Research Abstract

My research is focused on the competition with horizontally differentiated product in a duopoly market. In this kind of market, I analyze how the existence of consumer's switching costs influences the firm's strategy of behavior-based price discrimination in a two-period model. I have some theoretical results with game-theory approach, and they have many empirical implications on this kind of market such as a mobile telecommunication market.
