This is a guest post by Bruce Wydick.
It isn’t hard to understand why Andrew Leigh would write a book on randomized controlled trials. A kind of modern renaissance man, Leigh currently serves as a member of the Australian House of Representatives. But in his prior life as an economist (Ph.D. from Harvard’s Kennedy School), Leigh published widely in the fields of public finance, labor, health, and political economy, even winning the Economic Society of Australia's Young Economist Award--a kind of John Bates Clark medal for Australians. His evolution from economist to politician must constantly evoke the following question: What is the best research approach for informing practical policy? In his new book, Leigh leaves little doubt about his answer. Randomistas: How Radical Researchers Changed Our World (forthcoming, Yale University Press) heralds the widespread incorporation of the randomized controlled trial (RCT) into the mainstream of social science.
