This book argues that the lack of adequate theories of contemporary capitalism is due to the increasing separation of the sub-disciplines of Comparative and International Political Economy. Theorizing only takes place in one of the two over-specialized sub-disciplines of Political Economy, thereby leading to a neglect of the interplay between national and international dimensions of capitalism. The author seeks to rectify this gap by developing a theory of Second Image IPE. Based on the "second image" notion developed by Kenneth Waltz, he furthers the classical theoretical approaches as developed by Peter Gourevitch and Peter Katzenstein.
