PRINCETON – The Initiative on Global Markets, based at the University of Chicago, periodically surveys a group of leading academic economists, of varying political persuasions, on the issues of the day. Its latest roundup asked whether President Barack Obama’s stimulus plan helped to reduce unemployment in the United States.
Officially known as the American Recovery and Reinvestment Act of 2009, the plan entailed government spending of more than $800 billion on infrastructure, education, health, and energy, tax incentives, and various social programs. Implemented in the midst of an economic crisis, it was the classic Keynesian response.
The economists were virtually unanimous. Thirty-six of the 37 top economists who responded to the survey said that the plan had been successful in its avowed objective of reducing unemployment. The University of Michigan economist Justin Wolfers cheered the consensus in his New York Times blog. The virulent public debate about whether fiscal stimulus works, he complained, has become totally disconnected from what experts know and agree on.
In fact, economists agree on many things, a number of which are politically controversial. The Harvard economist Greg Mankiw listed some of them in 2009. The following propositions garnered support from at least 90% of economists: import tariffs and quotas reduce general economic welfare; rent controls reduce the supply of housing; floating exchange rates provide an effective international monetary system; the US should not restrict employers from outsourcing work to foreign countries; and fiscal policy stimulates the economy when there is less than full employment.
