Category: Economics: Ch 19

Whilst some economists predicted the banking crisis of 2007/8 and the subsequent global recession, many did not. Was this a failure of macroeconomics, or at least of certain macroeconomic schools of thought, such as New Classical economics? Or was it a failure to apply the subject with sufficient wisdom? Should the subject be radically rethought, or can it simply be amended to take into account aspects of behavioural economics and a better understanding of systemic risk?

The four linked articles below from The Economist look at the debate and at the whole state of macroeconomics. The other articles pick up some of the issues.

Will the ‘crisis in macroeconomics’ lead to a stronger subject, more able to explain economies in crisis and not just when they are working well? Will a new consensus emerge or will economists remain divided, not only about the correct analysis of how economies work at a macro level, but also about how to tackle crises such as the present recession?

Questions

  1. Distinguish between ‘freshwater’, ‘saltwater’ and ‘brackish’ macroeconomics.
  2. Explain why economists differ over the efficacy of fiscal policy in times of recession. To what extent does the debate hinge on the size of the multiplier?
  3. Why is the potential for macroeconomics higher now than prior to the recession?
  4. What is meant by the ‘efficient market hypothesis’? How did inefficiencies in financial markets contribute to the banking crisis and recession?
  5. Should economists predict the future, or should they confine themselves to explaining the present and past?

The current recession has seen the re-emergence of many of the intellectual battles fought amongst economists between the two worlds wars and again from the 1960s to the 1980s. The current debate has hinged around the appropriate policy response to the current recession. Is the solution a Keynesian one of stimulating aggregate demand; or is it a new classical one of keeping public spending under control to make room for private spending and to allow the market to function to best effect? And what about banking reform? What are the arguments here? The following articles by Lord Skidelsky examine the debate.

Questions

  1. Explain the ways in which economics is (a) similar to and (b) different from the natural sciences.
  2. For what reasons would new classical economists criticise the fiscal stimulus packages pursued by many countries in the past few months?
  3. Under what circumstances would a fiscal stimulus crowd out private spending? Do these circumstances apply (a) today; (b) over the next two years?
  4. Why may crowding out in practice depend on issues of confidence?
  5. What ‘Keynesian lessons’ have been learned from the banking crisis and recession?

The early part of the current recession, dating from April 2008, had much in common with the Great Depression dating from June 1929. But the Great Depression lasted three years. So does this grim prospect await the world this time round? Or have we learned the lessons of the past and will the policies of giving economies a large fiscal stimulus, combined with bank rescues and quantitative easing, help to pull the world out of recession this year? The following articles look at the issues.

Questions

  1. Why may the past be a poor guide to the present and future?
  2. What dangers are there from the policies of expanding aggregate demand through fiscal and monetary policies?
  3. Explain why the ‘race to full recovery is likely to be long, hard and uncertain.

Economists never like to use simple words when there are more complex ones available! So, the new term for printing money is ‘quantitative easing’. This refers to deliberate increases in the money supply aimed at preventing deflation. The real concern is whether quantitative easing will stoke up inflationary pressures for the future – the balance between inflation and deflation is a fine line to tread. Quantitative easing becomes necessary when there is danger of deflation and interest rates have already been cut as far as is possible.

Another problem, in the short term, is that an increase in the monetary base may have little effect on broader money (M4 in the UK) if people do not want to borrow and thus credit creation is limited.

The articles below all look at various different aspects of quantitative easing.

Questions

  1. Define the term ‘quantitative easing’.
  2. Explain the mechanism by which the monetary authorities can implement a policy of quantitative easing.
  3. Discuss the relative effectiveness of cuts in interest rates and quantitative easing to boost aggregate demand in a recession.
  4. Analyse the impact on an economy of a prolonged period of deflation.

Sir Alan Walters, one of Mrs Thatcher’s key economic advisers, has died at the age of 82. Though he always tried to shun media attention, Sir Alan attracted a considerable amount of it when he clashed publicly with the then Chancellor, Nigel Lawson, over the Exchange Rate Mechanism (ERM). When faced with the choice from Nigel Lawson that either Alan Walters went or he did, Mrs Thatcher famously chose her adviser over her Chancellor. This lent Sir Alan a degree of infamy in economic circles and he is perhaps known best as one of the most influential monetarists of the period. Sir Alan was an early advocate of money supply targeting and always argued that the money supply should not be manipulated for political reasons. His advice was also key in the budget of 1981 which raised taxes in the middle of a recession, something that in this current recession would appear to be unthinkable.
