标题[商管] [经济]-寡占市场
时间Tue Feb 23 17:32:14 2010
1. The Nash equilibrium in a Bertrand price setting game in which firms first
choose output capacities resembles the equilibrium is :
a. the competetive model
b. the Cournot model
c. the cartel model
d. the price leadership model
这题答案是(a)
解释是说同质寡占的Bertrand equilibrium为P1=P2=MC 故为完全竞争均衡
但题目怎看出来它是同质或异质的阿
另外异质寡占的Bertrand equilibrium 则跟Cournot equilibrium一样是什麽意思阿?
2. The kinked demand curve theory of oligopoly predicts that
a. price and quantity will be sensitive to small cost changes
b. price and quantity will be insensitive to small cost changes
c. price will be sensitive to small cost changes but quantity will not
d. quantity will be sensitive to small changes but price will not
答案是(b)
我自己翻成
价格(P)跟数量(Q)与成本之间的关系不敏感，所以只能对成本造成小量的变动
不过我觉得还是不太懂
想请问高手帮我解释一下 或者举例一下 感恩

1F：→ otakuX:第二题是成本微幅变动 价格和数量不易变动 02/23 18:57
2F：推 ingles:第一题Bertrand model基本假设本来就是设定同质寡占罗~ 02/23 20:30
3F：→ ingles:但如果题目的两个厂商都各面对不同的需求线,且出来的解即 02/23 20:44
4F：→ ingles:为异质寡占的Bertrand equilibrium..有误的话再请高手赐教 02/23 20:45
