Corruption was, is and most likely in the future remains one of the forms of economic behavior with serious societal implications. Aim of this paper is to present one of the possible ways of analysis of the issue of corruption relevant instruments for research in economics. The present article is a microeconomic analysis of the causes and motives of corrupt conduct. In contrast to the opinions of psychologists and sociologists have come out from the assumption that you can not get by just listing the various causes of antisocial, and a decision on participation in illegal activities is accompanied by a systematic, rational economic calculation - calculation of risk (cost) of these activities and their expected benefits.

The nature and means of decision has been of interest to philosophers since ancient Greece. A new scientific discipline has taken shape: neuroeconomics - which attempts to unify the advancements and research results of psychology, neuroscience and economy into a unified scope. Neuroeconomics has its supporters and vigorous opponents particularly among economists, some of who consider neuroeconomics dubious or irrelevant. Recently the first molecular genetic studies have begun to appear. The social decision described by the theory of expected utility and by the prospect theory has in its simplified point of view two tiers: the first phase is valuation, the second is a choice from a number of possibilities. Key nodes of the "common neural currency" are -- the tegmentalis ventralis, -- pars compacta of the substantia nigra, -- nc. caudatus, -- the ventral striatum, -- orbitofrontal and medial prefrontal cortex. Key nodes responsible for choice are -- parietal and -- lateral prefrontal cortex. The evolutionary perspective says that human decision making is not guided by utility maximization but by operation of numerous decision rules shaped by selection to solve specific adaptive problems.
