The concept of sector

Christian Bidard () and Guido Erreygers ()

Working Papers from University of Antwerp, Faculty of Business and Economics

Abstract: We generalize the concept of industry, which stems from the analysis of single-product economies, to that of sector. The sector concept can be applied to economies with or without joint-product processes and pure capital goods. A ‘sectoral economy’ is an economy characterized by the ‘super-adjustment’ property: any strictly viable subset of methods can adapt itself to an arbitrary final demand. Given a few additional asumptions, the competitive prices are minimal in a sectoral economy, so that the subset of competitive methods is uniquely defined and the non-substitution property holds.
