Segmentation, Advertising And Prices
Source: Tinbergen Institute
This paper explores the implications of market segmentation on firm competitiveness. In contrast to earlier work, here market segmentation is minimal in the sense that it is based on consumer attributes which are completely unrelated to tastes. The authors show that when the market is comprised by two consumer segments and when there is sufficient variation in the per-consumer costs firms need to incur to access the different segment populations, then firms obtain positive profits in symmetric equilibrium. Otherwise, the equilibrium is characterized by zero profits. As a result, a minimal form of market segmentation combined with advertising cost asymmetries across consumer segments give firms an opportunity to generate positive rents in an otherwise Bertrand-like environment.
