As in Roemer (1982, chapter 1), this paper considers a simple international trade model and examines the existence and characterization of free trade equilibria involving the unequal exchange of labor (UE). The paper provides an almost complete characterization of the domain of economies in...

This report explores the development of exploitation theory in mathematical Marxian economics by reviewing the main controversies surrounding the proper definition of exploitation since the contribution of Okishio (1963). The report first examines the debates on the Fundamental Marxian Theorem...

A dynamic general equilibrium model that generalises Roemer's [23] economy with a global capital market is analysed. An axiomatic analysis of the concept of unequal exchange (UE) between countries is developed at general dynamic equilibria. The class of UE definitions that satisfy three...

This paper critically analyses the strongly subjectivist approach to exploitation theory recently proposed by Matsuo ([7]), in the context of general convex economies with heterogeneous agents. It is proved that the Fundamental Marxian Theorem is not preserved in his subjectivist approach,...

In subsistence economies with general convex technology and rational optimising agents, a new, axiomatic approach is developed, which allows an explicit analysis of the core positive and normative intuitions behind the concept of exploitation. Three main new axioms, called Labour Exploitation in...
