The consequence of this is that in equilibrium, each firm's expectations of how other firms will act are shown to be correct; when all is revealed, no firm wants to change its output decision. [1] This idea of stability was later taken up and built upon as a description of Nash equilibria , of which Cournot equilibria are a subset.
The Nash equilibrium occurs when both firms are producing the outputs which maximize their own profit given the output of the other firm. In terms of the equilibrium properties, we can see that P2 is satisfied: in a Nash equilibrium, neither firm has an incentive to deviate from the Nash equilibrium given the output of the other firm.
The classical general equilibrium model aims to describe the economy by aggregating the behavior of individuals and firms. [1] Note that the classical general equilibrium model is unrelated to classical economics , and was instead developed within neoclassical economics beginning in the late 19th century.
An increased deficit by the national government shifts the IS curve to the right. This raises the equilibrium interest rate (from i 1 to i 2) and national income (from Y 1 to Y 2), as shown in the graph above. The equilibrium level of national income in the IS–LM diagram is referred to as aggregate demand.
Walras' arguments for the existence of general equilibrium often were based on the counting of equations and variables. Such arguments are inadequate for non-linear systems of equations and do not imply that equilibrium prices and quantities cannot be negative, a meaningless solution for his models. The replacement of certain equations by ...
Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...
If the curves do not cross, there is no equilibrium and no equilibrium output can be determined. The AD curve will have a positive, vertical intercept as long as there is some aggregated demand—from consumer spending, investment, net exports, or government spending—even if there is no national output. [5]
The Stackelberg model can be solved to find the subgame perfect Nash equilibrium or equilibria (SPNE), i.e. the strategy profile that serves best each player, given the strategies of the other player and that entails every player playing in a Nash equilibrium in every subgame.
