In Economics Imperialism and Interdisciplinarity: The Watershed and After, visionary economist Ben Fine selects and adds to his key articles tracking economics imperialism through three phases, with a special focus on the last decade of the third phase—anything goes as with freakonomics. Each article is accompanied by a preamble that sets the context in which it appeared, providing an overall introduction that draws out the lasting significance for contemporary scholarship. This volume ranges over mainstream and heterodox economics, the disputes between them, the relationship between economics and other disciplines, and discusses authors such as Edward Lazear, Joseph Stiglitz and George Akerlof. Through careful analysis the accelerating presence of economics imperialism is documented alongside its perverse, critical neglect. Economics Imperialism and Interdisciplinarity is imperative for those engaging in political economy across the social sciences.
