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.

To mark the 20th anniversary of the fall of the Berlin wall, the BBC World Service commissioned a survey across 27 countries to gather people’s views about capitalism and whether it is working well. The findings are striking. Only 11% felt that it is working well. “Most thought regulation and reform of the capitalist system were necessary. There were also sharp divisions around the world on whether the end of the Soviet Union was a good thing.”
The following articles look at the detailed findings of the poll and consider its implications for the functioning and reform of the world economy.

The following article by Will Hutton looks at the relative efficiency of private- and public-sector organisations. The public sector is typically characterised as inefficient and providing a poorer level of service and poorer quality products than the private sector. After all, the private sector is driven by the profit motive, where providing a good service would seem to be a key ingredient in making more profit.
Yet when you look around you, this portrayal can be seen as far too simplistic. On the one hand, much of the public sector has been forced to be efficient, following many years of tight budgets. At the same time, many in the public sector are keen to deliver a good service, not only because that is required by their employers, but because they are motivated by a sense of public duty and professionalism. On the other hand, there are many market failings in large parts of the private sector, where monopoly power, asymmetric information and externalities are rife. Read the article and see if you agree with Will Hutton’s analysis.

Questions

- What market failures may prevent private-sector companies from achieving (a) to (c) above?
- What organisational failures may prevent public-sector organisations from achieving (a) to (c) above?
