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...

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...
