Significantly, an old economics imperialism is identified of the "as if market" style most closely associated with Gary Becker, the public choice theory of Buchanan and Tullock and cliometrics. But this has given way to a more "revolutionary" form of economics imperialism associated with the information-theoretic economics of Akerlof and Stiglitz, and the new institutional economics of Coase, Wiliamson and North. Embracing one "new" field after another, economics imperialism reaches its most extreme version in the form of "freakonomics", the economic theory of everything on the basis of the most shallow principles.
By way of contrast and as a guiding critical thread, a thorough review is offered of the appropriate principles underpinning political economy and its relationship to social science, and how these have been and continue to be deployed. The case is made for political economy with an interdisciplinary character, able to bridge the gap between economics and other social sciences, and draw upon and interrogate the nature of contemporary capitalism.
