The subject of the study is to assess the possibility and effectiveness of applying the theory of rational choice in the field of law. Within the framework of this work, the issues of topical problems of applying the theory of rational choice in the field of entrepreneurship in financial markets are raised, as well as the question of which model of rational choice is the most preferable for increasing the effectiveness of legal regulation of entrepreneurial activity in financial markets.General aspect of the research: the context of the development of interdisciplinary research at the intersection of economics and law, "economic analysis of law", behavioral economics, rational choice theory. Theoretical aspect of the study: substantiation of the possibility and expediency of applying the model of strict rationality in the framework of legal regulation of entrepreneurial activity in financial markets.   Within the framework of this work, a conclusion is made about the expediency of applying a model of strict rationality in assessing the behavior of entities engaged in entrepreneurial activity in financial markets. As a result of the application of this model of strict rationality, a new horizon of opportunities opens up for the law enforcement officer to create indicators for assessing the unfair behavior of business entities in financial markets through the introduction of tools of economic science. In particular, it opens up the possibility of using ex ante analysis, which classically includes mathematical analysis and, accordingly, the tools of cooperative game theory, in particular, the Nash equilibrium method. The identification of various behavioral anomalies in the analysis of the relations of financial market participants will allow us to create a method of preventive detection of potential risks associated with the actions of business participants in financial markets, which may be recognized in advance as unfair.
