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.

According to GDP figures released on 15 August, China overtook Japan in the second quarter of 2010 to become the world’s second largest economy. This raises two questions: just what do the GDP figures mean and why has this happened?
The GDP figures are total figures measured in US dollars at current exchange rates. According to these nominal figures, Japan’s GDP was $1.286 trillion in the second quarter of 2010; China’s was $1.335 trillion. This follows several years when Chinese growth rates have massively exceeded Japanese ones.
As far as explanations are concerned, economists look to a number of different factors, including investment policies, relative exchange rates, confidence, deflation in Japan and the scope for catching up in China.
The following podcasts and webcasts look at these questions, as do the articles.

Questions
- Why may simple GDP figures be a poor indicator of the relative size of the Chinese and Japanese economies?
- If purchasing-power parity figures were used, how would this affect the relative sizes of the two economies? Explain why purchasing-power parity exchange rates are so different from nominal exchange rates in the two countries.
- What impact have the relative exchange rates of the two countries had on economic growth?
- Why are simple GDP figures a poor indicator of living standards?
- What factors will determine whether income inequality is likely to widen or narrow in China over the coming years?
- What factors explain Japan’s low rate of economic growth since the early 1990s? How likely is it that these factors will apply in China in the future?
The link below is to a podcast by Martin Wolf of the Financial Times. It considers a new book, Fault Lines by Raghu Rajan of the University of Chicago Booth School of Business. Rajan argues that the global economy is severely unbalanced:
There is a fair amount of consensus that the world economy is in need of rebalancing. Countries like Iceland, Greece, Spain, and the United States overspent prior to the crisis, financing the spending with government or private borrowing, while countries like Germany, Japan, and China supplied those countries goods even while financing their spending habits. Simply put, the consensus now requires U.S. households to save more and Chinese households to spend more in order to achieve the necessary rebalancing.
Martin Wolf identifies these imbalances and discusses various possible solutions. The problem is that what may seem sensible economically is not always feasible politically.

Questions
- What are the fault lines that Martin Wolf identifies?
- Have they become more acute since the credit crunch and subsequent recession?
- What risks do these fault lines pose to the future health of the global economy?
- How do political relationships make integrating the world economy more difficult? What insights does game theory provide for understanding the tensions in these relationships?
- Is a policy of export-led growth a wise one for the UK to pursue?
- Explain why global demand may be structurally deficient.
Throughout 2009/10, a new millionaire was created in Brazil every 10 minutes – not bad for a developing country! Despite the global recession, Brazil has managed growth of almost 5% and is set to overtake both the UK and France to become the world’s 5th largest economy. Brazil will hold the next World Cup and the Olympic games after London, bringing it further recognition as a global power. It has the third largest aircraft manufacturing industry in the world and is even doing its bit to tackle climate change, with 50% of its cars running on bio-fuels. It exports more meat than any other country and is looking to become an energy power. With falling unemployment, a buoyant economy, growing confidence, fantastic beaches and 6 millionaires created every hour, Brazil looks like the perfect place to live.
However, that is just one side of the story. Brazil is still a country with deep poverty – approximately 60 million people. The slums, or favelas, are home to 1 million people in Rio alone, where unemployment is high and drug wars common. There has been a concerted effort to reduce the drug trafficking business, but this has only created more unemployment. There is little sanitation, poor electricity and minimal chance of escape. Neighbourhoods need rebuilding, and despite high growth and arguably the most popular president in the world (Lula da Silva), there are calls for political, social, taxation and labour market reforms. This cycle of poverty and the equality gap needs addressing before the Brazilian economy can really be considered a global power.

With the Conservatives and Liberal Democrats now in power in the UK and with the Labour Party, having lost the election, being now in the midst of a leadership campaign, politicians from across the political spectrum are balming Gordon Brown for the ‘mess the country’s in’. The UK has a record budget deficit and debt, and is just emerging from a deep recession, when only a few years ago, Gordon Brown was claiming the end of boom and bust. But is the condition of the UK economy Mr Brown’s fault? Would it have been any better if others had been in charge, or if there had been even greater independence for the Bank of England of if there had been an Office of Budget Responsibility (see)?
The following podcast by Martin Wolf, chief economics commentator of the Financial Times, considers this question. He argues that:
Everybody would like to blame Gordon Brown for the financial crisis. But he was only acting in line with the national consensus on economic policy.

Questions
- Explain what is meant by ‘the great moderation’.
- Should regulation of the banks be handed back to the Bank of England?
- Why may controlling inflation not necessarily result in stable economic growth? Is this a case of Goodhart’s Law?
- Why was the UK economy especially fragile during the banking crisis and its aftermath?
- What, according to Martin Wolf, was Mr Brown’s biggest mistake?
- Could a mistake be now being made by following the conventional wisdom that cutting the deficit is the solution to achieving sustained recovery?
