This lecture deals with third-degree price discrimination in both monopolistic and oligopolistic markets. The classical monopoly paradigm serves as a benchmark. Next, we move to an oligopoly setting, first with best-response symmetry, then with best-response asymmetry. We end with behavior-based...

We examine the profitability and the welfare implications of pricediscrimination in two-sided markets. Platforms have information aboutthe preferences of the agents that allows them to price discriminatewithin each group. The conventional wisdom from one-sided horizontallydifferentiated markets...

A rather neglected issue in the tax competition literature is the dependence of equilibrium outcomes on the presence of firms and shoppers (two-sided markets). Making use of a model of vertical and horizontal differentiation, within which jurisdictions compete by providing public goods and...

We examine the incentives and implications of supplier encroachment, when final good produc-tion requires the use of multiple complementary inputs and the entry of a supplier into the final good market gives rise to mutual outsourcing of inputs between the encroaching supplier and the incumbent....

We study how an incumbent patent holder can use its licensing policy strategically to reduce the threat of further entry. The patent holder can license its technology to another incumbent firm via a low royalty. This licensing strategy makes the terms of future licensing agreements less...

We employ the assignment game of Shapley and Shubik (1972) to study the endogenous matching patterns in a market that consists of heterogenous principals and agents. We show that, in general, the equilibrium matching is non-assortative. We then characterize the equilibrium relationship between...
