This paper studies the discrete model of the dynamics of prices, described by the difference equation, is the formalization of customary law Walras, according to which the price is increased by excess demand and decreases at a surplus sentence. Using a suitable change of variables and parameters, the model of the dynamics of prices reduced to the equation Ricker arising in mathematical biology in studying the relationship between stock and replenishment of fish populations. Given the presence of a periodic volatility in the market prices, such as seasonal, in this paper we consider a model with a periodically varying parameter characterizing the seasonal changes in supply and demand. The studies were conducted by analytical and numerical methods using environment Delphi. Defined stationary points and their stability. Based on the results of numerical experiments obtained bifurcation diagrams for each season.
