This paper analyzes optimal cross-licensing arrangements between incumbent firms in the presence of potential entrants. The optimal cross-licensing royalty rate trades off incentives to sustain a collusive outcome vis-a-vis incentives to deter entry with the threat of patent litigation. We show...

This paper analyzes incentives of a multinational enterprise to manipulate an internal transfer price to take advantage of corporate-tax differences across countries under both monopoly and oligopoly. We examine “cost plus” and “comparable uncontrollable price” as two alternative...

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 develops a theory of patent portfolios in which firms accumulate an enormous amount of related patents in diverse technology fields such that it becomes impractical to develop a new product that with certainty does not inadvertently infringe on other firms' patent portfolios. We...

We provide a theoretical model of privacy in which data collection requires consumers' consent and consumers are fully aware of the consequences of such consent. Nonetheless, excessive collection of personal information arises in the monopoly market equilibrium which results in excessive loss of...

We explore how this trade-off affects the platform's referral fee and its own entry decision. We first characterize the platform's optimal...

This paper analyzes dynamic cartel formation and antitrust enforcement when firms operate in demand-related markets. We show that cartel prosecution can have a knock-on effect: desisting a cartel in one market reduces profits and cartel stability and leads to the break-up of the cartel in the...

This paper analyzes selection biases in the project choice of complementary technologies that are used in combination to produce a final product. In the presence of complementary technologies, patents allow innovating firms to hold up rivals who succeed in developing other system components....
