Institutions as a Constituent of the Social Wealth and a Factor of the Synthesis of its Constituents

The publication is aimed at studying the role of institutions in the development of modern macroeconomic systems and the growth of their wealth. The integral, integrated, logical approach plus the mathematical modelling method were used for carrying out the analysis. It has been found that the value of institutions is defined for society through cost reduction, as opposed to the value of other accrued benefits that exist in forms of valuable material things, knowledge, information, etc., and the worth of which, accordingly, is determined by the growth of the end result (increase in their volume). A classification of institutions by the criterion of their efficiency for the development of society has been proposed. The economic-mathematical model has been built and analyzed in the form of a regression equation that expresses the dependence of GDP according to the purchasing power parity (PPP) per person from the corruption perception index. It has been found that there is a stochastic link between the corruptness of public governance and the formation of the wealth of modern macroeconomic systems. The obtained results can be applied in the sphere of public governance in the formation of Ukraine’s social and economic policy. Prospects for further research are an in-depth examination of the relationship between the institutional infrastructure of society and the level of its wealth
