The absence of perfect competition in the modern market economy indicates the differentiation of goods in the market in quality and price. Accordingly, it is necessary to use a differentiated approach to manufacturers in quality, and to buyers in income. As part of the differentiation of the zone of possible transactions, it is necessary to distinguish the zone of possible transactions and the equilibrium price for the rich part of the population and similarly for the poor, which, in turn, will establish the zone of possible transactions for the middle class. In order to simplify the study, three assumptions were introduced into the model: linear functions of supply and demand, abstraction from elasticity, abstraction from the quantity of goods. As part of a differentiated approach to establishing equilibrium prices, three options for the model were considered: gap, contact and overlap of the interests of the rich and poor.
As a result, a diverse differentiation of various types of goods was established relative to the three classes of the population by income. Thus, a significant gap between the zones of possible transactions (interests) is characteristic of household appliances, clothes, shoes, etc. The contact of interests is characteristic of the used car market, the overlap of interests is for agricultural products (tomatoes, cucumbers, potatoes, carrots, garlic).
Keywords:differentiation of buyers, differentiation of goods by quality, market equilibrium, equilibrium price, zone of possible transactions, rich, poor, middle class.
