The long-run equilibrium point for a perfectly competitive market occurs where the demand curve (price) intersects the marginal cost (MC) curve and the minimum point of the average cost (AC) curve. When demand is not the same as supply, we say that there is economic disequilibrium. Meaning of Equilibrium: The word ‘equilibrium’ is derived from the Latin word an equilibrium which … It produces a quantity depending upon its cost structure. In game theory, a subgame perfect equilibrium (or subgame perfect Nash equilibrium) is a refinement of a Nash equilibrium used in dynamic games.A strategy profile is a subgame perfect equilibrium if it represents a Nash equilibrium of every subgame of the original game. When demand increases, the demand curve shifts to the right from DD to D 1 D 1 (Fig. So this right over here would be the equilibrium, equilibrium quantity for the market, and this right over here would be the equilibrium price for the market.

This is a generalization of the fact that backward induction results in a Nash equi - librium, as established in Proposition 9.1. 105 likes. A subgame perfect equilibrium of a game G is a Nash Equilibrium of G that corresponds to a Nash Equilibrium in every subgame of G. Let's take a really simple example with two players, Russia and Ukraine. Chess), I the set of subgame perfect equilibria is exactly the set of strategy pro les that can be found by BI.
