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?
Adair Turner, chairman of the Financial Services Authority, the UK’s financial sector regulator, has proposed the possible use of Tobin taxes to curb destabilising financial transactions. The late James Tobin, winner of the 1981 Nobel prize in Economics, argued that a very small tax (between 0.1 and 1 per cent) should be imposed on foreign exchange transactions to dampen destabilising foreign currency speculation and thereby reduce exchange rate fluctuations. Lord Turner’s proposal would apply to a whole range of financial transactions, putting some friction in these very volatile and often highly leveraged markets. Such a tax would discourage some of the riskier and more exotic transactions on which many of the bonuses of bankers have been based.
Not surprisingly, his proposals have been met with derision by many in the banking sector. Many politicians too have been critical, arguing that the taxes will divert financial business away from London to other financial centres around the world. And yet, at the G20 summit in Pittsburgh on 24/25 September, both the German chancellor, Angela Merkel, and the French president, Nicolas Sarkozy, argued in favour of such taxes. The result was that the IMF was asked to investigate the practicality of using Tobin taxes on financial transactions as a way of reining in more risky behaviour. A week later the IMF, while ruling out a simple Tobin tax, came out in favour of taxes on the global financial sector designed to reduce speculation.
So who is right? The following articles look at the issues.

Questions
- Explain how a Tobin tax could be used to reduce destabilising speculation without preventing markets movement to longer-term equilibria.
- How might the use of a Tobin tax on financial transactions help to curb some of the ‘excessive rewards’ made from financial dealing.
- How do Lord Turner’s proposals differ from those of President Sarkozy?
- Examine the advantages and disadvantages of using a Tobin tax on financial transactions. How might the disadvantages be reduced?
- Explain what Lord Turner means by “the financial services industry can grow to be larger than is socially optimal”. How would you define ‘socially optimal’ in this context?
From October 2007 to March 2009, stock markets around the world fell massively. In the UK, the FTSE 100 fell from a peak of 6752 on 15 October 2007 to a trough of 3461 on 9 March 2009 (a fall of 49 per cent). By the end of August 2009 it had reached 4944 (a rise since March of 43 per cent). Does this mean that the March value represented an over-correction downwards? Did the subsequent rise represent an over-correction upwards? Are stock markets about to plummet? The following two articles reflect on the past and look into the future!

Questions
- What is meant by the ‘efficient (capital) market hypothesis’?
- If stock markets are overvalued, does this mean that they are inefficient?
- Why might (a) stock markets plummet in the near future; (b) carry on rising? Why don’t the ‘experts’ know which will happen?
- Explain why markets may over-shoot their long-term equilibrium value?
Many primary commodity prices have fallen during the recession, but have recovered somewhat as the recession has bottomed out and hopes of a recovery have grown. So what will happen to commodity prices over the next few months and beyond, and what will determine the size of the price changes? The following linked articles look at these questions.

According to both the Lloyds Banking Group’s Halifax price index and the Nationwide Building Society, the annual rate of decline in house prices is reducing and the three-monthly figures now show a small increase in house prices. So does this mean that the housing market is now recovering?
The Centre for Economics and Business Research (CEBR) is forecasting a rise of 2 per cent in house prices between the end of 2009 and the end of 2010. Other forecasters are predicting higher price increases. Part of the reason lies on the demand side, but part also lies on the supply side. The following linked articles explore these determinants of demand and supply.

Questions
- Identify the determinants of demand and supply that are likely to affect the price of houses in the coming 12 months. Use a diagram to illustrate the effect on house prices.
- What is the relevance of the price elasticity of demand and supply of houses in explaining the magnitude of the predicted price movements?
- What effect is speculation likely to have on the price of houses?
- Assess the suitability of property taxes as a means of stabilising house prices (see the final Guardian article and the Toby Lloyd article).
