Ray Fisman, the Lambert Family Professor of Social Enterprise, has started to write a monthly column in Slate.com. His columns report on recent economics research, sometimes his own, and discuss the significance of these research findings for social and economic issues. Recent posts covered “The bad economics of switching health-care plans”, “Will customers pay more to do good?” and “Why was war good for Angola’s big miners?” You can find a complete list of Professor Fisman’s Slate columns online.
