We present a model of vertical contracts between manufacturers and retailers with nonlinear pricing strategies. Using home-scan data on bottled water produced by manufacturers and sold by retail chains in France, we estimate a structural demand and supply model allowing for two-part tariff...

This article reviews the recent literature on regulation under asymmetric information. We first develop the conceptual framework and offer a reminder of the techniques used in the field. Then we apply the framework and techniques to a variety of situations -- with or without commitment. We...

We develop a framework for Internet backbone competition. In the absence of direct payments between websites and consumers, the access charge allocates communication costs between websites and consumers and affects the volume of traffic. We analyze the impact of the access charge on competitive...

Firms sometimes try to "poach" the customers of their competitors by offering them inducements to switch. We analyze duopoly poaching under both short-term and long-term contracts assuming either that each consumer's brand preferences are fixed over time or that preferences are independent over...

This article extends the theory of network competition by allowing receivers to derive a surplus from receiving calls and to affect the volume of communications by hanging up. We investigate how receiver charges affect internalization of the call externality. When the receiver charge and the...

We analyze platforms in two-sided markets with network externalities, using the specific context of a payment card association. We study the cooperative determination of the interchange fee by member banks. The interchange fee is the ``access charge'' paid by the merchants' banks (the acquirers)...

This article considers a two-period model of natural monopoly and second-sourcing. The incumbent supplier invests in the first period. After observing the incumbent's first-period performance, the buyer may break out in the second period. The investment may or may not be transferable to the...

We evaluate the competitive and governance effects of "duality." Duality refers to the joint membership (e.g., by banks) in competing associations or joint ventures (e.g., Visa and MasterCard). We first show that the not-for-profit nature of the associations along with the usage-based fees they...

We study monopoly pricing of overlapping generations of a durable good. We consider two sorts of goods: those with an active secondhand market and anonymous consumers, such as textbooks, and those with no secondhand market and consumers who can prove that they purchased the old good to qualify...
