This article examines "consistent" conjectural variations in an oligopoly model with a homogeneous product. A conjectural variation is consistent if it is equivalent to the optimal response of the other firms at the equilibrium defined by that conjecture. When the number of firms is fixed, we...

We consider the incentives for oligopolistic manufacturers to adopt exclusive dealing. Manufacturers producing differentiated brands can choose to distribute through exclusive retail dealerships or nonexclusive dealerships. With nonexclusive dealing, manufacturers face an interbrand externality...

This paper generalizes a model of monopolistic competition attributable to Spence (1976). Firms produce symmetrically differentiated products with declining or U-shaped average costs. Free entry drives profits to zero in equilibrium. Spence finds that when firms behave "competitively," in a...

The buyer of a homogeneous input divides his input requirements into two contracts that are awarded to different suppliers. He uses a sequential second-price auction to award a primary and a secondary contract. With a fixed number of suppliers the buyer pays a higher expected price than with a...

We review the issues involved in designing a mechanism for allocating resource rights. We focus on the case of exploration and development rights for oil and gas leases in U.S. federal lands to highlight the tradeoffs at play. The main issues concern the design of the lease contract, the design...

Detection and deterrence of collusion are longstanding antitrust problems, made difficult because collusive arrangements are usually surreptitious. In this paper, I discuss factors that facilitate or inhibit collusive schemes, as well as circumstances where detection is possible. I describe how...

We describe the economics literature on auction markets, with an emphasis on the connection between theory, empirical practice, and public policy, and a discussion of outstanding issues. We describe some basic concepts, to highlight some strengths and weaknesses of the literature, and so...

This paper extends the theory of legal cartels to a.liated private value and common value environments, and applies the theory to explain joint bidding patterns in U.S. federal government o.shore oil and gas lease auctions. We show that e.cient collusion is always possible in private value...
