Abstract

This article mainly consists in a criticism towards the structuralistic reconstructions of exchange economies by Balzer and Stegmüller. It will be shown that Balzer's special law of market clearing is no specialization, that is, no additional axiom bu that it can rather be derived within his reconstruction, if we make one additional assumption, essential concerning exchange economies, and which is usually made in the economic literature. Moreover it will be argued from an economic point of view against separating a law of market clearing from maximizing utilities and regarding market clearing as a special law. Finally we will propose an alternative view.
