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?
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 leaders of the G20 countries gathered in Pittsburgh on 24 and 25 September 2009 to discuss a range of economic issues. These included co-ordinated action to ensure the world economy maintained its fragile recovery; reforming the IMF; agreeing action on bank regulation and the limiting of bankers’ bonuses.
The following is a selection of podcasts and videos looking at various aspects of the summit and its outcomes. The first one, to set the scene, is a webcast from the IMF looking at the state of the world economy and the role of macroeconomic policy and banking regulation. There are also some articles looking at the achievements of the summit. (See here for G20 draft communiqué)

Questions
- Explain the issues faced by the G20 countries.
- To what extent is trying to reach international agreement on co-ordinated action a prisoner’s dilemma game? Is it, nevertheless, a positive sum game?
- What was agreed at Pittsburgh and to what extent will it lead to action as opposed to being mere rhetoric?
- The G8 is effectively dead, having being replaced by the G20, plus Spain, The Netherlands and various international bodies, such as the IMF. What are the advantages and disadvantages of this move?
Up until a year ago, milk and cheese prices were soaring woldwide (see Cheddar – the king of cheeses at £2000 per tonne). A surging world economy and rapidly growing demand from China and India were driving up commodity prices, including milk and milk-based producs. In the UK, average farmgate prices for milk had risen from 19 pence per litre (ppl) in 2006 to 27.4ppl by October 2008 (see here for data). Since then, however, as the global economy has plunged into recession, milk prices have fallen. By September 2009, the farmgate price had fallen by over 18 per cent to around 22.4ppl. With rising costs for fuel and cattle feed, many dairy farmers are now making a loss and are either quitting, or considering quitting, the industry.
It’s a similar story in Europe, North America and other dairy producing regions of the world. In Europe “the mood is turning sour. Last week 300 tractors dragged milk containers over fields in southern Belgium, dumping a day’s worth of production (see video). Similar protests were made in Germany, France, the Netherlands and Luxembourg. The crisis has driven many EU farmers into a ‘milk strike’, with thousands refusing to deliver to the industrial dairy conglomerates that produce everything from skimmed milk to processed cheese.”
So is this just market forces in action and will prices rise again as the world economy recovers? Or is it a reflection, in part, of the monopsony power of the supermarkets and the milk processing industry? The following articles look at the issues, both in the UK and the rest of Europe and in the USA.

Questions
- For what reasons are many dairy farmers now making a loss?
- For what reasons has the power balance in the wholesale milk market shifted towards milk purchasers (such as supermarkets) and away from farmers?
- How would a phased liberalisation of EU milk production help the UK’s dairy farmers?
- Discuss the likely effectiveness of the European Commission’ proposed measures to help dairy sector in short, medium and long term.
- What is likely to happen to milk prices over the next two years and what will be the likely effect on supply? Explain your answer and consider the relevance of price elasticity of supply.
- “Agriculture officials and farmers in Vermont, New Hampshire and Massachusetts have launched a program called Keep Local Farms. … Organizers say they hope to appeal to consumers’ growing taste for local foods” (see final linked article above). What determines the likely effectiveness of such ‘buy local’ movements? What incentives are there for people to buy local? If countries in general encourage people to buy local, is this a zero sum game? Explain.
