Corruption occurs in relations between people and companies—agents who, in order to benefit from it, should make strategic decisions. This condition makes it possible to use game-theoretic apparatus to analyze it and there are many scientific works on the topic yet they mostly address the corruption in form of game between two or maximum three players. This research differs in its approach: it broadens the scope and analyzes corrupt agents acting not isolated but as parts of a bigger hierarchical structure in hope to obtain insights that may help to combat corruption in organizations. A subhierarchical two-stage game-theoretic model of embezzlement and bribery is created, the particular example with six officials on three levels is solved via computer simulation, settings for corruption minimizing and mild corruption minimizing are suggested and the cooperative extension is suggested.
