Explanation: In economics, a monopsony (mono: single) is a market form in which only one buyer faces many sellers. It is an example of imperfect competition, similar to a monopoly, in which only one seller faces many buyers. As the only purchaser of a good or service, the monopsonist may dictate terms to its suppliers in the same manner that a monopolist controls the market for its buyers. It is also known as Single buyer Right. A singlepayer universal health care system, in which the government is the only'buyer' of health care services, is an example of a monopsony. Another possible monopsony could develop in the exchange between the food industry and farmers.
