Linear-fractional exchange model. Part 1: Existence and characterization of equilibrium

In this paper we consider an exchange model with linear-fractional utility functions of consumers. Existence of equilibria are studied. We adduce existence conditions for the free disposal and strong equilibrium. For the fixed budget exchange model a reduction of the initial problem to the polyhedral complementarity one is obtained.

Keywords: linear-fractional function, exchange model, economic equilibrium, price vector, polyhedral complementarity.
