MILL AND UNIFORM PRICING A COMPARISON*
研究了非线性需求、一般消费者分布和运输成本下，工厂定价与统一定价对利润、价格、产量和福利的影响，发现需求凸性决定两种定价方式的优劣。
ABSTRACT. In this paper we examine profit, price, output and welfare under mill and uniform pricing in a monopolistic spatial market with nonlinear demand, a general consumer distribution function, and a general transportation cost function. We show that if demand is convex (concave) then the optimal uniform price minus the average unit transportation cost is lower (higher) than the optimal mill price, output under uniform pricing is lower (higher) than output under mill pricing, and welfare under uniform pricing is lower (higher) than welfare under mill pricing, provided other respective conditions are satisfied.
