Introduction By and large, I will follow OR, Chapters 1l and 12, so I will keep these notes to a minimum. J Games with observed actions and payoff uncertainty Not all dynamic models of strategic interaction fit within the category of games with observed actions we have developed in the previous lectures. In particular, no allowance was made for payoff uncertainty

Introduction [Again, by and large, I will follow OR, Chap. 8, so I will keep these notes to a minimum. Review of key definitions Recall our three payoff aggregation criteria: discounting, i.e (u2)≥1>(2 (also recall that the payoff profile corresponding to a stream (ut)is taken to be(1 8)2t18t-u(a)); limit of means

Introduction The notion of subgame perfection is the cornerstone of the theory of extensive games. It embodies its key intuitions-and provides a vivid example of the difficulties inherent in such a theor But, above all, it has proved to be extremely profitable in a variety of applications. More- over, it has spawned a huge theoretical literature which has attempted(often successfully

对策论 对策是有厉害冲突的各方所分别采取的决策. 对策论,亦称为博弈论,研究具有对抗、竞争、冲突性质的 问题 最早利用数学方法来研究对策论的是数学家E. Zermelo,他于 1912年发表了论文《关于集合论在象棋对策中的应用》.1944 年, Von Neumann和O. Morgenstern总结了前人关于对策论 的研究成果,合著了《对策论与经济行为》(Theory of Games and Economic Behavior)一书,使得对策论的研究开 始系统化和公理化,并具有了深刻的经济背景.1994年,在对 策论研究中作出突出贡献的Nash, HarsanyiSe和获得诺贝尔经济学奖

毫无疑问贸易保护对世界福利是一种损害,但如何才能消除贸易壁垒实现自由贸易 呢?我们在前一章已经指出,寄希望于各国自觉采取单边贸易自由化是行不通的,必须各国 达成共识,一起采取行动,才能最终实现自由贸易。但是根据博弈论的观点,国家数目越多, 达成合作结果就越困难,反之当国家数目较少时,就比较容易达成合作

对策论 本章来介绍对策论(game theory) 对策是有厉害冲突的各方所分别采取的决策对策论,亦称为博弈论,研究具有对抗、竞争、冲突性质的问题 对策论的思想古已有之,如我国战国时期的“齐王与田忌赛马”最早利用数学方法来研究对策论的是数学家E. Zermelo,他于1912年发表了论文《关于集合论在象棋对策中的应用》.1944年

Therefore please send me email at your earliest convenience so I can add you to the list. You do not want to miss important announcements, do you?

Eco514 Game Theory Problem Set 4: Due Tuesday, November 9 1. Machines Extend Proposition 151.1 (the Perfect Folk Theorem with discounting) to arbitrary mixtures of payoff profiles of the original game G =(, (A Ui) ) Allow for both rational and real weights on the set of profiles {u(a): a E A}; note that the statement of the result will involve an approximation of the payoff profile

Eco514 Game Theory Problem Set 2: Due Thursday, October 14 Recall the following definitions: in any model M=(, (Ti, a: )eN), Ri is the event \Player i is rational\; R ien. Also, (E) is the event \Player i is certain that E is true\ and(E) NieN B (). This is as in Lecture 7
