THE BORDERS PROBLEM OF THEORY OF INSTITUTIONALISM
Institutionalism has had an enormous influence on the development of economic theory. This theoretical school broke the monopoly of "economism", established by the classical theory and marginalism. Institutionalists introduced into scientific circulation influence of non-economic factors on economic processes. Institutions and the institutions themselves were unconventional factors impact on the economy and their legal registration. Thanks to institutionalists economic theory enriched research activities of collective subjects in the economy, such as a state, enterprise unions, a family, community organizations, etc. Without the contribution of institutionalism economic theory would be one-sided and biased. However, neither the old institutionalists (T. Veblen, W. Mitchell, J. Commons), no new institutionalists nor neoinstitutsionalists did not introduced in their analysis such the most important elements affecting the economy as ethnic and religious characteristics of the different nations. Therefore, the problem of incompleteness of institutional theory is very relevant. At the moment, there are very few studies on this topic. The article discusses the need for integration in the institutional theory perspective of the historical school, which deals with the missing elements of the study: the influence of ethnic and religious factors on the economy.
