那么，什么是博弈论? 博弈论研究策略形式
So what is Game Theory? Game Theory is a method of studying strategic situation.
那什么是策略形式呢？
So what’s a strategic situation?
我们先看看什么不属于策略形式。
Well let’s start off with what’s not a strategic situation.，
在你们经济学基础课115或110中，应该讲过一些不是策略形式的案例
In your Economics, in your Intro Economics class in 115 or 110, you sow some pretty good examples of situation that were not strategic.
比如说自由竞争企业，这些企业是价格接受者
You saw firms working in perfect competition, Firms in perfect competition are price takers.
策略书面形式：行为影响结果，然而结果不仅取决你的行为，还取决于其他人的行为。
严格优势策略：如果选a得到的结果严格优于b，那么a对于b是个严格优势策略
协和漻误：按对方选择选择一样的
1，不要选择严格劣势策略
2，理性选择造成次优选择（囚徒困境，企业价格战）
3，站在别人的立场上分析别人会怎么做（换位思考） 协和廖误——优势策略得出
4，无法得到你想要的
5，收益很重要
r dilemma
Conclusions:1. Do not play a strictly dominanted straegy.
2. Rational choices can lead to bad outcomes.
3. Put yourself in other people`s shoes.
4. You can not get what you want unless you know what you want.
英文的还是有点难看懂
博弈必备因素：动机，收益
理性的选择，使总结果变得糟糕。
