Makhort A. Modelling and calculating the influence of internal and external factors on price formation in an economy

The thesis concerns a study of the equilibrium problem in economic systems. The open economic system and the closed economic system with monopolies are investigated by using the model of an economy with regular interests of consumers formulated as the effective exchange model or the production model. Algorithms of searching economic acceptable solutions of the economic equilibrium problem are developed. Such solutions allow economic systems to function effective. The conditions on the defined characteristics of economic systems provided realising the proposed algorithms are found. The obtained theoretical results are used to an investigation of the Ukrainian economy. The analysis of the monopolies influence on efficiency functioning of the Ukrainian economy are considered.
