Title:Bilateral Ratings and P2P Market Competition and Segmentation

Speaker:T. Tony Ke, MIT Sloan School of Management

Time:Wednesday, April 26, 13:30-15:00

Place:Room 217, Guanghua Building 2

Abstract

This paper examines how bilateral ratings influence market segmentation of heterogeneous consumers on a matching platform. Under a competitive search and matching framework, we show that in equilibrium, consumers with low cost-to-serve (i.e., good ratings) apply to both high-quality and low-quality service providers, and expect a higher utility; while consumers with high cost-to-serve (i.e., bad ratings) apply to only low-quality service providers, and expect a lower utility. We compare the equilibria under bilateral and unilateral ratings, and find that bilateral ratings may soften competition, lead to higher prices, and thus harm consumers’ welfare.
