Until the credit crunch and crash of 2008/9, there appeared to be a degree of consensus amongst economists about how economies worked. Agents were generally assumed to be rational and markets generally worked to balance demand and supply at both a micro and a macro level. Although economies were subject to fluctuations associated with the business cycle, these had become relatively mild given the role of central banks in targeting inflation and the general belief that we had seen the end of boom and bust.
True, markets were not perfect. There were problems of monopoly power and externalities. Also information was not perfect. But asymmetries of information were generally felt to be relatively unimportant in the information age with easy access to market data through the internet.
Then it all went wrong. With the exception of a few economists, people were caught unawares by the credit crunch. There was too little understanding of the complexities of securitisation and the leveraged risk in these pyramids of debt built on small foundations. And there was too little regard paid to the potentially destructive power of speculation and herd behaviour.
So how should economists model what has been happening over the past three years? Do we simply need to go back to Keynesian economics, which emphasised the importance of aggregate demand and the ability of economies to settle at a high unemployment equilibrium? Can the persistence of high unemployment in the USA and elsewhere be put down to a lack of demand or is the explanation to be found in hysteresis: the persistence of a problem after the initial cause has disappeared? Can failures of markets be incorporated into standard microeconomics?
Or do we need a new paradigm: one that emphasises the behaviour of economic agents and examines how people act when there are information asymmetries? These are the questions that are examined in the podcast below. It is an interview with Nobel Prize winning economist, Joseph Stiglitz.

In the UK, we have an inflation target of 2% and it’s the Bank of England’s job to use monetary policy, in particular interest rates, to keep inflation within 1 percentage point of its target. However, with rising commodity prices and the onset of recession back in 2008, interest rates had another objective: to prevent or at least lessen the recession. Bank Rate fell to 0.5% and there it has remained in a bid to encourage investment, discourage saving and increase consumption, as a means of stimulating the economy.
However, at such a low rate, interest rates are not acting as a brake on inflation, which is now well above target. This rise in inflation, has been largely brought about by cost-push factors, such as the restoration of the 17.5% VAT (up from the temporary 15%), higher oil and commodity prices, and a fall in the exchange rate. But part of the reason might be found in the increase in money supply that resulted from quantitative easing.
There are concerns that the UK may lose its credibility on inflation if action isn’t taken. The OECD has advised the Bank of England to raise Bank Rate to 3.5% by the end of 2011. The following articles consider this issue.

Questions
- Explain the relationship between interest rates and inflation. Why have such low interest rates caused inflation to increase?
- In 2008, the UK moved into recession, but was also suffering from inflation. This was unusual, as AD/AS analysis suggests that when aggregate demand falls, growth will fall, but so will prices. What can explain the low growth and inflation we saw in 2008?
- What is the difference between real and nominal GDP?
- What are the causes of the current high inflation and what solutions are available and viable?
- Why are expectations of inflation so important and how might they influence the Bank of England’s plans for interest rates?
- Do you think the OECD should have advised the Bank of England? Will there be any adverse effects internationally if the UK doesn’t heed the OECD’s advice?
- Is the OECD’s assessment of the UK in the above Country Summary consistent with its view on UK interest rates contained in pages 53 and 54 in the first OECD link?
The economic sentiment indicator for April 2010 published by the European Commission continues to show confidence in the UK economy rising. The UK experience mirrors that across the European Union. The increase in the level of confidence in the UK economy seen in April, as measured by responses to questions posed to businesses and consumers, was the fifth consecutive monthly rise in sentiment.
There is, however, something of a divergence between the moods of UK businesses and consumers. Consumer confidence fell very slightly in April, which follows on from a small fall in March. These falls might reflect some uncertainty amongst consumers induced by the UK general election and, in particular, the extent of future fiscal tightening. In contrast, general business confidence rose in April, especially in the construction and manufacturing sectors.
Nonetheless, confidence is considerably higher across both consumers and businesses than it was a year ago. The increase has been of such magnitude that the economic sentiment indicator has now been above its long-run average for two months in a row. We would perhaps be rather naïve to expect this trend to continue, not least because of the financial rebuilding that households, banks, business and, of course, government will be pursuing. Therefore, it will be fascinating to see how enduring the current levels of confidence are and whether the slight weakening in sentiment amongst UK consumers is a sign of things to come.

The consumer prices index (CPI) is used by the government and the Bank of England for measuring the rate of inflation, and in the 12 months to March 2010 it rose by 3.4%. This figure was above the expected rate of 3.1% and well above the Bank of England’s target of 2%. The other major measure of consumer prices, the retail prices index (RPI) rose by even more – by 4.4%.
In order to recover from the recession, the UK economy needs to grow, but as demand begins to rise, this could put further upward pressure on inflation. There are a number of influencing factors that have caused the recent rise in inflation (see Too much of a push from costs but no pull from demand). Large rises in housing, fuel, transport, many household services and food were contributing factors. Many of these factors, however, are thought to be temporary, so it may not be too much of a problem.
And anyway, at least if inflation does continue to rise, it won’t be unexpected!

A keenly awaited Budget, but what should we have expected? Chancellor Alistair Darling had warned that it wouldn’t be a ‘giveaway’ budget. The aim to cut the budget deficit in half over 4 years still remains and the UK economy is certainly not out of the woods yet.
You’ve probably seen the debate amongst politicians and economists over what should happen to government spending and it might be that the lower than expected net borrowing for 2009-2010 provides a much needed boost to the economy. With the election approaching, it seemed likely that some of this unexpected windfall would be spent. The following articles consider some key issues ahead of the 2010 Budget.

- Net borrowing for 2009/10 is expected to be lower than forecast. What should happen to this so-called ‘windfall’?
