A Note on Third Degree Price Discrimination in Intermediate Good Markets
研究了中间品市场中三级价格歧视的定价问题，发现更高效的下游企业是否被收取更高价格取决于需求函数形状，例如在常弹性需求下高效企业会获得折扣。
This note studies third degree price discrimination in intermediate good markets. I show that whether a more efficient downstream firm is charged a higher or lower price than a less efficient firm depends on the shape of the demand function. Different from the case in which final market demand is linear, the usual assumption in the literature, constant elasticity demand, for example, results in a more efficient firm's receiving a discount.
