In the standard Okishio-Morishima approach, the existence of profits is proved to be equivalent to the exploitation of labour. Yet, it can also be proved that the existence of profits is equivalent to the ‘exploitation’ of any good. Labour and commodity exploitation are just different...

We examine the substantive arguments proposed by Kliman and Freeman (2006) in their reply to Mohun (2003). We find the temporal single-system interpretation (TSSI) seriously deficient.

La utilización de las matemáticas como herramienta para comprender la evolución de un sistema económico como el capitalismo ha reducido las categorías económicas del marxismo a la simplicidad. El desconocimiento de las magnitudes del valor en la determinación de la tasa de ganancia...

This paper shows that the ‘New Approach’ to the ‘problem of transforming values into prices’, first, is subjected to a crucial logical inconsistency and second, is not in a position to deal with the heterogeneous labour case. Thus, the paper proposes an approach, which overcomes these...

This paper is built around a theorem proved analytically and exemplified empirically in Flaschel, Franke and Veneziani (2010) which states that profitable capital-using labor-saving technical change is under mild conditions always reducing the labor content of commodities. This type of technical...

This paper presents a modern response to the problem imposed by Marx in Capital in 1867, “to lay bare the economic law of motion of modern society” and to provide a vision on how on the basis of this law of motion the transformation of the capitalist mode of production to the socialist mode...

This paper provides an empirical analysis of Marx's theory of exploitation built on the standard interpretation of the value of labour power. The relationship between the aggregate value rate of profit and the aggregate price rate of profit is studied and it is shown that the two rates coincide...

Economic objects are objects which are produced by employing inputs and valued by applying a valuation procedure. In a market economy the valuation is performed by the price mechanism. Ideally market prices reflect the scarcity values corresponding to individual preferences. This article argues...

The paper identifies as the root of the recent controversy in the theory of capital David Ricardo's finding that competitive prices and costs of production depend not only on the methods of production employed, but also on the wage rate (or rate of profits) and change with it. A consequence of...

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...
