Should economists have foreseen the credit crunch? A few were warning of an overheated world economy with excessive credit and risk taking. Most economists prior to 2007/8, however, were predicting a continuation of steady economic growth. Inflation targeting, fiscal rules and increasingly flexible markets were the ingredients of this continuing prosperity. And then the crash happened!
So why did so few people see the downturn coming? Were the models used by economists fundamentally flawed, or was it simply a question of poor assumptions or poor data? Do we need a new way of modelling the economy, or is it simply a question of updating theories from the past? Should, for example, models become much more Keynesian? Should we abandon the new classical approach of assuming that markets are essentially good at pricing in risk and that herd behaviour will not be seriously destabilising?
The following podcast looks at these issues. “Aditya Chakrabortty’s joined in the studio by the Guardian’s economics editor Larry Elliott, as well as Roger Bootle, the managing director of Capital Economics, and political economist and John Maynard Keynes biographer Robert Skidelsky. Also in the podcast, we hear from Nobel prize-winning economist, Elinor Ostrom, Freakonomics author Steven Levitt, and UN advisor and developmental economist Daniel Gay.”

Questions
- Why did most economists fail to predict the credit crunch and subsequent recession? Was it a problem with the models that were used or the data that was put into these models, or both?
- What was the Washington consensus? To what extent did this consensus contribute to the current recession?
- What is meant by systemic risk? How does this influence the usefulness of ‘micro’ financial models?
- What particular market failures were responsible for the credit crunch?
- What is meant by ‘rational behaviour’? Is it reasonable to assume that people are rational?
- Is macroeconomics too theoretical or too mathematical (or both)? If you think it is, how can macroeconomics be reformed to improve its explanatory and predictive power?
- Does a ‘really good economist’ need to have a good grounding in a range of social sciences and in economic history?
This podcast is from the Library of Economics and Liberty’s EconTalk site. In it, Scott Sumner of Bentley University discusses with host Russ Roberts the role of monetary policy in the USA since 2007 and whether or not it was as expansionary as many people think.
In fact, Sumner argues that monetary policy was tight in late 2008 and that this precipitated the recession. He argues that the standard indicators of the tightness or ease of monetary policy, namely the rate of interest and the growth in the money supply, were misleading.
Sumner on Monetary Policy EconTalk podcast (9/11/09)
Questions
- Why is it important to look at the velocity of circulation of money when deciding the effect of interest rate changes or changes in the monetary base? Can the Fed’s failure to take velocity sufficiently into account be seen as a cause of the recession?
- Is there evidence of a liquidity trap operating in the USA in late 2008?
- How could the Fed have pursued a more expansionary policy, given that interest rates were eventually cut to virtually zero and the monetary base was expanded substantially?
- Why does Sumner argue that monetary policy should focus on influencing the growth in aggregate demand?
- How useful is the quantity equation, MV = PT (or MV = PY) in understanding the role and effectiveness of monetary policy?
- What is the Keynesian approach to monetary policy in a recession? How does this differ from the monetarist approach? Are both approaches focusing on the demand side and thus quite different from supply-side analysis of recession?
- Why is the consumer prices index (CPI) a poor indicator of a nominal shock to the economy? Should the central bank focus on nominal GDP, rather than CPI, as an indicator of the state of the economy and as a guide to the stance of monetary policy?
- What are the strengths and weaknesses of using a Taylor rule as a guide to monetary policy? Would nominal GDP futures be a better target for monetary policy?
The Bank of England’s latest quarterly Inflation Report was published on November 11. With all the gloomy news over the past few months the report is pleasantly up-beat – certainly for the longer term. As Mervyn King, Governor of the Bank of England, states in his opening remarks to the publication of the report, “The considerable stimulus from the past easing of monetary and fiscal policy and the depreciation of sterling should lead to a recovery in economic activity.”
Nevertheless, recovery will be slow, especially at first. This means that it will be some time before output returns to pre-recession levels. “Despite a recovery in economic growth, output is unlikely, at least for a considerable period, to return to a level consistent with a continuation of its pre-crisis trend. That is in large part because the impact of the downturn on the supply capacity of the economy is expected to persist. But it is also because there is likely to be sustained weakness of demand relative to that capacity.”
There is surprisingly good news too on employment and unemployment. Although unemployment has risen sharply in recent months, the rate of increase is slowing and “There was a small increase of 6000 in the number of people in employment to 28.93 million, the first quarterly increase since May–July 2008 (see Labour market statistics, November 2009).
So should we be putting out the flags? Can the Bank of England ease off on quantitative easing (see Easing up on quantitative easing)? Or does it still need to keep on increasing money supply, especially as fiscal policy will have to get a lot tighter? The following articles consider the issues.

Questions
- Explain what the three fan charts, Charts 1, 2 and 3 on pages 6, 7 and 8 of the Inflation Report, show.
- Why is the Bank of England more optimistic than in its previous report (August 2009)?
- Why did the sterling exchange rate fall on the publication of the report?
- Has the policy of expansionary monetary policy proved to be beneficial and should the Bank of England continue to pursue an expansionary monetary policy?
- What determines the balance of effects of an expansionary monetary policy on (a) asset prices; (b) real output; and (c) inflation?
- How have relatively flexible labour markets affected the impact of recession on (a) wage rates; (b) unemployment?
After the November 2009 meeting of the Monetary Policy Committee, the Bank of England announced that it would keep Bank Rate on hold at 0.5%, at which rate it has been since March. It also said that it would spend a further £25 billion over the next three months on asset purchases, primarily government bonds, thereby pumping additional money into the economy: the process known as “quantitative easing“. This would bring total asset purchases under the scheme to £200bn.
But although this represents a further increase in money supply, the rate of increase is slowing down. In the previous three months, £50 billion of assets had been purchased. So does this imply that the Bank of England sees a recovery around the corner? Will money supply have been expanded enough to finance the desired increase in spending – on both consumption and investment?
A problem so far is that most of the extra money has not been spent on goods and services. Banks have been building up their reserves, with much of the money simply being re-deposited in the Bank of England as reserve balances (see Table A1.1.1 in “Bankstats). At the same time, households have been taking on very little extra debt – indeed, In July, total household debt actually fell (see “Payback time) and consumer debt (i.e. excluding mortgages) has continued to fall. If quantitative easing is to work, the money must be spent!
But with the monetary base having expanded so much, is there a danger that, once the recovery gathers pace, spending growth will return with a vengeance? Will inflation rapidly become a problem again with an overheating economy? The following articles examine the issues.

Questions
- What has been happening to the velocity of circulation of (narrow) money in the past few months? Explain the significance of this.
- What is likely to happen to the velocity of circulation in the coming months if (a) the economy recovers quite strongly; (b) recovery is modest?
- What is the relationship between quantitative easing and the growth in broad money (i.e. M4 in the UK)? How will banks’ desire to build up their reserves affect this relationship?
- Is the UK economy in a liquidity trap? Explain.
- Why is it likely that the Bank of England may well engage in more quantitative easing next March and beyond? How is the fiscal situation likely to affect Bank of England decisions?
- Examine the argument for the Bank of England buying more private-sector debt (virtually all of the asset purchases have been of public-sector debt)?
A key determinant of the length of any phase of the business cycle is consumer confidence. If people have gloomy expectations and confidence of a recovery is low, then a recession that should have lasted 6 months ends up lasting for years. Companies don’t see an end to the recession and keep holding off on investment plans and the public don’t want to go out and start spending, because there’s no guarantee that the economy is on its way back up. The more you worry about your finances, the less likely you are to go out and start spending, even though that could be the stimulus that a shrinking economy needs.
According to the British Retail Consortium, consumer confidence in the UK is on its way back up and currently stands at an 18-month high – which doesn’t actually say much given the past 18-months!! Despite this, job worries still remain and this has been highlighted significantly in the past week, when Britain’s youngest person ever was made redundant: a 13-year old paper boy. Whilst consumer confidence is argued to be returning to the UK, consumer confidence has been going in the opposite direction in the USA, with further fears of job losses. US confidence had been improving but unexpectedly fell in October. Is that what the UK has to look forward to?
So, why is consumer confidence so important? How does it affect the length of recovery and what is expected to happen over the next few months? Read the articles below to find out more.

Questions
- In what ways does consumer confidence affect economic growth?
- Are there likely to be any adverse consequences of consumer confidence returning to the market?
- What are some of the reasons for the unexpected fall in consumer confidence in the USA? Do you think a similar thing is likely to happen in the UK?
- Expectations are crucial in economics. What is the difference between adaptive and rational expectations? How do they affect adjustment to the short- and long-run equilibrium?
- Can anything be done to improve confidence or is it simply a case of leaving things as they are … and waiting?
