Abstract： With an explosive growth of the Internet, we have witnessed a significant expansion of social media platforms for creating and exchanging user-generated content during the past decade. On these platforms, users can view content for free and can post content voluntarily. Well-known examples of social media platforms include YouTube, Facebook, and Yelp. However, while these platforms play an important social role, the primary goal of platform owners is to maximize their profits.
In this talk, I consider a social media platform with user-generated content and operated by a profit-maximizing platform owner. I will talk about a class of payment schemes, in which the platform owner pays or charges content contributors per content view while the content is viewed for free by to content viewers. I model strategic interactions among the platform owner, content contributors, and content viewers as a two-sided market, while taking into account both content heterogeneity and content contributors’ competition for content views. In order to study the optimal payment rate for the platform owner, I analyze a three-stage game in which the platform owner sets a payment rate, content contributors decide whether to make contributions or not, and content viewers allocate their content views over the available content. The analysis suggests conditions under which the platform owner should pay or charge content contributors. I will conclude this talk by discussing the negative impact of payment on users’ social incentives to make content contributions and by discussing extension to other aspects of social media platforms such as energy consumption.
