The book begins by introducing a rigorous view of the logical foundations and structure of scientific theories based upon the work of Alfred Tarski, Patrick Suppes, Karl Marx, and others. Using and combining their methods, the book then goes on to reconstruct important economic theories – including utility theory, game theory, Marxian economics, Sraffian economic theory, and econometrics – proving all the main theorems and discussing the key claims and the empirical applicability of each theory. Through these discussions, this book presents, in a systematic fashion, a general philosophy of economics grounded in the structural view. Offering rigorous formulations of important economic theories, will be invaluable to all readers interested in the logic, philosophy, and methodology of economics. It will also appeal particularly to those interested in economic theory.
