Pollutants, wastes and scrap appear as joint products of consumption or production processes. Leontief and other authors extend input-output (IO) tables such that additional products and industries, respectively, account for pollutants and abatement activities; they also analyze the effects of...

This paper is concerned with a comparison of the treatment of fixed capital in some multi-sectoral models. First, the dynamic Leontief model is investigated. Scrutiny shows that this model suffers from conceptual misconceptions which result from restrictive assumptions concerning full-capacity...

This paper is concerned with the treatment of fixed capital in multisectoral models. Five approaches and concepts developed and used by Sraffa and von Neumann, by Hicks, by Georgescu-Roegen, by Walras and by Leontief are compared. These five approaches fall into two broad categories: models with...

This paper aims at a clarification of the classical notion of the rate of profit with respect to the process of gravitation towards long period positions. It is demonstrated that some existing definitions of that rate, in particular 'synchronic' rates of profit which are based on a revaluation...

This paper compares alternative concepts of production and prices with a special emphasis on time. First, it is demonstrated that the point-input point-output representation of processes used in von Neumann-Sraffa models is not restrictive and can be derived from general flow-input flow-output...
