Study of mathematical models of economic processes by methods of the theory of covering mappings
In this paper, we study the Walras-Evans-Samuelson dynamic continuous model for a two-commodity market using the theory of covering mappings. We obtain sufficient conditions for the existence of an equilibrium position in this model. The equilibrium in this model is considered as a point of coincidence of two mappings: the demand mapping and the supply mapping, which depend on the prices for the presented types of goods and on the rates of change of these prices.
