Product Diversity in Asymmetric Oligopoly: Is the Quality of Consumer Goods too Low?
We analyze an oligopoly model with horizontal di¤erentiation and quality di¤erences. High quality goods are over-priced and under-produced. When the market is fairly covered, low quality products may be pro…table when their social contribution is negative, leading to too many products in equilibrium. In a relatively uncovered market, even low quality goods are under-produced and there may be too few entrants. However, when …xed costs di¤er across qualities, the market may produce low quality goods when it should produce high quality ones. The model is calibrated using market data for yoghurt.
