A linear-fractional exchange model. I: Existence and characterization of an equilibrium. (Russian) Zbl 1249.91079
Summary: We study an exchange model with linear-fractional utility functions for the participants. The existence of equilibria is studied. We find conditions for the existence of a strong equilibrium and of a “free disposal” equilibrium. For fixed budget exchange models, we obtain a reduction of the initial problem to the polyhedral complementarity problem.
