Final answer:
The practice of charging different prices to different buyers for the same product is known as price discrimination. It is associated with product differentiation and appears more in monopolistic competition than in perfectly competitive markets.
Step-by-step explanation:
The term applied to the practice of charging different prices to different buyers for the same product is known as price discrimination. This strategy is often observed in markets where the same product or service is sold at varying prices to consumers, based on factors like location, buyer's willingness to pay, the time of purchase, and more. Product differentiation and monopolistic competition, where a variety of styles, flavors, and other characteristics distinguish products from one another, can lead to situations where price discrimination is more feasible for businesses.
For instance, a business might charge higher prices in a wealthy neighborhood than in a middle-income area due to the different perceived demand and willingness to pay. In monopolistic competition, firms have some degree of market power due to this product differentiation, which enables them to engage in price discrimination more easily compared to perfectly competitive markets where products are largely the same and competition on pricing is fiercer.
