演講摘要 : There is more than one price policy in the spatial market, mainly because the shipment of a product is costly, and buyers are dispersed over space. The first attempt to examine the effect of alternative spatial price polices in the literature is made by Smithies (1941), whose well-known conclusion hereupon is that the firm's choice etween alternative price policies depends on the shape of consumer demand. However, it is worthy pointing out that there is one assumption imposed by Smithies (1941) and has customarily been adopted by subsequent studies, namely, the fixed market area assumption under which the market area is exogenously determined and same under alternative price policies. This paper attempt to provide a comprehensive and systematic exploration of the firm's choices and resultant economic benefits under alternative simply price policies in a spatial market in which among others, the market area is variable. We show that the firm serves the same market area under simple price policies if and only if demand is linear, and the market area must be smaller (larger) under mill price than uniform price when demand is convex (concave), that is, when demand is nonlinear, the space actually served by a firm canno et area assumption, some conclusions obtained by Beckmann
