A theory of sequential reciprocity 总被引:13,自引:0,他引:13
Many experimental studies indicate that people are motivated by reciprocity. Rabin [Amer. Econ. Rev. 83 (1993) 1281] develops techniques for incorporating such concerns into game theory and economics. His theory is developed for normal form games, and he abstracts from information about the sequential structure of a strategic situation. We develop a theory of reciprocity for extensive games in which the sequential structure of a strategic situation is made explicit, and propose a new solution concept—sequential reciprocity equilibrium—for which we prove an equilibrium existence result. The model is applied in several examples, and it is shown that it captures very well the intuitive meaning of reciprocity as well as certain qualitative features of experimental evidence. 相似文献

I prove the subgame-perfect equivalent of the basic result for Nash equilibria in normal-form games of strategic complements: the set of subgame-perfect equilibria is a nonempty, complete lattice—in particular, subgame-perfect Nash equilibria exist. For this purpose I introduce a device that allows the study of the set of subgame-perfect equilibria as the set of fixed points of a correspondence. My results are limited because extensive-form games of strategic complementarities turn out—surprisingly—to be a very restrictive class of games. 相似文献

We characterize the set of communication equilibrium payoffs of any undiscounted repeated matrix-game with imperfect monitoring and complete information. For two-player games, a characterization is provided by Mertens, Sorin, and Zamir (Repeated games, Part A (1994) CORE DP 9420), mainly using Lehrer's (Math. Operations Res. (1992) 175) result for correlated equilibria. The main result of this paper is to extend this characterization to the n-player case. The proof of the characterization relies on an analogy with an auxiliary 2-player repeated game with incomplete information and imperfect monitoring. We use Kohlberg's (Int. J. Game Theory (1975) 7) result to construct explicitly a canonical communication device for each communication equilibrium payoff. 相似文献

景区门票价格偏高的一个博弈论解释 总被引:14,自引:1,他引:14
宋子千 《桂林旅游高等专科学校学报》2004,15(1):31-34
指出景区产品是差别垄断产品,通过引入博弈论的思想,论证差别垄断这一特性可能使得景区自动趋向完全垄断价格,造成社会福利损失。这一模型可以解释我国门票价格偏高以及部分景点还在酝酿提价的现象。 相似文献

Drama theory and its relation to game theory. Part 2: Formal model of the resolution process 总被引:2,自引:0,他引:2
Nigel Howard 《Group Decision and Negotiation》1994,3(2):207-235
In a drama, characters' preferences and options change under the pressure of pre-play negotiations. Thus they undergo change and development. A formal model of dramatic transformation is presented that shows how the core of a drama is transformed by the interaction among the characters into a strict, strong equilibrium to which they all aspire. The process is seen to be driven by actors' reactions to various paradoxes of rationality. 相似文献

Drama theory and its relation to game theory. Part 1: Dramatic resolution vs. Rational solution 总被引:1,自引:0,他引:1
Nigel Howard 《Group Decision and Negotiation》1994,3(2):187-206
Drama theory differs from game theory in that it does not regard actors' preferences and perceived opportunities as fixed, but as capable of being changed by the actors themselves under the pressure of pre-play negotiations. Thus characters in a drama undergo change and development. A manyperson, multiphase theory of dramatic transformation is presented, showing how thecore of a drama (in the sense of game theory) is transformed by the interaction between the characters into a strict, strong equilibrium to which they all aspire. The process of dramatic transformation is shown to be driven by actors' reactions to various paradoxes of rationality; it is proved that when all these paradoxes have been overcome, a full dramatic resolution has been reached, satisfying actors' emotional and moral demands, as well as the demands of rationality. 相似文献

This paper considers a public-good economy with congestion, where participants jointly produce a public good from input of a private good. This economic model gives rise to a transferable-utility game, the profit game, that depends on consumer preferences and a congestion parameter. The simplicity of the game allows the maximum level of congestion that guarantees the nonemptiness of the core of the economy to be determined. It is known that the sustainability of the Lindahl equilibrium in the core of the economy depends on the distribution of profits. In this paper two distributions of profits are compared: the Lindahl solution and the marginal-contribution solution. The latter is more often in the core than the Lindahl solution which in turn Lorenz-dominates the marginal-contribution solution. 相似文献
