题目: Optimal Pricing Model of Digital Music: Subscription, Ownership or Mixed?（数字音乐最优定价模式研究：订购、下载购买以及混合模式）
主讲人: 李胜利 副教授，北京大学信息管理系
Traditionally, consumers purchase physical music (often in the form of CDs or cassettes) from local retailers. With the development of Internet technology, the market share of digital music has grown rapidly in recent years. Unlike physical music, digital music is provided by several emerging digital music providers through the Internet to consumers. Pricing models of digital music are also drastically different from those of physical music. In this paper, we identify three common schemes for selling digital music: ownership, subscription and mixed pricing models. Under the ownership model, consumers purchase and download their preferred songs and enjoy music using their local devices. Under the subscription model, music is provided through an online streaming service. The mixed pricing model is a combination of the previous two. Our paper explores and compares the three pricing models. Through a stylized model, we find that several factors, including the advertisement revenue rate and consumers’ reservation value for the music service, have crucial effects on the comparison of the three pricing models.

题目: Can Social Notifications Help to Mitigate Payment Delinquency in Online Micro-lending? A Field Experiment
主讲人: 卢向华 教授，复旦大学管理学院信息管理与信息系统系
Online micro-lending has experienced rapid growth worldwide. A key challenge in scaling up the business is managing the cost of debt collection incurred by late repayment and default. We study whether and how a platform can leverage on borrowers’ social connections through automatic social notifications in regulating repayment behavior. In collaboration with a large online micro-lending platform, we conduct a randomized field experiment to investigate the effect of social notifications targeted at different contact groups (core-circle vs. peripheral-circle). Our results show that notifying social contacts of a delinquent regarding the overdue payment significantly improves the repayment rate. Compared to the control group in which no notification messages are sent to the social contacts, notification-triggered social sanctions and social supports reduce the default rate by more than 50% in both core-circle and peripheral-circle groups. Further, we find that social notifications targeted at the peripheral-circle social contacts are only effective in the short term, its effectiveness decreases with repeated use. By contrast, social notifications targeted at the core-circle social contacts have a lasting effect.
