Abstract

The article considers the problem of analysis and selection of measures of state regulation of the activities of exporting companies. This problem is considered on the example of the grain industry, in particular, wheat. Grain markets, as a rule, have an oligopolistic nature. We consider two types of market participants: many exporting companies and the state, which exercises the function of the market regulator. The goal of the state is to regulate domestic prices for critically important types of products. We use an approach to modeling that takes into account the interaction of market participants and allows us to coordinate the interests of independent producers and the state. A feature of our approach is that each player chooses a strategy for its behavior in the market within the framework of a certain optimization problem, which are related to each other through common variables. A mathematical formulation of the problem under study is given and methods for its solution are proposed. The results of scenario modeling and analysis of the impact of export restriction parameters on domestic prices are presented using the example of the wheat market.
