In game theory, a non-cooperative game is a game in which there are no external rules or binding agreements that enforce the cooperation of the players. A non-cooperative game is typically used to model a competitive environment. This is stated in various accounts most prominent being John Nash's 1951 paper in the journal Annals of Mathematics. [1]
In economic terms, the strong -core is the set of pre-imputations where no coalition can improve its payoff by leaving the grand coalition, if it must pay a penalty of for leaving. ε {\displaystyle \varepsilon } may be negative, in which case it represents a bonus for leaving the grand coalition.
An ineffective, non-binding price floor, below equilibrium price. A price floor could be set below the free-market equilibrium price. In the first graph at right, the dashed green line represents a price floor set below the free-market price. In this case, the floor has no practical effect.
Deadweight loss can also be a measure of lost economic efficiency when the socially optimal quantity of a good or a service is not produced. Non-optimal production can be caused by monopoly pricing in the case of artificial scarcity, a positive or negative externality, a tax or subsidy, or a binding price ceiling or price floor such as a ...
An example of a non-credible threat is demonstrated by Shaorong Sun & Na Sun in their book Management Game Theory. The example game, the market entry game, describes a situation in which an existing firm, firm 2, has a strong hold on the market and a new firm, firm 1, is considering entering. If firm 1 doesn’t enter, the payoff is (4,10).
Pricing, quantity, and welfare effects of a binding price ceiling. There is a substantial body of research showing that under some circumstances price ceilings can, paradoxically, lead to higher prices. The leading explanation is that price ceilings serve to coordinate collusion among suppliers who would otherwise compete on price.
A non-negativity constraint on the slack variable is also added. [1]: 131 Slack variables are used in particular in linear programming. As with the other variables in the augmented constraints, the slack variable cannot take on negative values, as the simplex algorithm requires them to be positive or zero. [2]
The simplest example is the family household. Other examples include barter economies, gift economies and primitive communism. Even in a monetary economy, there are a significant number of nonmonetary transactions. Examples include household labor, care giving, civic activity, or friends working to help one another.
