In economics, economic equilibrium is a state where economic forces such as supply and demand are balanced and in the absence of external influences the (equilibrium) values of economic variables will not change. For example, in the standard text-book model of perfect competition, equilibrium occurs at the point at which quantity demanded and quantity supplied are equal. Market equilibrium in this case refers to a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers. This price is often called the competitive price or market clearing price and will tend not to change unless demand or supply changes and the quantity is called "competitive quantity" or market clearing quantity. ==Properties of equilibrium== Three basic properties of equilibrium in general have been proposed by Huw Dixon.〔 (reprinted in Surfing Economics).〕 These are: Equilibrium property P1: The behavior of agents is consistent. Equilibrium property P2: No agent has an incentive to change its behavior. Equilibrium Property P3: Equilibrium is the outcome of some dynamic process (stability). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Economic equilibrium」の詳細全文を読む スポンサード リンク
