個經問題，麻煩高手解答一下... - 經濟

期末考考古題。

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.

老實說前面有一題是用部分均衡分析的，

我認為畫圖比較完全競爭廠商與獨占廠商就可以了，

但是這題是用一般均衡分析法去做，我有點摸不著頭緒。





還有一題是

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.


證明庫諾均衡就是NASH解，不知道要從何證起...
