Mathematical needs and economic interpretations Durán, Miguel Ángel Economic methodology Existence General equilibrium theory Interpretation Mathematical economics This paper aims at showing that the disconnection between formal structures and theoretical content in economic model building could lead to undesirable consequences. In this sense, linking formal and verbal contents by means of coherent and relevant interpretations is worth the effort. For it is a relatively simple way of helping to improve the usefulness of mathematical economic theorization. By way of illustration of these ideas, the paper discusses the interpretation which Arrow and Debreu themselves put on the inclusion of free goods in their proof of existence of a general equilibrium. 2014-04-30T06:33:39Z 2014-04-30T06:33:39Z 2005 info:eu-repo/semantics/report Durán, M.A. Mathematical needs and economic interpretations.
