The Nobel in Economic Science Awarded to Commons Researcher Elinor Ostrom

From the New York Times, October 12, 2009
The Nobel in economic science was awarded to Elinor Ostrom, the first woman to receive the prize, and to Oliver E. Williamson on Monday.

They share the prize for their separate work on economic governance, organization, cooperation, relationships and nonmarket institutions.

Both professors teach at American public institutions: Ms. Ostrom at Indiana University, Bloomington, and Mr. Williamson at the University of California, Berkeley.

Ms. Ostrom’s work focuses on the commons, such as how pools of users manage natural resources as common property. The traditional view is that common ownership results in excessive exploitation of resources — the so-called tragedy of the commons that occurs when fishermen overfish a common pond, for example. The proposed solution is usually to make users bear the external costs of their utilization by privatizing the resource or imposing government regulations such as taxes or quotas.

Ms. Ostrom’s empirical research has shown that this explanation is “overly simplistic,” the prize committee says: There are many cases around the world in which common property is “surprisingly well-managed.” In these cases commons users “create and enforce rules that mitigate overexploitation” without having to resort to privatization and government regulation (which can both pose their own practical difficulties).

The grasslands in the interior of Asia — shared for centuries in traditional group-based governance — are one such example. They appeared to fare better under group-based systems than under either socialism or privatization.

Ms. Ostrom received her Ph.D. in political science at U.C.L.A., and said in a phone interview during the prize committee’s announcement that she considers herself a political economist. She said she hopes her work may guide policy on climate change.
