In this paper, we examine what appropriate formulations for labor exploitation are, in order to explain the emergence of class and exploitation status in capitalist economies. Given the well-known controversy on plausible formulations for labor exploitation in joint production economies, we...

In this paper, we reexamine the mathematical analysis of Marxian exploitation theory. First, we reexamine the validity of the two types of Marxian labor exploitation, Morishima's (1974) type and Roemer's type (1982), in the argument of Fundamental Marxian Theorem (FMT). We show that the FMT does...

In this paper, we correct a flaw in Proposition 1 of Yoshihara (2010). The original proof of Proposition 1 is correct only with the existence of reproducible solutions with zero profit rate. In contrast, this note provides an alternative characterization of the domain of economies under which...

This paper provides a mathematical analysis of the Marxian theory of the exploitation of labour in general equilibrium models. The two main definitions of Marxian exploitation in the literature, proposed by Morishima (1974) and Roemer (1982), respectively, are analysed in the context of general...
