With more than four million Spanish people out of work this week, the eighth largest economy in the world finds itself once more in a perilous position. In the last twelve months the number of unemployed people in Spain has doubled. Spain now has as many unemployed people as France and Italy combined, and the unemployment rate is nearing the historic highs of 1993.

The type of unemployment in an economy can be classified in different ways. The main types are cyclical or demand deficient unemployment but other forms exist such as real-wage unemployment and equilibrium unemployment. Some economists also refer to unemployed people as structural, frictional, seasonally or cyclically unemployed.

From the graph below we can see that unemployment in Spain has been high for at least the last 20 years, compared to other countries within the European Union.

Source: OECD Factbook 2009: Economic, Environmental and Social Statistics

The cause of growing Spanish unemployment in 2008 to 2010 is related to the collapse of the domestic building boom and the wider global recession. In 2006, Spain enjoyed low interest rates and therefore cheap loans, this allowed developers to build new apartment blocks, houses and commercial buildings with a relatively low cost of borrowing. Spanish people could afford mortgages at low interest rates and therefore purchased houses contributing to the building boom. However, when the flow of “cheap money” ran out in mid 2008 the building stopped and the flow on effects of spending dried up. Falling tourism receipts and less foreign investment have also exacerbated the issue leading to unemployment doubling between 2008 – 2010.

We can classify the form of unemployment, illustrated in the Spanish example as demand-deficient unemployment. It is related to a downturn in the economic cycle. This concept is explained below.

#3aEffects and Solutions

The social and economic impacts of 20.7% unemployment are obvious, but the solutions are less so. Climbing unemployment creates two evils; falling tax revenue as workers no longer earn wages and the increased burden of paying benefits to the four million unemployed citizens. In addition, a series of social problems are often intertwined with high unemployment, these include depression; lose of skills, poverty and higher crime rates. Spain therefore has a few problems to solve this summer. Whilst Spanish people may enjoy a summer by the beach, and a glass of sangria, the government will be hitting the books to find a solution to the problem. Here are a few suggests to get the politicians thinking.

• Use fiscal stimulus to boost consumer and government spending, thereby increasing the demand for jobs. Spain could plan for a budget deficit (expansionary fiscal policy) and fund spending increases though increased government borrowing. Spain’s current level of public debt is 67% of GDP, which is well below stricken Greece at 124%. However, Spain now has to borrow money from international bond markets, which are skeptical about Spain’s ability to pay back this debt. This is despite assurances and favourable rates offered from the European Union this week. Increasing government debt in a period of European financial crisis is a risky option.

• Use loose monetary policy (lowering central bank interest rates) to encourage Spanish people to increase their consumer spending through increased borrowing. If you understand the complexities of the European Union, you understand that all 21-member countries use the same currency and follow the lead of one central bank. Despite one country wishing to lower interest rates, other countries may think differently. Europe can be compared to a train rolling along on a set of rails, with 21 separate carriages. Each European country must follow behind the big engine, there is no room to deviate from the central banks interest rates and all of the countries must move together. Many people have wondered how long the European train would run, before one of the carriages derailed.

• Force Spanish firms to employ more people. Firms have no requirement to hire more people. They may choose to employ more people but will logically offer everyone lower wages to maintain profitability.

• Use supply side policies to bring greater efficiencies to firms though increased on the job training and worker education. This is a long-term solution, which will require large structural adjustments, how Spain produces goods and services and exactly what is does produce. A startling statistic is that the average Spanish university graduate will find their first job at the age of 27, long after they have graduated.

Discussion Questions:

1. How do economists measure unemployment?
2. Explain the causes of increased unemployment in Spain?
3. Explain in a few sentences how expansionary fiscal policy could reduce the rate of unemployment?
4. How could supply side policies be used to reduce the level of unemployment in Spain?

Argentina’s reserves and its debts: Central Bank robbery | The Economist

I received the following email from an Econ teacher who wonders if I had any insight on a question posed by one of his students:

The email reads: “I have alittle query i was hoping you could help clear up for me..a year 13 student has asked a question relating to Argentina’s prime minister, Cristina Fernandezde De Kirchner’s, decision to sell the central bank’s dollar reserves to fund part of the country’s decifit against the advice of the director of the central bank who resigned.”

The student’s question is on the following passage from the Economist article above:

Fernández (Argentina’s president”) justified her raid on the reserves by saying that the Central Bank had more than it needed, because they exceeded the size of the monetary base. Economists disagree about what is an appropriate target for the reserves, but Mr Redrado’s view is that a highly dollarised emerging economy like Argentina’s needs an abundance of Treasury bonds (the form in which most reserves are held) as insurance. Even if Ms Fernández might find support from some economists for her argument, her plan to swap the dollar reserves for a non-transferable government bond would not.

The student’s question is: “I do not know what a monetary base is, nor why Argetina needs treasury bonds.”

This article really caught me off guard at first as well. One thing I love about the Economist newspaper is its use of economic jargon that requires a real understanding of the subject to be able to interpret. The first time I read the article, I will be honest I was completely confused as to what the Argentinean president was up to. But after some reflection and rough sketches of graphs on scrap paper, I think I have “translated” the article’s jargon into plain English.

Below is my reply to the teacher and his student:

Hello,

The president of Argentina wants to sell the country’s US dollar reserves, which are held in the form of US treasury bonds, and then use the US dollars she receives to buy Argentinean government bonds in order to finance her own government’s budget deficit. In essence she wants to swap Argentina’s central bank reserves of US debt (considered a very stable and safe asset due to America’s low inflation rate and relative solvency of the US government) for Argentinean government debt (less stable and safe, especially in the wake of the country’s 2002 default on its debt). Argentina’s central bank would then hold fewer transferable, stable US bonds and more “non-transferable”, Argentinean government bonds. And since the bonds represent Argentina’s government debt, the country as a whole reduces its assets and increases its liabilities.

It is important for a developing country like Argentina to keep large reserves of US dollar-denominated assets (i.e. US treasury bonds) in reserve in order to assure foreign investors that the country would be able to stabilize its currency’s value in the face of a currency crisis such as that which Argentina experienced in 2001-2002. If the value of the peso began to decline on foreign exchange markets (due, for instance, to a decline in international investor confidence in the government’s ability to pay the interest on its foreign debt or inflation fears caused by excessive monetary growth or government spending) then the central bank could use its large dollar reserves to intervene in the forex market and stabilize the value of the peso, reestablishing investor confidence and maintaining the government’s ability to attract foreign creditors in the Argentinean bond market. A collapse of the peso would have ripple effects throughout Argentina, driving up imported products and raw materials and causing spiraling inflation, forcing the government to print more money to finance its budget in the face of falling demand for its debt in domestic and international bond markets.

Argentina must be sure to keep its balance sheet (i.e. its liability to asset ratio) in check. Its assets are US government bonds, its liabilities are the Argentinean bonds it issues to finance its budget deficits. If this ratio become too heavy on the liability side, foreign investors and speculators will lose confidence in the both peso and the Argentinean government’s solvency and dump their holdings of Argentinean currency, assets, and bonds, driving interest rates through the roof and the exchange rate through the floor, grinding the economy to a halt.

The article says,

Argentina’s economy is on course to rebound this year and grow at 3-5%. But the government is spending money so fast that this growth will not finance current spending on its own, says Daniel Marx, a former finance minister. Ordinarily, a government faced with a shortfall would turn to domestic and international bond markets. But this has been difficult since Argentina defaulted in 2002.

The country cannot count on private creditors to make up its budget shortfall, so the president is planning to finance her country’s deficit by buying Argentinean bonds with the country’s own US dollar reserves. Such behavior concerns economists because it could send a message to international investors that the country is on the path towards another unsustainable build-up of debt that could culminate in another default and economic collapse. The article is a word of caution to the president that all leaders should heed: balanced budgets are a good idea, and debt is dangerous!

Econstories.tv – A new resource for Econ teachers and students, from Russ Roberts and John Papola

The long awaited rap video from George Mason University’s Russ Roberts featuring the theories of John Maynard Keynes and F. A. Hayek has been released at last!

We’ve heard some decent Econ raps before (remember “Demand, Supply” by Rhythm, Rhyme, Results?) But this song covers all bases in the predominant macroeconomic schools of thought. Keynes and Hayek are brought back to life and their theories pitted against one another in an all out liquor fueled debate on the streets of New York City.

The video was just released this week. It is packed full of theory from the Classical, supply-side school of macroeconomics (represented by Hayek) and the demand-side school (represented, of course, by Keynes). The video includes cameos from Fed chairman Ben Bernanke and Treasury Secretary Tim Geithner, whose role as bartenders filling Keynes glass reflects their role in the real economy at keeping the money supply and government spending at high levels, fueling economic booms and the eventual busts that result.

Stay tuned to this blog for more feedback on the video, including some graphical analysis and discussion questions for Macro teachers to use in class!

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?

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?

Harvard Economist Niall Ferguson appeared on CNN’s GPS with Fareed Zakaria over the weekend. Ferguson has stood out among mainstream economists lately in his opposition to the US fiscal stimulus package, an $880 billion experiment in expansionary Keynesian policy. While economists like Paul Krugman argue that Obama’s plan is not big enough to fill America’s “recessionary gap”, Ferguson warns that the long-run effects of current and future US budget deficits could lead the US towards economic collapse. This blog post will attempt to explain Ferguson’s views in a way that high school economics students can understand.

Government spending in the US is projected to exceed tax revenues by $1.9 trillion this year, and trillions more over the next four years. An excess of spending beyond tax revenue is known as a budget deficit, and must be paid for by government borrowing. Where does the government get the funds to finance its deficits? The bond market. The core of Ferguson’s concerns about the future stability of the United States economy is the situation in the market for US government bonds. According to Ferguson:

One consequence of this crisis has been an enormous explosion in government borrowing, and the US federal deficit… is going to be equivelant to 1.9 trillion dollars this year alone, which is equivelant to nearly 13% of GDP… this is an excessively large deficit, it can’t all be attributed to stimulus, and there’s a problem. The problem is that the bond market… is staring at an incoming tidal wave of new issuance… so the price of 10-year treasuries, the standard benchmark government bond… has taken quite a tumble in the past year, so long-term interest rates, as a result, have gone up by quite a lot. That poses a problem, since part of the project in the mind of Federal Reserve Chairman Ben Bernanke is to keep interest rates down“

There’s a lot of information in Ferguson’s statements above. To better understand him, some graphs could come in handy. Below is a graphical representation of the US bond market, which is where the US government supplies bonds, which are purchased by the public, commercial banks, and foreigners. Keep in mind, the demanders of US bonds are the lenders to the US government, which is the borrower. The price of a bond represents the amount the government receives from its lenders from the issuance of a new bond certificate. The yield on a bond represents the interest the lender receives from the government. The lower the price of a bond, the higher the yield, the more attractive bonds are to investors. Additionally, the lower the price of bonds, the greater the yield, thus the greater the amount of interest the US government must pay to attract new lenders.

Ferguson says that the price of US bonds has “taken a tumble”. The increase of supply has lowered bond prices, increasing their attractiveness to investors who earn higher interest on the now cheaper bonds. Below we can see the impact of an increase in the quantity demanded for government bonds on the market for private investment.

Financial crowding-out can occur as a result of deficit financed government spending as the nation’s financial resources are diverted out of the private sector and into the public sector. Granted, during a recession the demand for loanable funds from firms for private investment may be so low that there is no crowding out, as explained by Paul Krugman here.

But crowding out is not Ferguson’s only concern. The increase in interest rates caused by the US government’s issuance of new bonds could lead to a decrease in private investment in the US economy, inhibiting the nation’s long-run growth potential. But the bigger concern is one of America’s long-run economic stability. If the Obama administration does not put forth a viable plan for balancing its budget very soon, the demand for US government bonds could fall, which would further excacerbate the crowding-out effect, and eliminate the country’s ability to finance its government activities. In other words, such a loss of faith could plunge the United States into bankruptcy.

Fareed Zakaria asks Ferguson:

“Is it fair to say that this bad news, the fact that we can’t sell our debt as cheaply as we thought, overshadows all the good news that seems to be coming?”

Ferguson’s reply:

The green shoots that are out there (referring to the phrase economists and politicians have been using to describe the signs of recovery in the US economy) seem like tiny little weeds in the garden, and what’s coming in terms of the fiscal crisis in the United States is a far bigger and far worse story.

Finally Fareed asks the question everyone wants to know:”What the hell do we do?”

Ferguson:

One thing that can be done very quickly is for the president to give a speech to the American people and to the world explaining how the administration proposes to achieve stabilization of American public finance… the administration doesn’t have that long a honeymoon period, it has very little time in which it can introduce the American public to some harsh realities, particularly about entitlements and how much they are going to cost. If a signal could be sent really soon to the effect that the administration is serious about fiscal stabilization and isn’t planning on borrowing another $10 trillion between now and the end of the decade, then just conceivably markets could be reassured.

Ferguson is saying that only if the Obama administration begins taking serious steps towards balancing the US government’s budget can it hope to stave off an eventual loss of faith among America’s creditors (and thus a fall in demand for US bonds). It will be a while before tax revenues are high enough to finance the US budget. But if the country does not begin working towards such an end immediately, it may find itself unable to raise the funds to pay for such public goods as infrastructure, education, health care, national defense, medical research, as well as the wages of the millions of government employees. In other words, the US government could be bankrupt, and its downfall could mean the end of American economic power.

The power of the bond market should not be underestimated. America’s very future depends on continued faith in its financial stability and fiscal responsibility.

Discussion Questions:

1. Why do you think the US government has such a huge budget deficit this year? ($1.9 trillion) Previously, the largest budget deficit on record was only around $400 billion.
2. How does the issuance of new bonds by the US government lead to less money being available to private households and firms?
3. Do you think investors will ever totally lose faith in US government bonds? Why or why not?
4. In what way is the government’s huge budget deficit a “tax on teenagers”? In other words, how will today’s teenagers end up suffering because of the federal budget deficit?

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?

Liquidity preference, loanable funds, and Niall Ferguson (wonkish) – Paul Krugman Blog – NYTimes.com

Below is the loanable funds market at its current equilibrium, according to Krugman (I is investment demand for funds, S is the supply of loanable funds):

In Krugman’s words:

In effect, we have an incipient excess supply of savings even at a zero interest rate. And that’s our problem.

So what does government borrowing do? It gives some of those excess savings a place to go — and in the process expands overall demand, and hence GDP. It does NOT crowd out private spending, at least not until the excess supply of savings has been sopped up, which is the same thing as saying not until the economy has escaped from the liquidity trap.

In AP Macroeconomics, we teach that deficit-financed government expenditure decreases the supply of loanable funds as savers take their money out of commercial banks and invest in the bond market due to the attractive interest rates on government debt. Less funds available for the private sector drives up interest rates and crowds out private investment.

If the economy is producing close to the full-employment level and interest rates are positive, the decrease in supply of loanable funds can indeed drive up equilibrium interest rates and lead to the “crowding-out” of private investment. Krugman points out in this article that when the economy is at the “zero-bound” (i.e. when nominal interest rates are as low as they can go) and the quantity supplied of savings is still greater than the quantity demanded for investment, the government can effectively borrow from the public, decreasing the supply and correcting the surplus of savings without driving up interest rates in the private market. Put another way, the equilibrium interest rate is below zero, but the “zero-bound” acts as a price floor in the loanable funds market, resulting in a surplus of savings.

Government borrowing crowding out private investment is not something we can worry about during a recession, when low confidence and expectations have driven the supply of savings up and the demand for investment down. Public spending will divert funds from the private sector to the public sector, that’s true. But in today’s case, savings are sitting idle in the private sector, so government borrowing is putting those fund to use when the private sector has failed to do so.

Discussion Questions:

1. Why does the supply of loanable funds (S in the graph above) slope upwards? Why does the demand for loanable funds (I in the graph) slope downwards?
2. Deficit financed government spending decreases the supply of loanable funds. Why?
3. Crowding-out is not the only possible down-side of deficit spending by the government. What are some other long-term effects of governments running budget deficits year after year?

The Fed should focus on deflation | The greater of two evils | The Economist

Deflation: a decrease in the general price level of goods and services of an economy. Sounds great, right? Lower prices mean the purchasing power of our income increases, making the “average” person richer! On the surface, it could be concluded that deflation may actually be a good thing. And in some cases, it is!

If prices of goods are falling because of major technological advances (think of the price of cell phones and laptop computers over the last 20 years) or because of massive improvements in the productivity of labor and capital (think of the price of manufactured consumer goods during the Industrial Revolution), then deflation could be considered a sign of healthy economic growth. Put in terms an IB or AP Economics student should understand, a fall in prices caused by an increase in a nation’s aggregate supply is good, since it is accompanied by greater levels of employment and higher real incomes. But if the fall in prices is caused by a decline in spending in the economy (in other words, by a decrease in aggregate demand), the consequences can be catastrophic.

It just so happens that the United States, Great Britain, and my own home of Switzerland are all faced with demand-deficient deflation at this very moment. I’ll allow the Economist to elaborate:

…With unemployment nearing 9% (in the United States), economic output is further below the economy’s potential than at any time since 1982. This gap is likely to widen. House prices are not part of America’s inflation index but their decline is forcing households to reduce debt , which could subdue economic growth for years. As workers compete for scarce jobs and firms underbid each other for sales, wages and prices will come under pressure.

So far, expectations of inflation remain stable: that sentiment is itself a welcome bulwark against deflation. But pay freezes and wage cuts may soon change people’s minds. In one poll, more than a third of respondents said they or someone in their household had suffered a cut in pay or hours…

Does this matter? If prices are falling because of advancing productivity, as at the end of the 19th century, it is a sign of progress, not economic collapse. Today, though, deflation is more likely to resemble the malign 1930s sort than that earlier benign variety, because demand is weak and households and firms are burdened by debt. In deflation the nominal value of debts remains fixed even as nominal wages, prices and profits fall. Real debt burdens therefore rise, causing borrowers to cut spending to service their debts or to default. That undermines the financial system and deepens the recession.

From 1929 to 1933 prices fell by 27%. This time central banks are on the case. In America, Britain, Japan and Switzerland they have pushed short-term interest rates to, or close to, zero…

…inflation is easier to put right than deflation. A central bank can raise interest rates as high as it wants to suppress inflation, but it cannot cut nominal rates below zero… In the worst case, rising debts and defaults depress growth, poisoning the economy by deepening deflation and pressing real interest rates higher….Given the choice, erring on the side of inflation would be less catastrophic than erring on the side of deflation.

Discussion Questions:

1. Deflation poses several threats to an economy that is otherwise fundamentally healthy, such as the United States’. What are some the threats posed by deflation?
2. The expectation of future deflation can have as equally devastating effect. Why is this?
3. What evidence does the article put forth that an economy experiencing deflation may eventually “self-correct”, meaning return to the full employment level of output in the long-run?
4. Why don’t governments and central banks just sit back and let the economy self-correct? In other words, why are fiscal and monetary policies being used so aggressively by the US, Great Britain and Switzerland during this economic crisis?
