MONOPSONY: A market characterized by a single buyer of a product. Monopsony is the buying-side equivalent of a selling-side monopoly. Much as a monopoly is the only seller in a market, monopsony is the only buyer. While monopsony could be analyzed for any type of market it tends to be most relevant for factor markets in which a single firm is the only buyer of a factor.
