discriminating monopoly

In economics, discriminating monopoly refers to a situation where a single seller sells the same product to different buyers at different prices, even when the cost of selling is the same for all transactions. This practice is also known as price discrimination.12

For price discrimination to be successful, it must be impossible for other businesses to buy the product at a lower price and resell it at a higher one. Legislation often aims to prevent this practice when it's used by one seller to eliminate competition by undercutting prices in a competitor's market while charging higher prices elsewhere. The Robinson-Patman Act in the U.S., for example, prohibits price discrimination to protect smaller businesses from being driven out by larger companies. The effectiveness and impact of price discrimination on consumers are subjects of ongoing debate.13
