The book focuses on reconstructing the theoretical contents and an immanent critique of the four central market sociological concepts of New Economic Sociology, associated with the names Granovetter, White, Fligstein, and Beckert. The thesis posits that these approaches cannot achieve their stated goal of explaining economic phenomena as social ones. To this end, their respective inconsistencies and gaps are elaborated upon. Finally, it is demonstrated that not only the explanatory structure of these approaches but also their explanatory gaps surprisingly resemble those of economics.
