The thesis contains the theoretical basis for study of possibilities of pricing information goods. The source areas are microeconomics, marketing, competitive advantage and economics of information goods. The model of market is created with constraints defined on the ground of theoretical basis. The thesis analyzes requirements that define the system that supports the choice of pricing strategy. It includes detailed design of the prototype of such system. The prototype is designed with robustness because of the future improvements. The design describes the prototype's input parameters and their transformation into useful outputs that cover basic characteristics of information goods. The designed prototype is implemented. The thesis includes demonstration of the prototype and possible directions for improvements that lead to validity of proposed model of market.
