期末考考古题。
suppose there's only one firm in an industry.
Show that monopoly market leads deadweight loss via general equilibrium
analysis. Care fully explain your reasoning.
老实说前面有一题是用部分均衡分析的，
我认为画图比较完全竞争厂商与独占厂商就可以了，
但是这题是用一般均衡分析法去做，我有点摸不着头绪。
还有一题是
Suppose that the market demand for a duopoly market is Q=a-bP, where a and b
are constant. Both firms have constant average (and marginal) costs, c.
Show that the equilibrium of Cournot competition is a Nash equilibrium.
证明库诺均衡就是NASH解，不知道要从何证起...
