         【摘要】We develop a theoretical model to study the complementarity between online and offline businesses. In a Salop circular city, a firm can choose to open only an online shop, to be located at the center of the city, or only physical shops, to be built along the circumference, or both online and physical shops. We illustrate two layers of complementarity between online and offline businesses. First, the online shop helps sell to consumers that are too costly to reach by offline shops. Secondly, when product quality is private information, which consumers cannot physically inspect and directly verify in the online shop, the offline shops generate an informed-consumer base which allows the online price to credibly reveal product quality. We further show that, when the variance of quality difference is large, social learning helps reduce the number of physical shops required for the online price to be informative. When the quality difference is small, for the online price to be informative, the firm not only needs a sufficiently strong social learning, but also needs the informed-consumer base to be sufficiently small.          【主講人介紹】                陳益卷，美國賓夕法尼亞大學經濟學博士，澳大利亞國立大學副教授。研究領域為產業組織理論，衛生經濟學。已經在Journal of Health Economics, Health Economics Journal of Mathematical Economics等國際知名期刊上發表多篇論文。          歡迎相關領域老師和同學關注并參加！如有意作為點評老師或宣講學生參加前沿文獻選讀活動，可以聯系經濟學院李三希老師 （sanxi@ruc.edu.cn）或者學生助理陳奕辰（chenyichen@ruc.edu.cn）。
