OLIGOPOLY, CONCENTRATION: Oligopoly is a market structure that contains a small number of relatively large firms, meaning oligopoly markets tend to be concentrated. A small number of large firms account for a majority of total output. Concentration unto itself is not necessarily bad, but it often leads to inefficient behavior, such as collusion and nonprice competition. Concentration is measured in three ways--market share, concentration ratio, Herfindahl index.

MARKET CONTROL: 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 control depends on the number of competitors. If a market has relatively few buyers, but a bunch of sellers, then the buyers tend to have relatively more market control than sellers. The converse occurs if there are a bunch of buyers, but relatively few sellers. If the market is controlled on the supply side by one seller, we have a monopoly, and if it is controlled on the demand side by one buyer, we have a monopsony. Most markets are subject to some degree of control.

DEMAND AND SUPPLY DECREASE

A simultaneous decrease in the willingness and ability of buyers to purchase a good at the existing price, illustrated by a leftward shift of the demand curve, and a decrease in the willingness and ability of sellers to sell a good at the existing price, illustrated by a leftward shift of the supply curve. When combined, both shifts result in a decrease in equilibrium quantity and an indeterminant change in equilibrium price.
