In the seemingly endless and currently ongoing debate over the role of the government in the macroeconomy, there are two main camps: Those who think the governments of the developed economies have not done enough to get their economies out of recession, and those who think they have already done too much, and therefore need to start rolling back stimulus and reducing deficits.

At the heart of this debate are the two macroeconomic schools of thought, the  Keynesian demand-side theories and the classical, supply-side theories. Two intellectuals have emerged in the last several years representing the two sides of the macroeconomic debate. On the demand-side, representing the Keynesian school of thought, is 2008 Nobel Prize winning economist Paul Krugman. Representing the classical, supply-side school of thought is Harvard economic historian Niall Ferguson. These two have squared off in many forums over the last three years, Krugman arguing for more and continued fiscal stimulus to prop up and increase demand in the economy, Ferguson arguing for smaller deficits, lower taxes and less government spending to increase private sector confidence and thereby supply in the economy.

During our long summer break the two squared off once again in the aftermath of a G20 meeting in which the governments of several major economies from Europe and North America announced plans to begin rolling back the stimulus spending they embarked on throughout 2008 and 2009. The reason for increased “austerity measures” (policies that reduce the budget deficit and slow the growth of national debt), argue global leaders, is to reduce the chances of more countries experiencing debt crises like that experienced in Greece this spring.

International investors realized earlier this year that Greece’s budget deficits were a much larger percentage of its GDP than previously thought, and very quickly decided that Greek government bonds were an unsafe investment. Almost overnight the cost of borrowing in Greece shot up above 20%, bringing investment in the economy to a halt and forcing the government to cut its budget, leading to higher unemployment and reduced social benefits for the people of Greece.  If investors were to look at the growing budget deficits in other developed countries and  then suddenly lose faith in other government’s ability to pay back their debts, then a similar crisis could occur in much larger economies, including the UK, Germany and the United States. Hence these country’s apparent desire to begin reducing deficits and rolling back stimulus spending; measures that may just plunge these economies into an even deeper recession than that which they have experienced over the last two years.

The videos below show the leading intellectuals on both sides of the stimulus/austerity debate presenting their arguments. Below each video are discussion questions to help guide your understanding of their views. Watch the videos and respond to the discussion questions in the comment section below.

Discussion Questions:

1. What are the two “profoundly different views of economics” that are being tested as governments begin rolling back the fiscal stimulus packages of the last two years?
2. What are three characteristics of an economy in a “depression” according to Krugman?
3. What is “budget austerity” and why does Krugman think this should not be the first priority of policymakers in the G20 nations?
4. Why is deflation dangerous according to Krugman?
5. What is the additional annual cost to the US government of borrowing and spending an additional trillion dollars now? What is the potential additional benefit of more stimulus?

Video 2 - Ferguson argues for austerity and “fiscal regime change”:

Discussion Questions:

1. Why might the US have to pass spending cuts and tax increases to maintain its “credibility in international bond markets”?
2. Why would fiscal tightening “choke off the recovery”?
3. How is the financial crisis in Europe a warning to the US?
4. How could the “costs” exceed the “benefits” of deficit financed expansionary fiscal policy.
5. Ferguson proposes a new type of policy that “boosts confidence”. Why will expansionary fiscal and monetary policies fail if private sector confidence remains depressed?

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?

Deflation or Inflation:Watch the video below, see if gives you any clues as to the causes and effects of deflation. What do you think John Maynard Keynes would say in response to the deflationary fears expressed in the Economist article?
