In this paper, we estimate the consumer benefits of competition in the retail industry. In our analysis, we incorporated the service quality of retail outlets as outputs. In Japan, in the process of the deregulation of entry restriction on large-scale retail stores, specialty supermarkets have increased their market share with a low price strategy. At the same time, despite their high prices, convenience stores have increased their market share through 1990s. We demonstrate changes in market share for each retail format are explained by the changes in each formats respective service quality.
