We study how net neutrality regulations affect high-bandwidth content providers investment incentives in quality of services (QoS). We find that the effects crucially depend on network capacity levels. With a limited network capacity, the prioritized delivery services are complements to content...

This paper empirically investigates the effect of international simple resale (ISR) authorization on the prices for international message telephone service (IMTS). We compile a firm-level panel data set for over 200 United States-foreign country bilateral markets from 1995 to 2004. These data...

We consider platform competition in the presence of small users and a usergroup. One platform enjoys a quality advantage and the other benefits from favorable beliefs. We study whether the group mitigates the users' coordination problem i.e., joining a low-quality platform because they believe...

When platforms compete for consumers, two types of consumer heterogeneity will matter: consumers value the presence of other consumers on a platform differently, and consumers contribute to the value of the platform differently.

This paper analyzes the effects of tying arrangements on market competition and social welfare in two-sided markets when economic agents can engage in multi-homing; that is, they can participate in multiple platforms in order to reap maximal network benefits. The model shows that tying induces...
