What is pricing discrimination?

Price discrimination is the practice of charging the highest price to different consumers. This is so that the firm can maximize the revenue it receives for the goods it produces. Price discrimination is mainly for markets that are monopolistic, or oligopolistic. In these kinds of markets the firm has to decrease price in order to sell more of the good because they are the only supplier. Because of this marginal revenue is derived from the demand but the profit maximization condition is still marginal cost equals marginal benefits but marginal benefits does not equal the demand curve. The firm wants to price discriminate in order to avoid the decreased revenues because of the lost revenue because they have to decrease prices to get more consumers. One of the biggest problems in practicing price discrimination is that the firm needs perfect information in order to maximize the returns to price discrimination. Finding this information could be very costly to obtain, or could be realistically impossible to obtain.
