A non-substitution theorem with heterogeneous labor

Abstract

My first goal in this paper is to prove Proposition 1 under assumption which are far more general tan the Leontief-type assumtion usually associated to the proof of the non-substitution theorem. A second goa lis to prove also Proposition 2 under les stringent assumptions tan the usual ones; in particular, my proof will make room for heterogeneous labor. The paper is organized as follows. In section I, I introduce a fairly general structure representing the productive parto f an economy. In section 2, I prove the theorems. Finally, in section 3, I discuss the import and limitations of the present versión of the non-substitution theorem here introduced, and the open problems left for further research.
