中级微观经济学——有关于价格歧视.
1、Location competition of three vendors ina linear city.
2、Marginal cost is constant at c.Elasticity for demand are e1and e2.
3、lMarginal cost is constant at 20.Demandfunctions are D1(p1)=100 – p1,D2(p2)=120 – 2p2.

1. This problem is to find the Nash equilibrium for the three vendors. By symmetry of the problem, at least one of the vendors must be at the midpoint of the city. Suppose the other two vendors are distance x away from either end of the city, respectively, then the Nash equilibrium requires that x is less than the amount of customers the vendor at the center can get, which is equal to half of the distance between the other two vendors. Therefore,
x
再问： TR = Q1*p1 = Q1^(1+1/e1)/A^(1/e1) 这从哪来的吖，怎么都乘不出来吖！~
再答： p1 = (Q1/A1)^(1/e1) = Q1^(1/e1)/A^(1/e1) Q1*p1 = Q1*Q1^(1/e1)/A^(1/e1) = Q1^(1+1/e1)/A^(1/e1)
