MARKET POWER: The ability of buyers or sellers to exert influence over the price or quantity of a good, service, or commodity exchanged in a market. Market power largely depends on the number of competitors on each side of the market. If a market has relatively few buyers, but many sellers, then limited competition on the demand-side of the market means buyers tend to have relatively more market power than sellers. The converse occurs if there are many buyers, but relatively few sellers. This is also termed market control.
