The following two clips look at John Maynard Keynes’s contribution to macroeconomics and whether his theories have been proved to be correct by the events of the past two years.
“What would John Maynard Keynes make of the financial crisis and the credit crunch?” In the first clip, “Author Peter Clarke, former professor of modern British history at Cambridge University, and the former Conservative chancellor Lord Lamont consider whether Keynes’s ideas were twisted by modern politicians to support their desires to run big spending deficits.”

Questions
- How is the recent crisis and recession similar to and different from the Great Depression of the inter-war period?
- Can recent fiscal policies adopted around the world be described as Keynesian?
- How would a government of a Keynesian persuasion attempt to manage the move from recession to economic growth and deal with the problem of mounting public-sector debt?
According to Brad DeLong, professor of economics at the University of California at Berkeley, if we are to get a full understanding of the financial crisis and recession of the past two years, we need to take a historical perspective. In the following article from The Economic Times of India, he argues that modern macroeconomists need to learn from history if their assumptions and models are to be relevant and predictive.

Economic History and Modern Macro: What Happened? (30/9/09)
Questions
- According to Narayana Kocherlakota, most macroeconomic models “rely on some form of large quarterly movements in the technological frontier. Some have collective shocks to the marginal utility of leisure. Other models have large quarterly shocks to the depreciation rate in the capital stock (in order to generate high asset price volatilities)…”. How could these models explain business cycles? Would you classify them as ‘real business cycle theories’: i.e. as ‘supply-side’ explanations?
- How does Brad deLong explain recessions?
- Why does a change in the velocity of circulation of money contribute to a crash?
- What are the strengths and limitation of using economic history to understand the current crisis?
In an attempt to stave off recession, countries around the world have made extensive used of fiscal stimuli. Combinations of tax cuts and increases in government expenditure have been used to boost aggregate demand and thereby to halt falling national income. “The G20 group of economies … have introduced stimulus packages worth an average of 2% of GDP this year and 1.6% of GDP in 2010.”
But how much will national income respond to a particular fiscal stimulus? It depends on the size of the fiscal multiplier for each type of government expenditure increase or tax cut. The bigger the multiplier for each expansionary measure, the more will national income rise. Clearly, to estimate the effects of their fiscal measures, governments would very much like to know the size of these multipliers. But that’s not so easy, as the following article from The Economist explains.
Much ado about multipliers The Economist (24/9/09)
Questions
- What are the formulae for (a) the government expenditure multiplier; (b) the tax multiplier?
- Why is the value of the multiplier likely to vary with the type of government expenditure increase or tax cut that is used? Which types of government expenditure increases and tax cuts are likely to have (a) the largest effects; (b) the fastest acting effects?
- Why is the size of any particular fiscal multiplier difficult to predict? How do expectations impact on the size of the multiplier?
- Under what circumstances are fiscal measures likely to be ‘crowded out’? How can monetary policy be used to prevent, or at least minimise, crowding out?
The blame for the global economic crisis has been placed on many different people, but one area that has been severely criticised for the extent of the financial crisis is banking and financial regulation (or a lack thereof). One thing that has been repeated is that we must learn from our mistakes and therefore tighten financial regulation on a global scale. The Institute for Public Policy Research (IPPR) says the ‘rapid return to the City’s bonus culture shows that real reform has been “very limited”’. France in particular is arguing for tighter financial regulation, including curbing bankers’ bonuses to avoid a repeat of last year’s meltdown. However, it is meeting resistance from the UK and USA. Indeed, some banks appear to have extended their bonus culture.
As the banking sector slowly begins to recover, there is concern that few changes have been made to ensure that there is no repeat of the recent crisis. Banks have been warned that they should not resume taking risks, as they did before, as future bailouts by the government (and hence the taxpayer) will not keep happening. The European Union has now unveiled plans for new ‘super-regulators’, but only time will tell whether they will be a success.

Questions
- What are the advantages and disadvantages of tighter regulation of the financial sector for (a) the UK and (b) the global economy? What forms should such regulation take?
- What are the arguments for and against imposing a statutory capital adequacy ratio on banks that is substantially higher than the ratios with which banks have been operating in recent years?
- In what ways was a lack of financial regulation responsible for the financial crisis?
- Why is the continuation and possibly growth of the bonus culture a potentially dangerous issue for any future crisis?
- The articles talk about ‘lessons being learned’. What lessons are they referring to?
- The financial crisis has affected everyone in some way. What has been the impact on taxpayers?
Oil affects our everyday lives. Whether it’s to heat your house, to run your car or to work out production costs, the price of oil is important. Commodity prices are determined by the interaction of demand and supply and oil prices are no different. As demand and supply for products and for oil itself change, so will the price of oil. However, any changes in the price of this valuable commodity will also have effects on macroeconomic variables, such as inflation. From a high of $147 (£90) per barrel in July 2008, it fell to $30 by the end of the year. But since then it doubled to reach $60 by May and has been around the $70 mark since.
How have these fluctuations affected the economy? Should more be invested in extraction? Extracting oil is an expensive process and requires huge investment, which is problematic given the current recession and various funding issues. The following articles consider this problem, as well as the impact it is likely to have on our economic recovery.
