A simple model from game theory, which can imitate a mechanism of corruption and cooperation patterns, is proposed. The settings are divided into two studies with examples related to safety of Moldovan economy. In Homo Economicus world, players seems to act in rational way and decisions are driven by payouts (metaphor for behavior in populations of selfish agents). In Homo Sociologicus world decisions are described by players acquiring reputation and evolving altruism, which in turn determine their choice of strategy (evolution of cooperation). I shall discuss both modeling approaches of Prisoner Dilemma, to understand collapse of cooperation and increase of corruption in post-communistic countries as Republic of Moldova. Possible more efficient for society outcomes (fairness equilibrium) are also discussed.
