In most simple microeconomic stories of supply and demand a static equilibrium is observed in a market; however, economic equilibrium can be also dynamic. Equilibrium may also be economy-wide or general, as opposed to the partial equilibrium of a single market. Equilibrium can change if there is a change in demand or supply conditions.
Recursive competitive equilibrium, an economic equilibrium concept associated with a dynamic program; Static equilibrium (economics), the intersection of supply and demand in any market; Sunspot equilibrium, an economic equilibrium in which non-fundamental factors affect prices or quantities
If the supply curve starts at S 2, and shifts leftward to S 1, the equilibrium price will increase and the equilibrium quantity will decrease as consumers move along the demand curve to the new higher price and associated lower quantity demanded. The quantity demanded at each price is the same as before the supply shift, reflecting the fact ...
In a perfect market (one that matches a simple microeconomic model), an excess of demand will prompt sellers to increase prices until demand at that price matches the available supply, establishing market equilibrium. [1] [2] In economic terminology, a shortage occurs when for some reason (such as government intervention, or decisions by ...
In economics, the long-run is a theoretical concept in which all markets are in equilibrium, and all prices and quantities have fully adjusted and are in equilibrium.The long-run contrasts with the short-run, in which there are some constraints and markets are not fully in equilibrium.
Besides market structure, many factors contribute to conduct and market performance. Market pressures are similarly evolving therefore when decision making based on market performance it is essential to assess all the circumstances affecting competition rather than rely solely on measures of market structure.
In an economic model, an exogenous variable is one whose measure is determined outside the model and is imposed on the model, and an exogenous change is a change in an exogenous variable. [1]: p. 8 [2]: p. 202 [3]: p. 8 In contrast, an endogenous variable is a variable whose measure is determined by the model. An endogenous change is a change ...
A supply is a good or service that producers are willing to provide. The law of supply determines the quantity of supply at a given price. [5]The law of supply and demand states that, for a given product, if the quantity demanded exceeds the quantity supplied, then the price increases, which decreases the demand (law of demand) and increases the supply (law of supply)—and vice versa—until ...
