We characterize equilibrium and efficient modes of production by comparing nested (vertical) outsourcing with horizontal outsourcing. Nested outsourcing is found to be inefficient unless the cost of monitoring outsourced production lines increases sharply with the number of subcontractors and...

In October 2011, new rules governing debit card interchange fees became effective in the United States. These rules limit the maximum permissible interchange fee that an issuer can charge merchants for a debit card transaction. This paper provides simple calculations that identify the...

We introduce three types of consumer recognition: identity recognition, asymmetric preference recognition, and symmetric preference recognition. We characterize price equilibria and compare profits, consumer surplus, and total welfare. Asymmetric preference recognition enhances profits compared...

We investigate how costly acquisition and exchange of customer-specific information affects industry profit and consumer welfare. Consumers differ in their preferences for competing brands and in their switching costs between brands. Brand-producing firms use their acquired knowledge of...

The paper investigates the reasons why person-to-person electronic funds transfers are still not very common in the United States compared with practices in many other countries. The paper also describes recent enhancements to online and mobile banking that provide account holders with low-cost...

The author constructs a theoretical model to examine the effects of an inherent conflict of interest between a seller of a house and the real estate broker hired by the seller. The model is then used to calibrate the broker's commission rates that would maximize the seller's expected gain. The...

The authors characterize equilibrium and efficient modes of production by comparing nested (vertical) outsourcing with horizontal outsourcing. Nested outsourcing is found to be inefficient unless the cost of monitoring outsourced production lines increases sharply with the number of...

We analyze history-based price discrimination in an asymmetric industry, where an incumbent, protected by switching costs, faces an entrant who does not have access to information about consumers' purchase histories. We demonstrate that consumer surplus is higher with uniform pricing than with...

This paper explains why payment card networks charge fees that are proportional to the transaction values instead of charging fixed per-transaction fees. We show that, when card networks and merchants both have market power, card networks earn higher profits by charging proportional fees. It is...
