Parametrical regulation of market economy mechanisms

The development of economic processes, within the frameworks of legislatively (normatively) established "game rules" adjusting attitudes (mechanisms of interaction) between the agents (enterprises, resources suppliers, and consumers), is appreciably defined by values of such economic parameters, as various tax rates, government spending, credit rates, norm of reservation, exchange rate, etc. The specified parameters frequently vary depending on an economic conjuncture and ways of an estimation their effective values are often unknown. The approach how to define effective values of the specified economic parameters - laws of parametrical regulation in the form of extremals of the corresponding variational problems is offered in the report.
