in the resource market.');" onmouseout="tooltip.hide();">wages</a> of American suppliers, and distribution and retail costs, and America retains about half the total value of an iPad sold there. The next biggest gainers are South Korean firms like Samsung and LG, which provide the display and memory chips, whose profits account for 7% of an iPad’s value. The main financial benefit to China is wages paid to workers for assembling the product and for manufacturing some inputs—equivalent to only 2% of the retail price.</p></blockquote>
<p>A student today asked why Apple doesn&#8217;t produce its products in the United States, where an economic downturn has left 14 million American out of work for the last three or four years. If iPads and iPhones were just made in America, jobs could be created, households would have more <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/income/" title="Glossary: Income" onmouseover="tooltip.show('The money earned by households for providing their resources (land, labor and capital) to firms in the resource market. Incomes include wages, interest, rent and profit.');" onmouseout="tooltip.hide();">income</a> to spend on Apples products, and both the country and the economy would benefit.</p>
<p>The data in the UC study indicates that in fact, more than half the value of an iPad or iPhone does end up in the hands of Americans. But Apple could never achieve the low costs and high profits that it does by assembling its products in the US. After watching the Nightline video above, it should be clear that the type of production involved in Apple factories&#8217; is very low-skilled and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/labor/" title="Glossary: Labor" onmouseover="tooltip.show('The work undertaken by humans towards the production of goods and services');" onmouseout="tooltip.hide();">labor</a>-intensive. Using American labor, with its unions, minimum wages and 40 hour work weeks, would require Apple to employ such large numbers of workers and raise the company&#8217;s <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/variable-cost/" title="Glossary: Variable Cost" onmouseover="tooltip.show('Costs which change with the level of output in the short-run. Typically these are the labor costs and raw material costs a firm faces. To produce more of a good in the short-run, more labor and raw materials are needed, so variable costs increase as output increases.');" onmouseout="tooltip.hide();">variable cost</a> to such a level that the firm&#8217;s profits would be reduced significantly and its sales would fall dramatically. Apple would lose out to foreign producers of smart phones and tablet computers, such as LG, Samsung, Sony and others, which would continue assembling their <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/goods/" title="Glossary: Goods" onmouseover="tooltip.show('The physical output of a firm producing a product meant for sale and consumption in a product market. Contrast with services, which are non-physical products produced and sold by firms to consumers.');" onmouseout="tooltip.hide();">goods</a> with Chinese labor.</p>
<p>Ultimately, any gain to the low-skilled American workers (presuming Apple could even find enough to do the work of the 400,000 Chinese employed in the production of Apple products in China), would be offset by a loss of profits enjoyed by the millions of Americans who hold shares in Apple Computer and the thousands of American who are employed engineering and designing its products, as the firm&#8217;s sales would slip in the face of lower-cost competitors.</p>
<p>So this student&#8217;s question identifies an interesting paradox: America, with its large pool of unemployed workers, will never be attractive as a place to produce labor-intensive products such as phones and tablet computers, due to the vast wage differential between the US and China. And even if one firm did decide to produce its products in America, the gains to low-skilled workers who may find minimum wage work in the new assembly plants would be off-set by losses to the firms&#8217; shareholders and the high-skilled workers whose jobs would be lost as sales decline due to the lower prices offered by lower-cost competitors.</p>
<p>The lesson here is two-fold: First, Apple and other American technology companies should continue using Chinese labor to assemble their products, and second, America is better off for it: lower costs mean cheaper products and higher sales, thus greater employment in the high-skilled sectors of the US economy, and more profits and returns on the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/investment/" title="Glossary: Investment" onmouseover="tooltip.show('A component of aggregate demand, it includes all spending on capital equipment, inventories, and technology by firms. This does not include financial investment, which is the purchase of financial assets (stocks and bonds), not included in GDP because they are only purely financial investments.');" onmouseout="tooltip.hide();">investments</a> of shareholders in American corporations. Americans are richer and enjoy a higher standard of living thanks to the millions of Chinese working in factories assembling the goods we consume.</p>
<p>Keep in mind, this analysis did not even consider the effect on the Chinese economy and the millions of Chinese workers (whose lives are much harder than the typical American) should companies like Apple shut down their Chinese manufacturing plants. That&#8217;s a whole other blog post!</p><div class="shr-publisher-2945"></div><!-- Start Shareaholic LikeButtonSetBottom Automatic --><!-- End Shareaholic LikeButtonSetBottom Automatic --><p>Related posts:<ol>

</ul>
<p>Instead of simply answering the questions in a test or quiz, the students were asked to create a dialogue for two cartoon actors to engage in using the Xtranormal animation software.</p>
<p>Below is one of the more original animations that resulted. This one was created by my student Simon, whose superhero &#8220;Market Man&#8221; challenges an unethical businessman to come clean about his practice of not revealing all the information about his products ot buyers. Scroll down below the video to see the rest of the assignment instructions. Great job, Simon!</p>

<p><strong>The assignment is as follows:</strong></p>
<ol>
<li>Create a free account on <a href="http://www.xtranormal.com" target="_blank">Xtranormal.com</a> or log in using one of your other online accounts.</li>
<li>Once logged in, click the &#8220;Create&#8221; tab.</li>
<li>Choose one of the themes for your video. Notice, however, that you have only 300 xp (xtranormal points) to use in the production of your video, so some of the themes you cannot use for free.</li>
<li>Once you&#8217;ve chosen a theme you can afford to make a video on, choose the question you wish to answer in your video.</li>
<li>Think about how to best answer the question in dialogue form. It is recommended that rather than simply answering the question like you would on a written test or quiz, you have your two characters engage in a conversation about the topic. Another suggestion would be to show a simulated transaction in which the main idea of the topic is illustrated.</li>
<li>Experiment with camera angles, expressions, gestures, sounds and so on. While your grade will be based wholly on the content of your dialogue, production quality can certainly add to the entertainment value of your video.</li>
<li>Keep your video between 4 and 5 minutes in length. Either of the two questions should be able to be addressed in this amount of time. Be sure to preview your video before publishing, otherwise you will spend your xp points and not have enough to make changes later on.</li>
<li> When you have previewed the video and re happy with it, publish it to the Xtranormal site. After it has finished rendering, view your video and copy the embed code, then log into our class Posterous page (<a href="http://zis-economics.posterous.com/" target="_blank">zis-economics.posterous.com</a>) and past the embed code into the html screen of a new post. Publish your video on that page for your teacher to see. Make sure you name is included in the post.</li>

			<content:encoded><![CDATA[<!-- Start Shareaholic LikeButtonSetTop Automatic --><!-- End Shareaholic LikeButtonSetTop Automatic --><p>Teaching at an international school affords me the privilege of encountering and learning from truly unique and diverse individuals. Last week, my Economics classes were lucky to have as a guest speaker one very interesting and inspirational young man named Andrew Cunningham. Andrew, originally from Vermont, graduated from Duke University in 2008 and has helped co-found a non-governmental organization (NGO) focused on promoting grassroots strategies for economic <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/development/" title="Glossary: Development" onmouseover="tooltip.show('Improvements in standards of living of a nation measured by income, education and health');" onmouseout="tooltip.hide();">development</a>. <a href="http://www.wisergirls.org">WISER (Women&#8217;s Institute for Secondary Education and Research)</a> serves a community of 35,000 in Kenya&#8217;s Muhuru Bay, an area where the per capita <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/income/" title="Glossary: Income" onmouseover="tooltip.show('The money earned by households for providing their resources (land, labor and capital) to firms in the resource market. Incomes include wages, interest, rent and profit.');" onmouseout="tooltip.hide();">income</a> is around $1 a day and 38% of the population is HIV positive.<a href="http://www.wisergirls.org/"><img src="http://welkerswikinomics.com/blog/wp-content/uploads/2009/11/110809_1759_EconomicDev11.png" alt="" align="right" border="0" /></a></p>
<p>Traditionally, less than 5% of young girls complete primary school in Muhuru Bay. In the town&#8217;s history, only ONE girl has ever gone to university (she would become the only Muhuru Bay native to complete her PhD and would eventually co-found WISER with Andrew). A combination of tradition, culture, and most importantly poverty had prevented improvements in the plight of woman in this poor corner of Africa. What was needed, decided Andrew and his founding partners, was an all-girls boarding school where opportunities for young women were promoted and academic achievement encouraged and fostered. WISER opened the community&#8217;s first all-girls secondary school in 2010 to 130 local girls who had made it through primary school.</p>
<p>Beyond female education, WISER have embarked on several other development projects in the last year and a half. In his visit to our IB Economics class, Andrew told the story of human development in Muhuru Bay as occurring primarily in three realms.</p>
<ul>
<li><em>Education, </em></li>
<li><em>health, and </em></li>
<li><em><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/entrepreneurship/" title="Glossary: Entrepreneurship" onmouseover="tooltip.show('The creativity and innovation an individual business owner puts towards the production of goods and services.');" onmouseout="tooltip.hide();">entrepreneurship</a>.</em></li>
</ul>
<p>I will briefly summarize the three main development strategies WISER has employed in Muhuru Bay, starting with education.</p>
<p><strong>Education as a development strategy:<br />
</strong></p>
<p>Education is a primary and fundamental strategy for eradicating poverty. A nation&#8217;s <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/human-capital/" title="Glossary: Human capital" onmouseover="tooltip.show('The value of labor created through education, training, knowledge and health. An important determinant of aggregate supply and the level of economic growth in a nation.');" onmouseout="tooltip.hide();">human <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/capital/" title="Glossary: Capital" onmouseover="tooltip.show('Human-made resources (machinery and equipment) used to produce goods and services; goods which do not directly satisfy human wants.');" onmouseout="tooltip.hide();">capital</a></a> is its most vital resource, and the road to prosperity requires an effective education system that does not discriminate based on race, gender, or socioeconomic status. In Muhuru Bay, which is 14 hours by car across un-paved roads from Kenya&#8217;s capitol, the education system had failed to achieve meaningful results, both for boys and girls. Student performance on national examinations across the primary grade levels had historically averaged around 11% passing rates. Boys out-performed girls, but as a whole only about one in ten Muhuru Bay children passed the examination required for admittance to secondary school in Kenya.</p>
<p>WISER wished to improve this dismal statistic. If they were going to build a secondary school for girls, they would need to first get girls to pass the national exam for entrance to secondary school, or else their new building would be full of empty desks.</p>
<p>Andrew first talked to my class about the <em>traditional</em> <em>development community</em> (think <a href="http://www.worldbank.org/">World Bank</a>, <a href="http://www.unicef.org/">UNICEF</a>, <a href="http://www.usaid.gov/">USAID</a>) approach to promoting education in Africa. You are probably thinking the way to <em>help</em> these kids is to <em>give them resources to improve their education. </em>Build better schools, give them textbooks and school supplies, maybe uniforms, build a library, electricity in the classroom, chalk boards, heck, how about we <a href="http://laptop.org/en/">give them laptop computers</a>! All of these ideas represent the <em>traditional development community&#8217;s </em>approach to improving education in poor countries. The problem is that these strategies focus only on the <em>inputs </em>into education, and completely fail to look at the <em>output.<br />
</em></p>
<p>Inputs and outputs are common topics of discussion in any Economics class. To produce <em>anything</em>, three resources are required: <em><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/land/" title="Glossary: Land" onmouseover="tooltip.show('Includes all natural resources needed to undertake production of goods or services: including soil, timber, minerals, fossil fuels, fresh water, livestock, fish, etc... "the gifts of nature"');" onmouseout="tooltip.hide();">land</a>, <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/labor/" title="Glossary: Labor" onmouseover="tooltip.show('The work undertaken by humans towards the production of goods and services');" onmouseout="tooltip.hide();">labor</a>, and capital</em>. The traditional approach to improving education in Africa focused primarily on the <em>land and capital.</em> Things such as pens, notebooks, laptops, and new libraries are great, but they have little actual impact on what gets <em>learned</em> in a school. The neglected factor was the labor (i.e. the <em>teachers!</em>) In Muhuru Bay, teachers were paid so miserably and worked in such dismal conditions that the <em><a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/incentive/" title="Glossary: Incentive" onmouseover="tooltip.show('Refers to the motivation an individual has to undertake a particular action.');" onmouseout="tooltip.hide();">incentive</a></em> to actually improve their students&#8217; results was just too weak! With passing rates at 11% on national exams, WISER set about figuring out how to use <em>incentives</em> to improve the outputs of education in Muhuru Bay.</p>
<p>A simple and relatively low-cost plan was put into action. Teachers were told that if their students&#8217; scores increased by only 15% on the exams, they would receive a 100% increase in their salary. Andrew and WISER worked with the national education ministry to develop interim exams that could be given quarterly to help the teachers measure their students&#8217; improvement before the annual national examination.</p>
<p>With only minimal <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/investment/" title="Glossary: Investment" onmouseover="tooltip.show('A component of aggregate demand, it includes all spending on capital equipment, inventories, and technology by firms. This does not include financial investment, which is the purchase of financial assets (stocks and bonds), not included in GDP because they are only purely financial investments.');" onmouseout="tooltip.hide();">investments</a> on the <em>land and capital </em><em>resources </em><em>(i.e. textbooks and classroom materials) <span style="font-style: normal;">in Muhuru Bay schools, and by spending less than $10,000 on teacher raises, the passing rate among Muhuru Bay schools increased in one year from 11% to 36%. Hundreds of students, boys and girls, who would not have been able to enter secondary school the previous year, instead passed the exam and were eligible for a secondary education, a crucial step towards a better future!</span></em></p>
<p>The teachers&#8217; incentive pay program was such a success in Muhuru Bay last year that the state government has taken notice and intends to implement it in other rural communities throughout Kenya. By focusing on the <em>outputs (student learning), </em>rather than the <em>inputs (classroom resources) </em>WISER has assured that when their all-girls school opens in January, its seats will be filled with qualified students who successfully completed their primary education.</p>
<p><strong>Health as a development strategy:<br />
</strong></p>
<p>The second topic of Andrew&#8217;s discussion with my IB Economics classes focused on health and sanitation, specifically solving the problem of <em>open defecation</em> (&#8220;OD&#8221; is a technical term used in the development community referring to the fact that in many poor communities basic latrines are non-existent, and therefore people <em>shit</em> in the open). OD in Muhuru Bay contributed to the poor health and low life expectancy of locals; According to Andrew an estimated 60 people were dying <em>each year</em> of cholera, a disease spread via human waste.</p>
<p>In the health realm of traditional economic development programs, the same basic dilemma between focusing on the <em>inputs</em> or the <em>outputs </em>had stymied previous attempts to reduce OD in Muhuru Bay. Recently, an outside aid organization had made loans to the community to build 30 public latrines. Within a year, however, the latrines had fallen into disrepair and were essentially useless. When Andrew and his team asked the community members why they had let the latrines fall into such a poor state, their answer was predictable. These were not <em>their </em>latrines, they belonged to the aid organization that had built the latrines. If they were broken, the aid organization could fix them! Such logic reflects a common problem in economics, that of <em><a href="http://www.econclassroom.com/?p=2945" target="_blank">the tragedy of the commons</a></em>. Because the latrines were public, <em>no one owned them</em>. Because no one owned them, <em>no one cared for them</em>. When the latrines fell out of repair, people quickly reverted back to OD, and instances of cholera and other diseases increased once more.</p>
<p>WISER decided to tackle this problem using a similar approach as the one used to fix primary education in Muhuru Bay, by focusing on the <em>output</em>, rather than the inputs. In this case, the goal was simple: create <em>incentives</em> for people to build their OWN latrines, which they would then have an incentive to take care of and use. The strategy for promoting personal latrines they decided to employ is one that has been successfully implemented throughout the developing world, and is now funded by UNICEF, which trains facilitators to go into a community and in a very short time, and at a very low cost, incentivize the locals to take sanitation into their own hands and build their own latrines.</p>
<p><a href="http://www.communityledtotalsanitation.org/page/clts-approach">Community Led Total Sanitation (CLTS)</a> is a mind-blowing and shockingly blunt way to promote sanitation. Rather than spending thousands of dollars to build public latrines, the CLTS approach brings community members together for an afternoon of discussion and education about sanitation issues. Locals are asked to take an index card and go to &#8220;where they shit&#8221; and collect a sample of <em>their own waste</em>. A large pile of human waste is placed on a table in front of a room full of locals right next to a large selection of delicious foods. The facilitator then goes about discussing basic facts related to OD in the community, such as &#8220;If you added up all the shit your community produces in a year, how many donkeys would it weigh as much as?&#8221; or, &#8220;How many bags of rice would you have to eat to create this much shit?&#8221; In the mean time, of course, hundreds of flies have descended on the pile of waste in the front of the room, and the community members look on in utter disgust as the flies jump from the feces to the food and back again.</p>
<p>At the end of the lecture, the facilitator turns to the food and says, &#8220;Well, it&#8217;s time for lunch, who&#8217;s hungry?&#8221; In utter disgust, the locals ask the facilitator if he has gone mad. The lesson, of course, is that the food and water the community consumes is most likely being contaminated by the waste they produce and deposit in the open around their village. Within a few weeks of the CLTS project in Muhuru Bay, 256 new latrines were built by the community members themselves. Whereas previously, only around 15% of the locals used latrines regularly, after the CLTS project around 75% had access to the &#8220;facilities&#8221;.</p>
<p>The <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/total-cost/" title="Glossary: Total cost" onmouseover="tooltip.show('The total expenditures made by a firm on land, capital, labor and the entrepreneurship of the business owner towards the production of a good or service at a particular level of output.');" onmouseout="tooltip.hide();">total cost</a> of the CLTS sanitation project? Around $55, a tiny fraction of the cost of building the public latrines that had previously been neglected by the community. By focusing on the outputs rather than the inputs, real development in the health of the community was achieved at a very low financial cost.</p>
<p><strong>Entrepreneurship and micro-lending as a development strategy:<br />
</strong></p>
<p>The final approach to human development in Muhuru Bay Andrew discussed with my classes focused on the <em>economic empowerment</em> of community entrepreneurs. Micro-lending is a much talked about and widely used development strategy that provides financial credit or technology loans to entrepreneurs in poor communities to create small businesses, ideally ones with a socially beneficial purpose. Watch the first 12 minutes of the video below to get a better idea of the history and purpose of micro-finance as a strategy for achieving economic development.</p>

<p>In Muhuru Bay, the micro-lending scheme Andrew has pioneered involved not financial capital, but <em>physical capital </em>(i.e. technology).</p>
<p>WISER was able to secure several technology donations, including a copy machine, several laptop computers with cellular internet connections, a foot pump for water, and a digital LCD projector. WISER then solicited loan requests from several &#8220;young entrepreneurs&#8221;. Young men and women wrote business plans outlining how they would use the technology loans to generate income for themselves and the community, and provide <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/services/" title="Glossary: Services" onmouseover="tooltip.show('The non-physical output of firms meant for consumption in a product market. Services are "non-tangible" goods, such as taxi rides, accounting, doctor visits, teaching, and other products that can be bought and sold, but not physically consumed.');" onmouseout="tooltip.hide();">services</a> that would benefit others in the Muhuru Bay community. The technology would not be <em>donated </em>to the recipients; rather they would be required to pay back the value of the capital through their business revenues.</p>
<p>It is simply amazing how a few pieces of second-hand technology, items that we in the rich North would take for granted as relatively common and thus of very little social or economic value, can completely change a poor community in Africa for the better. Here&#8217;s how some of the capital Andrew and WISER loaned to young entrepreneurs were put to use to achieve meaningful development in Muhuru Bay:</p>
<ul style="margin-left: 38pt;">
<li>The copy machine was installed and powered by a generator. It was the first such machine ever installed in Muhuru Bay. Local businesses, students, job seekers and other could now, for a few cents, photo-copy their documents locally, avoiding the two hour drive previously required for such a service.</li>
<li>The laptops were installed in an internet café and made available to local students and businesses. Farmers and fisherman could check product <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/price/" title="Glossary: Price" onmouseover="tooltip.show('This is the amount paid for a good determined by the supply and demand for the good in the market. Price rises and falls as demand and supply rise and fall.');" onmouseout="tooltip.hide();">prices</a> in the cities hours away, increasing efficiency and bargaining positions when middle-men came to town to buy their produce. Job openings in the city newspapers&#8217; classifieds could be printed and posted for the local community to see, improving information symmetry between the poor countryside and the cities where job opportunities existed. The cost of access to these services was cheap, yet the entrepreneurs who were granted the laptop loan were able to pay back the cost of the technology in no time at all, and the community as a whole benefited from their existence.</li>
<li>My favorite entrepreneurial venture involved the LCD projector. This piece of technology, which now hangs from the ceiling of thousands of classrooms around the rich world, had never before been seen in Muhuru Bay. You may think it ended up in a classroom or in an office building, but no; the entrepreneurs who received the projector hooked it up to a satellite dish which captured and projected English Premier League football matches onto the wall of a large room in a local building. The business was to sell tickets to local football fans who were more than happy to pay to watch English football matches in full color on a wall-sized screen. Before the projector, dozens would have huddled around a tiny television with poor reception to watch football matches. The &#8220;football theater&#8221; business was the most successful of all, and paid back its loan fastest.</li>
</ul>
<p>All three of these entrepreneurial endeavors were very low cost, using donated technologies. The reason for their successes, however, must be attributed to the model for implementation. They were not simply &#8220;given&#8221; to the community. Such a strategy would certainly have led to the same &#8220;<a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/tragedy-of-the-commons/" title="Glossary: Tragedy of the commons" onmouseover="tooltip.show('When there exists a common access resource, over which there is no private owner, the incentive among rational users of that resource is to exploit it to the fullest potential in order to maximize their own self gain before the resource is depleted. The tragedy, therefore, is that common resources will inevitably be depleted due to humans’ self-interested behavior, leaving us with shortages in key resources essential to human survival.');" onmouseout="tooltip.hide();">tragedy of the commons</a>&#8221; experienced when the outside aid organization funded the construction of public latrines. The capital would have been neglected and fallen into disrepair. By lending the technology to businesses, however, the incentive for innovative and socially beneficial ventures was created, and a business model was developed to best utilize the resources in a <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/profit/" title="Glossary: Profit" onmouseover="tooltip.show('The payment to the entrepreneur in the resource market. A business owner expects to earn a "normal" level of profit, otherwise it will not be worth his while to remain in a market. In this regard, profit is a cost of production, because if a minimum profit is not earned a firm will shut down.');" onmouseout="tooltip.hide();">profit</a>-earning, sustainable manner. With very little inputs, fantastic outputs were achieved, enriching not only the entrepreneurs, but the entire Muhuru Bay community.</p>
<p><strong>Economic Development the WISER Way:<br />
</strong></p>
<p>Andrew&#8217;s visit to Zurich International School was eye-opening in many ways. He brought to light both the successes of WISER and other community projects in rural Kenya, but also shined a light on the failures of the traditional development community&#8217;s agenda. When I think about the hundreds of billions of dollars that have been committed to economic development in Africa over the past decades, and on into future decades, I wonder whether the diplomats and the politicians in the &#8220;aid community&#8221; have any idea how much has been accomplished on the ground in places like Muhuru Bay thanks to community-based organization like WISER.</p>
<p>With so <em>little</em>, so <em>much</em> can be accomplished. The poor of Africa and the world need resources, but more importantly they need education, health and sanitation, and business opportunities so that they can enjoy the benefits of development from the bottom up. Development aid, as it has traditionally been distributed, comes from the top down, funneled through national governments. Waste and corruption are rampant, and typically only a fraction of what has been given ends up on the ground in places like Muhuru Bay. Even when it does, the <em>tragedy of the commons</em> often results in inefficiency and waste, as the &#8220;inputs&#8221; are managed and distributed from the top down, leading to uncertainty of ownership and misaligned incentives once the resources are on the ground.</p>
<p>Perhaps aid from the outside is still needed, but Andy&#8217;s visit showed me and my students that something much more basic lies at the core of successful economic development. Education focusing on outputs rather than inputs, sanitation focusing on outputs rather than inputs, and entrepreneurship that empowers business leadership, have improved the lives of thousands in one Kenyan community. What could such a re-thinking of development strategies do for the rest of Africa and the developing world?</p><div class="shr-publisher-1269"></div><!-- Start Shareaholic LikeButtonSetBottom Automatic --><!-- End Shareaholic LikeButtonSetBottom Automatic --><p>Related posts:<ol>

			<content:encoded><![CDATA[<!-- Start Shareaholic LikeButtonSetTop Automatic --><!-- End Shareaholic LikeButtonSetTop Automatic --><p>As we study economic development in year 2 IB Economics, we examine different models for economic growth. Growth in GDP is not the only determinant of economic development, which in order to be measured effectively must account for human welfare determinants such as life expectancy, literacy rates, child mortality rates, distribution of income, and so on. However, it has been shown throughout history that economic growth, or the increase in real output and income, correlates directly with improvements in development factors like those above.</p>
<p>The reason? Increases in <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/national-income/" title="Glossary: National income" onmouseover="tooltip.show('Another term for the GDP of a nation. Measures the total income earned by households in the resources market for their provision of labor, land, capital and entrepreneurship to the nation's producers.');" onmouseout="tooltip.hide();">national <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/income/" title="Glossary: Income" onmouseover="tooltip.show('The money earned by households for providing their resources (land, labor and capital) to firms in the resource market. Incomes include wages, interest, rent and profit.');" onmouseout="tooltip.hide();">income</a></a> usually mean at least some levels of improvement in access to basic necessities for the average citizen in a developing country. Also, higher incomes mean more savings, which means greater access to <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/capital/" title="Glossary: Capital" onmouseover="tooltip.show('Human-made resources (machinery and equipment) used to produce goods and services; goods which do not directly satisfy human wants.');" onmouseout="tooltip.hide();">capital</a> for <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/investment/" title="Glossary: Investment" onmouseover="tooltip.show('A component of aggregate demand, it includes all spending on capital equipment, inventories, and technology by firms. This does not include financial investment, which is the purchase of financial assets (stocks and bonds), not included in GDP because they are only purely financial investments.');" onmouseout="tooltip.hide();">investment</a> by entrepreneurs. More investment leads to greater <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/productivity/" title="Glossary: Productivity" onmouseover="tooltip.show('The output per unit of input of a resource. An important determinant of the level of aggregate supply in a nation.

Furthermore, rising incomes mean more <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/taxes/" title="Glossary: Tax" onmouseover="tooltip.show('A payment made by an individual or a firm to the government, usually levied on income, property or the consumption of goods and services.

Because of these characteristics, private sector firms have little or no incentive to produce them, since they would be impossible to sell. Therefore, government must provide public goods.

<p>Of course, the following models can be observed to varying degrees among the world&#8217;s developing economies today. Some of these models will fail to play out if the institutional and political environment fails to create a stable atmosphere for savings and investment. What you should notice, however, is the underlying importance of savings in all three models. Poor countries suffering from low savings and, even worse, <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/capital-flight/" title="Glossary: Capital Flight" onmouseover="tooltip.show('When the scarce capital available to a less developed country leaves for the safety and security of a more developed economy. Financial capital flight occurs when savers prefer to put their money in foreign banks to domestic banks, reducing the supply of loanable funds in a poor county. Human capital flight is also known as "brain drain" when the skilled workers in a poor country prefer to seek work in a richer country, reducing the production possibilities of the less developed country. ');" onmouseout="tooltip.hide();">capital flight</a>, are doomed to a cycle of poverty, where funds for investment leading to productivity increases are never made available due to instable institutions like banking and politics. To put a poor country on a path towards economic growth and <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/development/" title="Glossary: Development" onmouseover="tooltip.show('Improvements in standards of living of a nation measured by income, education and health');" onmouseout="tooltip.hide();">development</a>, a strategy is needed. Such strategies will be covered in a later post. For now, let&#8217;s look at the models:</p>
<p><strong>Harrod-Domar Growth Model:</strong><a title="HD model" href="http://welkerswikinomics.com/blog/wp-content/uploads/2008/02/growthmodels_1.jpeg"><img title="HD model" src="http://welkerswikinomics.com/blog/wp-content/uploads/2008/02/growthmodels_1.jpeg" alt="HD model" width="356" height="239" align="right" /></a></p>
<p>The model suggests that the economy&#8217;s rate of growth depends on:</p>
<ol>
<li><em> the level of saving</em></li>
<li><em> the productivity of investment i.e. the capital output ratio</em></li>
</ol>
<p>The Harrod-Domar model was developed to help analyse the <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/business-cycle/" title="Glossary: Business Cycle" onmouseover="tooltip.show('A model showing the short run periods of contraction and expansion in output, resulting from fluctuations in the level of aggregate demand, experienced by an economy over a period of time.');" onmouseout="tooltip.hide();">business cycle</a>. However, it was later adapted to &#8216;explain&#8217; economic growth. It concluded that:</p>
<ul>
<li>Economic growth depends on the amount of labour and capital.</li>
<li>As LDCs often have an abundant <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/supply/" title="Glossary: Supply" onmouseover="tooltip.show('A schedule or curve showing the direct relationship between the quantity of output firms produce in a particular period of time and the various prices of the good.');" onmouseout="tooltip.hide();">supply</a> of labour it is a lack of physical capital that holds back economic growth and development.</li>
<li>More physical capital generates economic growth.</li>
<li>Net investment leads to more capital accumulation, which generates higher output and income.</li>
<li>Higher income allows higher levels of saving.</li>
</ul>
<p><strong>Lewis Structural Change (dual-sector) Model:</strong></p>
<p><a title="Lewis model" href="http://welkerswikinomics.com/blog/wp-content/uploads/2008/02/growthmodels_2.jpeg"><img src="http://welkerswikinomics.com/blog/wp-content/uploads/2008/02/growthmodels_2.jpeg" alt="Lewis model" width="425" height="245" align="right" /></a></p>
<p>Many LDCs have dual economies:</p>
<ul>
<li>The traditional agricultural sector was assumed to be of a subsistence nature characterised by low productivity, low incomes, low savings and considerable underemployment.</li>
<li>The industrial sector was assumed to be technologically advanced with high levels of investment operating in an urban environment.</li>
</ul>
<p>Lewis suggested that the modern industrial sector would attract workers from the rural areas.</p>
<ul>
<li>Industrial firms, whether private or publicly owned could offer <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/wage/" title="Glossary: Wage" onmouseover="tooltip.show('The payment to labor in the resource market.');" onmouseout="tooltip.hide();">wages</a> that would guarantee a higher quality of life than remaining in the rural areas could provide.</li>
<li>Furthermore, as the level of labour productivity was so low in traditional agricultural areas people leaving the rural areas would have virtually no impact on output.</li>
<li>Indeed, the amount of food available to the remaining villagers would increase as the same amount of food could be shared amongst fewer people. This might generate a <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/surplus/" title="Glossary: Surplus" onmouseover="tooltip.show('When the quantity supplied of a good is greater than the quantity demanded. Also called "excess supply". A surplus will occur if the price in a market is greater than the equilibrium price, for example, due to a government price floor.');" onmouseout="tooltip.hide();">surplus</a> which could them be sold generating income.</li>
</ul>
<p>Those people that moved away from the villages to the towns would earn increased incomes:</p>
<ul>
<li>Higher incomes generate more savings.</li>
<li>Increased savings meant more fund available for investment.</li>
<li>Increased investment meant more capital and increased productivity in the industrial sector, higher wages, more <a class="glossaryLink" href="http://welkerswikinomics.com/blog/glossary/incentive/" title="Glossary: Incentive" onmouseover="tooltip.show('Refers to the motivation an individual has to undertake a particular action.');" onmouseout="tooltip.hide();">incentive</a> to move from low productivity agriculture to high productivity industry, the circle continues&#8230;</li>
</ul>
<p><strong>Rostow&#8217;s Model &#8211; the 5 Stages of Economic Development:</strong><a title="Rostow Model" href="http://welkerswikinomics.com/blog/wp-content/uploads/2008/02/growthmodels_3.jpeg"><img src="http://welkerswikinomics.com/blog/wp-content/uploads/2008/02/growthmodels_3.jpeg" alt="Rostow Model" width="420" height="242" align="right" /></a></p>
<p>In 1960, the American Economic Historian, WW Rostow suggested that countries passed through five stages of economic development.</p>
<p>According to Rostow development requires substantial investment in capital. For the economies of LDCs to grow the right conditions for such investment would have to be created. If aid is given or foreign direct investment occurs at stage 3 the economy needs to have reached stage 2. If the stage 2 has been reached then injections of investment may lead to rapid growth.</p><div class="shr-publisher-312"></div><!-- Start Shareaholic LikeButtonSetBottom Automatic --><!-- End Shareaholic LikeButtonSetBottom Automatic --><p>Related posts:<ol>
