In nonlinear pricing environment with correlated types, we characterize optimal selling mechanisms when buyers could form a coalition to coordinate their reports and to arbitrage on the goods. We find that when the types of agents are weakly positively correlated, the optimal weakly...

The present paper provides a descriptive analysis of the second-degree price discrimination problem on a monopolistic two-sided market. By imposing a simple two-sided framework with two distinct types of agents on one of its market sides, it will be shown that under incomplete information, the...

We study general discrete-types multidimensional screening without any noticeable restrictions on valuations, using instead epsilon-relaxation of the incentive-compatibility constraints. Any active (becoming equality) constraint can be perceived as "envy" arc from one type to another, so the set...

This paper aims to relate the principles of Ronald Coase Theorem with negative impacts of biotechnology, taking cases of specific research groups and medium-sized companies in biotechnology. We consider an application of economic theory on transaction costs (TEC) provides a good foundation for...

We study a tractable two-dimensional model of price discrimination. Consumers combine a rigid with a more flexible choice, such as choosing the location of a house and its quality or size. We show that the optimal pricing scheme involves no bundling if consumer types are affiliated. Conversely,...

This paper considers the screening problem faced by a monopolist of a network good in a general setting. We demonstrate that the joint presence of asymmetric information and network externalities revise the "no distortion on the top" and "one-way distortion" principle. The pattern of consumption...

In developing countries, empirical evidence suggests that labor unions entail a positive wage gap for unionized workers, in particular in monopolistic and publicly controlled firms. In this paper, we analyze how the presence of a labor union affects the regulation of a monopoly under asymmetric...

This paper provides a new explanation for the dominance of the low-powered incentive contract over the high-powered incentive contract using a mixed model of moral hazard and adverse selection. We first show that the power of incentives in the second-best contract is lower than that in the...

This paper considers an entry-deterring nonlinear pricing problem faced by an incumbent firm of a network good. The analysis recognizes that the installed user base/network of incumbent monopolist has preemptive power in deterring entry if the entrant’s good is incompatible with the...

This paper studies the cost requirement for two-agent collusion-proof mechanism design. Unlike the existing results for general environments with three or more agents, it is shown that collusive behavior cannot be prevented freely in two-agent nonlinear pricing environments with correlated...
