Quality-price models of opportunistic behavior of monopoly and monopsonist
Abstract
The article is devoted to the problem of opportunism in monopoly markets, which is so relevant for improving the welfare of the population and the effectiveness of regulating the interaction of market agents by the state and decision-making by the Federal Antimonopoly Service of the Russian Federation. The equilibrium of a monopolist is considered under the condition that the only variable non-price factor, quality, is present in the market. The functions of qualitative and quantitative marginal costs of a monopolist and a monopsonist are obtained. Models of opportunistic quality-price behavior of a monopolist and a monopsonist regarding the sale and purchase of goods, represented by models of quadratic quality prices (graphically, an inverted parabola and a parabola), the maximum and minimum values of which are determined by the corresponding opportunistic coefficients, are proposed.
In studies of opportunism, special attention was paid to the price behavior of the monopolist and monopsonist. An opportunistic increase in quality prices for a manufacturer-seller is a non-linear increase in price, at the same time it is a loss of income for buyers due to the purchase of a low-quality product at a high price.
An opportunistic reduction in quality price for the consumer buyer is a non-linear price reduction, at the same time it is a loss for sellers in profit due to the sale of high-quality goods at a low price.
