This study on the bases of multidisciplinary approach investigates the necessity of using the concept “institutional uncertainty” in economic and social researching, proves that the institutional uncertainty exists as a result of imperfect knowledge of economic agents rooting in economic agents' mentality. The institutional uncertainty is an obligatory attribute of institutional environment, because institutions have capability to generate not only “certainty”, but also “uncertainty”, and “risks” for economic agents. The institutional uncertainty as Knightian uncertainty reflect the unpredictability of changes of institutional environment and basic institutions (ethic, ethnic, cultural, ideology, political, business and so on), and the unpredictability of it influences on economic agents' behavior.
