This paper analyzes platforms and rejections in two-sided markets with network externalities, using the specific context of a payment card association. We study the cooperative antitrust determination of the interchange fee by member banks. We use a framework in which banks and merchants may...

Using a simple downstream duopoly model with vertical relations and downstream R&D, we investigate the effect of non-assertion of patents (NAP) provisions. A monopoly upstream firm decides whether to employ NAP provisions. If it does so, it freely incorporates the R&D outcomes into its inputs....

Abstract This study attempts to organize the regulatory perspective on the interaction between information law and competition law, especially for platform businesses. An online platform is an entity that mediates multiple groups of users, such as providers and users of products, services, and...

Abstract This study examined the reasons for the decline in the plaintiff win rate in medical lawsuits in Japan since 1999. The results suggest that the decline in the plaintiff win rate is likely due to the overall shortening of trial periods. In particular, if the trial period is shortened by...

This paper constructs a model of anticompetitive exclusive dealings with potential downstream competition. Unlike in previous studies, the incumbent can establish a direct retailer with some fixed payment and can offer an exclusive contract to a downstream buyer twice. We show that the existence...
