Dear year 2 IB Economics students,

Welcome back and I hope you enjoyed your time off. Before breaking for summer we were in the midst of our unit on Macroeconomics, just beginning our debate on whether or not government intervention in the economy in order to kick start activity during a deep recession was a good or bad idea. In other words, would the economy correct itself or would government stimulus be necessary to get our economy moving again.

As you all know, exactly a year and a half ago, the US government decided that in order to a avoid a recession as potentially devastating as the Great Depression of the 1930’s, government interaction into the economy was necessary. 787 billion dollars was put aside for government sponsored projects, transfer payments and decreases in taxes. The hope was that this spending would not only help people maintain their current jobs but also create jobs for those who had recently become unemployed. A year and a half later, proponents of the stimulus package, Keynsians if you will, believe that this great experiment has been a success and that if nothing had been done the economy would be in much worse shape. Opponents of the spending believe that the bill has simply postponed the self correcting forces in the economy and has instead created what economists call a double dip recession where the increase in government spending only creates a temporary, unsustainable increase in economic activity. In fact many of these opponents say that we are worse off now as the government is now further in debt due to the spending.

Has the great experiment thought up by John Maynard Keynes over half a century ago been a success or was it a solution that has caused more harm than good, potentially making the recession worse than it would have been? The radio show Plant Money recently dedicated a show to addressing this very issue. In order to get a balanced look, they interviewed two prominent economists, Tyler Cowen, a Professor of Economics at George Mason University and Mark Zandi, Chief Economist at Moody’s Analytics. Cowen, a skeptic of Keynesian spending, believes that we would now be better off if the government had not intervened in the economy. Zandi, on the other hand, is adamant that the US economy would be much worse off if the government had done nothing. Two economists analyzing similar data and coming up with very different conclusions. This is where economics becomes both complex and fascinating.

Keynes vs. Hayek: Late Economists Hip-Hop Legacy | PBS NewsHour | Dec. 16, 2009 | PBS.

A major theme of both the AP and IB Economics courses is the long-running debate between the Keynesian, demand-side theories of macroeconomic policy and those of the Classical, supply-side school. Today’s “Great Recession” has revived this debate, which itself dates back to the Great Depression of the 1930′s, when an Englishman and an Austrian could be found at the ideological centers of two different philosophies of the role government should play in the macroeconomy.

John Maynard Keynes and Friedrich Hayek were close friends whose views on government’s role differed greatly. Hayek was a classical, laissez faire libertarian who believed that any intervention by government in a nation’s economy disrupted the efficient functioning of the free market and threatened to stifle private enterprise. Keynes, the father, of course, of modern Keynesian economics, believed that free markets left unchecked were vulnerable to the volotile animal spirits of investors and speculators whose often irrational behaviors could create externalities such as unemployment and credit crunches, thereby harming society as a whole.

Paul Solman of PBS (who I recently met at an Economics teachers conference in Washington DC) interviews a modern Keynesian, Robert Skidelsky (Keynes’ biographer) and a neo-classical economist, Russ Roberts (who I also recently met in Richmond, VA).

YouTube - Chinas empty city – 10 Nov 09.

My buddy living in Shanghai posted this video to his Facebook profile today. It demonstrates how misaligned incentives in China lead local government officials to launch massive government infrastructure projects, all with the goal of meeting the growth targets handed down from Beijing.

Building roads to nowhere and cities that stand empty certainly creates jobs and new spending by the workers employed in their construction, so in that regard at least one goal of such projects is achieved. But whether or not all growth is good growth depends on whether efficiency in the economy is increase or decreased as a result of the growth strategies used.

Hundreds of billions of dollars worth of resources in China are currently being allocated by the government in Beijing towards massive public works projects such as this sparkling new city in remote Inner Mongolia. But it seems that government plans don’t always fall in line with the wishes of the nation’s people. A wise man once said, “build it… and they will come.” Apparently in China, that’s not always true.

I happen to have traveled in Inner Mongolia a few years ago with a group of students from my school in Shanghai. It was a sad thing in my opinion to witness the rampant development of the once pristine and culturally rich Inner Mongolian steppes. Ethnic Mongolians had been put on large reservations (not unlike the Native American people 150 years ago) and turned into tourist attractions. The cities were populated almost entirely with ethnic Han Chinese, there for the purpose of building more new cities, mining raw materials, and selling them to the rest of China’s industries.

Fiscal policy (the use of government spending and taxes to stimulate or reduce the overall level of demand in an economy) is a powerful tool for achieving the macroeconomic goals of full-employment, economic growth and price level stability. When used effectively, government spending can also improve efficiency in an economy by allocating society’s scarce resources towards socially and economically valuable projects. In China, it appears, the government’s incentives are aimed more towards pleasing the higher ups and continuing to inflate the speculative  bubble in real estate that has almost certainly formed, rather than pursuing socially desirable and allocatively efficient projects that actually help the Chinese people. Damn shame!

Discussion Questions:

1. What type of fiscal policy is the government in China pursuing? Expansionary or contractionary? What is the difference?
2. Why is government spending sometimes less efficient than private sector spending?
3. What would have been an alternative policy to allocating over $220 billion of public money into infrastructure projects that may have resulted in a more efficient allocation of China’s resources than projects such as the “empty city” in the video above?

Homo Economicus, the “Economic Man” is the concept underlying most economic theories. It holds that all humans are purely self-interested, rational actors who have the ability to make judgments that fulfill their subjectively defined ends. In modern economic theory, the end man seeks is generally accepted to be increasing monetary well-being and material wealth.

Philosophical foundations of “homo economicus“:

Aristotle (350 BC):

Again, how immeasurably greater is the pleasure, when a man feels a thing to be his own; for surely the love of self is a feeling implanted by nature and not given in vain, although selfishness is rightly censured; this, however, is not the mere love of self, but the love of self in excess, like the miser’s love of money; for all, or almost all, men love money and other such objects in a measure. And further, there is the greatest pleasure in doing a kindness or service to friends or guests or companions, which can only be rendered when a man has private property. These advantages are lost by excessive unification of the state.

• What does Aristotle think about the interference of government in the private property rights of man?
  

Adam Smith (1776):

In almost every other race of animals, each individual, when it is grown up to maturity, is entirely independent, and in its natural state has occasion for the assistance of no other living creature. But man has almost constant occasion for the help of his brethren, and it is in vain for him to expect it from their benevolence only. He will be more likely to prevail if he can interest their self-love of them. Whoever offers to another a bargain of any kind, proposes to do this. Give me that which I want, and you shall have this which you want, is the meaning of every such offer: and it is in this manner that we obtain from one another the far greater part of those good offices which we stand in need of. It is not from the benevolence of the butcher the brewer or the baker that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity, but to their self-love, and never talk to them of our own necessities, but of their advantages.

• How does Smith believe the pursuit of individual self-interest can lead to benefits for society as a whole?

John Stuart Mill (1836)

What is now commonly understood by the term “economics” is not the science of speculative politics, but a branch of that science. It does not treat of the whole of man’s nature as modified by the social state, nor of the whole conduct of man in society. It is concerned with him solely as a being who desires to possess wealth, and who is capable of judging of the comparative efficacy of means for obtaining that end. It predicts only such of the phenomena of the social state as take place in consequence of the pursuit of wealth. It makes entire abstraction of every other human passion or motive; except those which may be regarded as perpetually antagonizing principles to the desire of wealth, namely, aversion to labor, and desire of the present enjoyment of costly indulgences. These it takes, to a certain extent, into its calculations, because these do not merely, like our other desires, occasionally conflict with the pursuit of wealth, but accompany it always as a drag, or impediment, and are therefore inseparably mixed up in the consideration of it.

• According to Mill, labor is not something humans value for its own sake, but only because it allows us to do what?

Fredrick von Hayek (1930s):

We will benefit our fellow man most if we are guided solely by the striving for gain. For this purpose we have to return to an automatic system which brings this about, a self-directing automatic system which alone can restore liberty and prosperity.

• How would Hayek respond to those who argue that the government’s role in society and the economy is to promote fairness and equality?

Are you a “homo economicus“? - The Golden Balls Game

The prize: $1 million

How to play:

• Find an opponent from among your classmates.
• You and your opponent have never met before today, never spoken to one another, and will never see nor speak to one another again after the game ends.
• Since you do not know or care about your opponent, you must play this game with your own self-interest in mind, and assume that your opponent will play it with his or her self-interest in mind.
• You have in front of you two folded pieces of paper. One says “SPLIT” and one says “STEAL”
• You must decide which piece of paper to select, based on the following possible outcomes

The payoffs:

• If both players decide to “split”, each player will take home $500,000.
• If one player chooses to “split” and the other chooses to “steal” then the one who chooses to steel will take home $1 million, and the one who chose to split will get nothing
• If both players choose to “steel”, both players go home empty handed.

Let’s play!

• You only have one chance to play this game. Remember, you care only about yourself and should do what is best for you.
  
• On the teacher’s command, reveal your decision to your opponent.
  
• Take note of your payoff and report it to the teacher
  

Discussion:

• What was the outcome of your game?
  
• Was the outcome rational? Was it predictable?
  
• Did the outcome reflect the concept of “homo economicus“? Were you and your opponents’ decisions purely self-interested and coldly rational, intended to maximize your OWN payoff?
  
• Are you a homo economicus? What would homo economicus have done? Why?

“The Trap”: Intro to game theory and rational self-interest in politics and economics: http://www.youtube.com/watch?v=qzNcY-gZdiA&feature=related

• John Nash’s Game Theory proved that “a system driven by selfishness did not have to lead to chaos”, that “there could always be a point of equilibrium in which everyone’s self-interest is perfectly balanced against each other”? How does such a theory support the concept of homo economicus?
• What is the Prisoner’s Dilemma? “The rational choice is always to betray the other person.” What does this say about humans in society? Is government regulation needed to prevent constant betrayal by greedy, self-interested individuals? Or are constant betrayal and self-interest themselves capable of achieving a socially optimal outcome?

Noam Chomsky on the inefficiency of markets and the threat posed by de-regulation: http://www.youtube.com/watch?v=QPl27BO7fHE&feature=related

• What is the “externality” of financial market failure that Chomsky identifies?
• Why is the failure of a financial market more worrisome than the failure of a market like that for used automobiles?
• How does Chomsky feel about the de-regulation of financial markets? Does he think markets are always rational and efficient?

Modern applications of the concept of Homo Economicus:

• Rational Expectations Theory (RET): This economic theory assumes that humans acting generally in their own self-interest will make rational decision based on the best available information. Therefore, it assumes that people (and therefore, markets, which are made up of rational people) do not make systematic errors when predicting the future.
• Efficient Markets Hypothesis (EMH): Rooted in Rational Expectations Theory, which itself is rooted in the concept of homo economicus, EMH says that prices in markets, particularly financial markets (whose collapse has caused the today’s global economic crisis) represent the best possible estimates of the risks attached to the ownership of various financial assets (stocks, shares, bonds, etc…) Asset bubbles are therefore impossible, since “bubble” implies an irrational and unsustainable increase in the value of an asset which will ultimately “burst”. Markets are “self-correcting”, and the most effective tool for assuring economic stability is free markets, rather than government regulation or oversight.
  

Connecting the dots – from Homo Economicus to today’s Economic downturn:

The general acceptance of theories rooted in the concept of homo economicus led to the de-regulation of financial markets, which allowed money and resources to go whichever way the “market” (rational or not) determined.

• During the last decade, the market decided that more and more money and resources should go towards particular assets, specifically the United States mortgage market (the market for new homes in the US).
• As money flooded the US home mortgage market, it became cheaper and easier for Americans to get loans to build a home. GREAT, RIGHT?! Well, only until it came time to pay back those loans.
• Trillions of dollars worldwide became tangled up in the US mortgage market, representing households’ savings from around the globe.
• When Americans suddenly found their loans coming due, they found it hard to repay them due to adjustable interest rates and falling home price (supply had grown more rapidly than demand).
• American and many Europeans began defaulting on their mortgages, meaning all that money that had been lent to home buyers literally disappeared.
• Banks and financial markets faced a “liquidity crisis”, meaning they had no money.
• Lending stopped to households, firms, and other banks , meaning spending on goods and services decreased, meaning jobs were lost and economies entered recession.
• How could any of this have happened if the concept homo economicus and the economic theories based on the concept are correct? Are humans always rational, calculating, perfectly informed, self-interested beings acting purely in their own self-interest?

Conclusion: The concept of homo economicus has formed the basis for economic theories for centuries and for major macroeconomic policies over the last 30 years. Policies of “market liberalization” (freeing the market from the guiding, regulatory hands of government) have led to great prosperity, but even greater risk and volatility as irrational exuberance over asset prices has led to inefficient market outcomes, bubbles, and financial shocks plunging the “real” economies of the world into recession.

Perhaps a more complete understanding of humans is needed as the human science of economics enters a new era. The human as a cold, rational, calculating creature interested in only his own gain is an over-simplification, and forming theories and policies on such an assumption is dangerous. The future of economics must incorporate a more complete and complex understanding of human behavior if the economic crises of the last two years are to be avoided down the road.

Economics focus: Much ado about multipliers | The Economist

What is the goal of fiscal stimulus during a recession? Is it simply to increase nation’s total income by a certain amount determined by how much a government increases its own spending by? If this were the case, then an $800 billion stimulus package, like the one begun this year in the US, would lead to a total increase in national income of, well, exactly $800 billion.

While such an outcome is possible, it is not the desired outcome of the Obama administration and the economists who have supported the use of expansionary fiscal policy during economic downturns (i.e. the Keynesian school of economists). Keynesians expect that an initial increase in government spending (or a decrease in taxes) will result in households and firms increasing their own consumption and investment, meaning successive increases in spending. The initial change in spending ultimately gets multiplied through further rounds of spending. The total change in national income resulting from an initial change in government spending or taxes depends on the size of the fiscal multiplier. Now, this is where things get tricky! From the Economist:

The size of the multiplier is bound to vary according to economic conditions. For an economy operating at full capacity, the fiscal multiplier should be zero. Since there are no spare resources, any increase in government demand would just replace spending elsewhere. But in a recession, when workers and factories lie idle, a fiscal boost can increase overall demand. And if the initial stimulus triggers a cascade of expenditure among consumers and businesses, the multiplier can be well above one.

The above scenario, where an economy is operating below full-employment and government spending puts the nation’s idle resources to work, creates new income and further increases private spending, is precisely what the Obama team and its economists hope will happen in the US economy soon. A multiplier of above one means the $800 billion will ultimately increase America’s national income by something greater than $800 billion!

The multiplier is also likely to vary according to the type of fiscal action. Government spending on building a bridge may have a bigger multiplier than a tax cut if consumers save a portion of their tax windfall. A tax cut targeted at poorer people may have a bigger impact on spending than one for the affluent, since poorer folk tend to spend a higher share of their income.

Crucially, the overall size of the fiscal multiplier also depends on how people react to higher government borrowing. If the government’s actions bolster confidence and revive animal spirits, the multiplier could rise as demand goes up and private investment is “crowded in”. But if interest rates climb in response to government borrowing then some private investment that would otherwise have occurred could get “crowded out”. And if consumers expect higher future taxes in order to finance new government borrowing, they could spend less today. All that would reduce the fiscal multiplier, potentially to below zero.

Herein lies the controversy about the effectiveness of deficit-financed fiscal stimulus. Several posts on this blog have focused on the neo-classical, supply-side economists’ fears that expansionary fiscal policy financed by government borrowing will drive up interest rates to private borrowers, thereby “crowding-out” private investment, off-setting any expansion in output achieved through government spending. In the Keynesian model, however, it is precisely because interest rates have bottomed out at the “zero bound” (according to Paul Krugman) that government borrowing and spending will not lead to crowding-out, rather could actually increase investors’ willingness to spend (their “animal spirits”) on new capital, actually “crowding-in” private investment.

Alas, the debate continues. The ironic thing is that even years from now, after all of Obama’s stimulus money has been spent, and the US economy is either fully recovered or it is not, we still won’t know how large the fiscal multiplier was, since tomorrow’s economists will find it nearly impossible to isolate the variable of the $800 billion of government spending and determine just how much of America’s growth in income can be attributed to government spending, and how much resulted from automatic stabilizers built-in to help the economy recover on its own during recessions.

Discussion Questions:

1. Why do tax cuts for the rich tend to have a smaller multiplier effect than tax cuts for lower income households?
2. How can government borrowing drive up interest rates, and why is this a concern to policy makers deciding on the size of a fiscal stimulus package?
3. What are the animal spirits the article mentions? Where have you heard this expression before?
4. Do you think borrowing trillions of dollars and spending it to put people back to work and try to dig the US economy out of recession is wise, or should the US government be practicing better fiscal responsibility?

Once Considered Unthinkable, U.S. Sales Tax Gets Fresh Look – washingtonpost.com

Here in Switzerland I enjoy the luxury of having to pay a relatively small federal income tax of 9.6%. In the US, at my current income level, I would be paying a 25% federal income tax. On the other hand, everything I buy here in Switzerland, from food to clothes to train tickets and bike parts, costs me an additional 7.6% of value added tax. If a product is imported, chances are there is also an additional 20% import tariff. In other words, what I save coming in (because of the low direct tax) I lose going out (through high indirect taxes).

The incentive, therefore, is to save as much of my income as possible. I shop much less than I would in the US where indirect taxes are much lower, but when I do shop prices are much higher. Much of Switzerland’s government revenue comes from the value added tax and other indirect taxes, which means households keep much more of their earned income.

In the United States, where the government has not seen a balanced budget since 2001, there has been much talk about creating a national sales tax to help raise revenue to pay for many of the social plans that the Obama administration wants to pursue, such as national health care. VATs and sales taxes are regressive, which means more of the tax burden is born by low income households compared with high a direct, income tax, which is progressive, meaning the higher a household’s income, the greater percentage it pays. But with budget shortfalls expected to reach $4 trillion over the next four years, new sources of tax revenue are needed.

“Everybody who understands our long-term budget problems understands we’re going to need a new source of revenue, and a VAT is an obvious candidate,” said Leonard Burman, co-director of the Tax Policy Center, a joint project of the Urban Institute and the Brookings Institution, who testified on Capitol Hill this month about his own VAT plan. “It’s common to the rest of the world, and we don’t have it.”

The surge of interest in a VAT is testament to the extraordinary depth of the nation’s money troubles. While some conservatives have long argued that a consumption tax would provide a simpler and more efficient alternative to the byzantine U.S. income tax code, this time it’s all about the money.

To counter claims that a national sales tax is regressive, advocates point out that such a tax would allow the federal government to lower income tax rates for low income Americans, giving them more disposable income to spend on goods and services, which would be more expensive because of the VAT.

Another option the government should consider is a tax on greenhouse gas emissions. Currently, Obama is advocating a carbon permit market, which would be less effective at generating income for the government as permits, once they are issued or auctioned to industry, are bought and sold by firms, creating revenue for companies and not the government. A carbon tax, on the other hand, would create new tax revenue for the federal government and help reduce the negative externalities causing global warming and encourage development of alternative “green” methods of production.

In the short-term, it is unlikely that the US government will legislate any significant new taxes. Carbon taxes have been ignored by the Obama administration and Congress, under the argument that during a recession any new tax on industry might just break the nation’s manufacturing and energy sectors’ backs. A VAT is just as unpopular, for the reason that any policy raising consumer prices puts even greater burden on already strapped household incomes. Tradeable carbon permits are popular for the reason that they appear to be a “market based” approach to reducing greenhouse gas emissions; but Congress is talking about putting a price ceiling on carbon permits of $28 per ton, a price at which the incentives to reduce emissions among firms is minimal.

America’s long period of strong growth, low savings, and deficit financed government spending will necessitate belt-tightening in the near future as ultimately the government will have to start financing its budgets through tax revenues, not the issuing of new debt. Carbon taxes, higher marginal income taxes, or a national sales tax are all options the Obama administration can choose from. For now, it appears it’s choosing none of these, and instead selling more bonds to the public, foreigners, and the Fed, increasing the moneys supply in the hope that households and firms begin spending once more. The path towards fiscal discipline is a hard one to get started on, especially during a recession when no new taxes are politically viable.

Discussion Questions:

1. What make’s a sales tax regressive if everyone has to pay, say, 10% on top of the regular sales price of a good or service?
2. How does the US government finance its massive budgets when its revenue from taxes don’t even come close to equaling the amount of spending?
3. Why is it important for a country, in the long-run, to achieve a balnced budget?
4. What would you prefer to do: pay a higher income tax or a higher sales tax? What are the pros and cons of direct versus indirect taxes?
