计划
- 首先，把近些年 last final 做好。
- 然后，复习近些年的midterm。
- 最后，根据做错的题目，阅读slides。
- 考试的时候，永远从最简单的题目，做起。不会的，难得，就留到后面。交卷前，一定检查。
midterm 1
Types of games
- prisoner’s dilemma,
- a battle of the sexes,
- a pure coordination game
- 2017 midterm1 q6
- 合作，就获利，不合作，吃亏
- a zero sum game
- 2017 Midterm1 q1 A zero sum game (when the sum of all players payoff s for any strategy pro le is always equal to zero) has Nash equilibrium.
Static Game
- weakly dominated
- strictly dominated,
- 2017 midterm1 q8
- Solve the game by iterated elimination of strictly dominated strategies,
- Equilibrium not payoff, is strategies.
Credible threat
- Final – 2011 q1 In a sequential game, it can be useful for a player to have the ability to credibly commit to an action that would result in a disastrous outcome for all players
5.Nash Equilibrium in Pure Strategies for Continuous Strategy Spaces - Cournot/lecnotes5
5.1 - 2017 midterm1 q9
- 这一题，双方有不一样的成本，所以，best response 不一样。
- each payoff function.
- Best response function
- the Nash Equilibrium quantities
- quantity should produce
6.mixed strategy/lecnotes6
- 2017 midterm1 q4 In a mixed strategy equilibrium all pure strategies that are played with a strictly positive probability provide the same expected payoff against the other players’ strategies.
6.1 The Blue Chicken /2011 final q4
- pure strategy
- mixed strategy
- 如果有一方A的payoff 结构变了。那不是他A的probability p要变。而是对方B要变q，从而让他A在两个action之间indifferent。
- 警察抓醉驾司机的例子，也是一样。
9.Coase Theorem and Property Rights/lecnotes9
9.1 2017 midterm1 q8
- the payoffs under an assignment of property rights
- describe the range of Coasean contracts that could be written between the two farmers
