  abstract  = {This paper investigates the formation of the ownership structure and the corporate governance system of the Ukraine as a country in transition. Numerous studies consider that privatization results in the establishment of a proprietors' motivation mechanism. On the other hand it causes ownership concentration in the hands of a few shareholders and managers. The goal of economic reform in transition and, largely, its pace, is measured by the degree to which shareholders participate in short- and long-term corporate value creation. Shareholder access to such created value depends on the ability of corporate "insiders", especially executives and management, to claim a disproportionate share of corporate value (the "insider effect"). An econometric analysis of the correlation between privatization and macroeconomic factors studies the degree of effectiveness of economic reforming in Ukrainian regions.},
