When the price paid for a variable input is less than its marginal revenue product, it is known as monopsonistic exploitation. Monopsony power is the ability of a single buyer or group of buyers (such as a company) to exert significant control over the price of a particular good or service. This can result in the buyer paying a lower price for inputs than the inputs would fetch in a competitive market. As a result, the input suppliers are exploited and receive a lower price than they would in a truly competitive market.
