Where did everyone go?

MILTON FRIEDMAN once compared the business cycle to an elastic string stretched on a board. How far the string is plucked determines how much it springs back; similarly, the depth of a recession decides the strength of recovery. America’s recent experience has not been kind to the plucking model. Although the recession was the deepest since the second world war, the recovery has been a disappointment. In the three years since the end of the recession in mid-2009, growth averaged 2.2%, barely half the 4.2% average of the seven previous recoveries.

In part, this is because recoveries from financial crises face greater difficulties. Consumers are too much in debt; businesses cannot or will not spend; a damaged banking system stifles credit. But in its annual economic report, issued on March 15th, Barack Obama’s Council of Economic Advisers argues that this is not the whole story. The plucking model presumes that after a recession, the economy returns to an underlying trend rate of growth that is determined by the supply of workers, capital and technology. Mr Obama’s economists argue that the trend is now much lower than in the past. The recovery, then, is not nearly as disappointing as it is often portrayed; Americans have set their sights too high.
