Strategic Payoffs of Normal Distributionbump into Nash Equilibriumin 2 × 2 Game
نویسنده
چکیده
In this paper we assume that strategic payoffs are Normal distribution, and discuss how the parameters of Normal distributions affect the NE payoff distribution that is also concerned by players. We find that distortions of NE payoff distributions are dominated by the distance between variances of strategic payoffs in small means cases and the variances of the dominantly strategic payoffs in large means case. We also find that the variances of strategic payoffs lead to the higher means of the NE payoff distributions, which contain risk premium and the dominantly strategic payoffs, whatever the means of strategic payoffs. However, compared with the dominant strategy that is NE of static game, our model obtains that the mean magnitudes of strategic payoffs lead to establish the different rade-off relationship between means and variances of the NE payoff distribution in the decision-making process.

Leadership with Commitment to Mixed Strategies∗
A basic model of commitment is to convert a game in strategic form into a “leadership game” where one player commits to a strategy to which the other player chooses a best response, with payoffs as in the original game. This paper studies subgame perfect equilibria of such leadership games for the mixed extension of a finite game, where the leader commits to a mixed strategy. In a generic two-p...
متن کاملNash Equilibrium Strategy for Bi-matrix Games with L-R Fuzzy Payoffs
In this paper, bi-matrix games are investigated based on L-R fuzzy variables. Also, based on the fuzzy max order several models in non-symmetrical L-R fuzzy environment is constructed and the existence condition of Nash equilibrium strategies of the fuzzy bi-matrix games is proposed. At last, based on the Nash equilibrium of crisp parametric bi-matrix games, we obtain the Pareto and weak Pareto...
متن کاملEquitable Risk Allocation in Construction Projects: Fuzzy Bargaining Game Approach
An equitable risk allocation between contracting parties plays a vital role in enhancing the performance of the project. This research presents a new quantitative risk allocation approach by integrating fuzzy logic and bargaining game theory. Owing to the imprecise and uncertain nature of players’ payoffs at different risk allocation strategies, fuzzy logic is implemented to determine the value...
متن کاملDiscovering Theorems in Game Theory: Two-Person Games with Unique Pure Nash Equilibrium Payoffs
In this paper we provide a logical framework for using computers to discover theorems in two-person finite games in strategic form, and apply it to discover classes of games that have unique pure Nash equilibrium payoffs. We consider all possible classes of games that can be expressed by a conjunction of two binary clauses, and our program rediscovered Kats and Thisse’s class of weakly unilater...
متن کاملDelegation equilibrium payoffs in integer-splitting games
This work studies a new strategic game called delegation game. A delegation game is associated to a basic game with a finite number of players where each player has a finite integer weight and her strategy consists in dividing it into several integer parts and assigning each part to one subset of finitely many facilities. In the associated delegation game, a player divides her weight into sever...
