From MIT Technology Review, "The Natural Experimenter: MIT economist Josh Angrist’s meticulous methods have influenced scholars for two decades. Now he’s zeroing in on what makes some schools better than others." by By Peter Dizikes:
Over two decades, [Josh] Angrist’s natural experiments have made him a prominent figure within economics. As of August, he was one of the 100 most-cited economists in the world, according to the Federal Reserve Bank of St. Louis, which keeps data on more than 33,000 authors. Among his best-known papers are studies on the relationship between length of schooling and income; the effect military service has on earnings; and the link between class size and student achievement.*** "He’s had tremendous influence," says Whitney Newey, PhD ’83, chair of MIT’s Department of Economics, who was one of Angrist’s graduate-school advisors.
Angrist’s citation ranking within economics probably understates that influence. Biostatisticians, who study cause and effect in medicine and biological research, regularly cite his methods, and political scientists and sociologists have adopted natural experiments as a basic research tool as well.
