In many circumstances, a principal, who wants prices to be as low as possible, must contract with agents who would like to charge the monopoly price. This paper compares a Demsetz auction, which awards an exclusive contract to the agent bidding the lowest price (competition for the field) with...

This paper investigates the role of product upgrades and consumer switching costs in the tying of complementary products. Previous analyses of tying have found that a monopolist of one product cannot increase its profits and reduce social welfare by tying and monopolizing a complementary product...

The viatical settlement industry provides an opportunity for terminally-ill consumers, typically HIV patients, to exploit a previously untapped source of equity in existing life insurance contracts to finance consumption and medical expenses. The 1996 introduction and dissemination of effecive...

This paper studies optimal fiscal and monetary policy under imperfect competition in a stochastic, flexible-price, production economy without capital. It shows analytically that in this economy the nominal interest rate acts as an indirect tax on monopoly profits. Unless the social planner has...

Multi-sector sticky price models have surprising implications when durable goods have flexible prices. While in actual data the production of virtually all durables exhibits strong negative responses to monetary contractions, in dynamic general equilibrium models a monetary contraction causes...

Recent literature notes that when quality is produced with fixed costs, a high quality firm can undercut its rival's prices and may find it profitable to invest more in quality as market size grows large. As a result, a market can remain concentrated even as it grows large. When quality is...

Previous work has claimed that monopoly power facilitates the provision of credit, since monopolists are better able to enforce payment. Here, we argue that if relationship-specific investments are required by borrowers to establish creditworthiness, monopoly power may reduce credit provision...

Since bank deposits and currency are substitutes and banks have monopoly power, higher nominal interest rates lead to higher deposit spreads. This raises the cost of transaction services, increases bank profits and attracts entry into the banking sector. Taking these effects into account, a one...

When an upstream monopolist supplies several competing downstream firms, it may fail to monopolize the market because it is unable to commit not to behave opportunistically. We build on previous experimental studies of this well-known commitment problem by introducing communication. Allowing the...

Standard policies to correct market power and selection can be misguided when these two forces co-exist. Using a calibrated model of employer-sponsored health insurance, we show that the risk adjustment commonly used by employers to offset adverse selection often reduces the amount of...
