Catherine Rampell, writing Ostrom's obituary for the New York Times:
Professor Ostrom’s work rebutted fundamental economic beliefs. But to say she was a dark horse for the 2009 economics Nobel is an understatement. Not because she was a woman — although women in the field are still rare — but because she was trained in political science.
Professor Ostrom’s prizewinning work examined how people collaborate and organize themselves to manage common resources like forests or fisheries, even when governments are not involved. The research overturned the conventional wisdom about the need for government regulation of public resources.
