Value/originality. The article outlines the economic-mathematical model of “bribe maximization”, which takes into account the limitations of the possibility of offering and agreeing to receive a bribe. The model is the basis, which proves that the most effective way of fighting corruption is streamlining the efforts of the authorities on creating a competitive environment: “economic benefit – the risk of punishment”. These conditions decrease the officials’ interest to receive bribes since their size ceases to compensate for the risk of disclosure, detention, and punishment. Meanwhile, the series of other practices are also important, namely: building a holistic legal system based on integrity; introduction of mechanisms of accountability and responsibility of officials; cooperation with civil society and the private sector; adaptation of international experience to national realities; identification of “high risk zones” for diverting there main efforts and resources.
