  2. Economic equilibrium - Wikipedia

    en.wikipedia.org/wiki/Economic_equilibrium

    An economic equilibrium is a situation when the economic agent cannot change the situation by adopting any strategy. The concept has been borrowed from the physical sciences. Take a system where physical forces are balanced for instance.This economically interpreted means no further change ensues.

  3. Arrow–Debreu model - Wikipedia

    en.wikipedia.org/wiki/Arrow–Debreu_model

    By definition of equilibrium, if is an equilibrium price vector for the restricted market, then at that point, the restricted market satisfies Walras's law. ~ is continuous since all ~, ~ are continuous.

  4. General equilibrium theory - Wikipedia

    en.wikipedia.org/wiki/General_equilibrium_theory

    In economics, general equilibrium theory attempts to explain the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that the interaction of demand and supply will result in an overall general equilibrium. General equilibrium theory contrasts with the theory of partial ...

  5. Long run and short run - Wikipedia

    en.wikipedia.org/wiki/Long_run_and_short_run

    Long run and short run. 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.

  8. Perfect competition - Wikipedia

    en.wikipedia.org/wiki/Perfect_competition

    In economics, specifically general equilibrium theory, a perfect market, also known as an atomistic market, is defined by several idealizing conditions, collectively called perfect competition, or atomistic competition. In theoretical models where conditions of perfect competition hold, it has been demonstrated that a market will reach an ...

  9. Economics - Wikipedia

    Market equilibrium occurs where quantity supplied equals quantity demanded, the intersection of the supply and demand curves in the figure above. At a price below equilibrium, there is a shortage of quantity supplied compared to quantity demanded. This is posited to bid the price up.
