We develop a model of interlocking bilateral relationships between upstream manufacturers that produce differentiated goods and downstream retailers that compete imperfectly for consumers. Contract offers and acceptance decisions are private information to the contracting parties. We show that...

While vertical integration is traditionally seen as a solution to the hold-up problem, this paper highlights instead that it can generate hold-up problems — for rivals. We first consider a successive duopoly where competition among suppliers eliminates any risk of hold-up; downstreamfirms thus...

We develop an agency model of organized crime accounting for the main trade-offs involved by the introduction of an accomplice-witness program. We characterize the optimal policy and identify its main determinants in a framework where public officials can be dishonest. Our predictions are tested...

We examine the impact of the licensing policies of one or more upstream owners of essential intellectual property (IP hereafter) on the variety offered by a downstream industry, as well as on consumers and social welfare. When an upstream monopoly owner of essential IP increases the number of...

We study how career concerns affect the dynamics of incentives in a multi-period contract, when the agent’s productivity can evolve exogenously (random shocks) or improve endogenously through investment. We show that incentives are stronger and performance is higher when the contract...

Large retailers, enjoying substantial market power in some local markets, often compete with smaller retailers who carry a narrower range of products in a more efficient way. We find that these large retailers can exercise their market power by adopting a loss-leading pricing strategy, which...

This paper examines whether retailer bargaining power and upfront slotting allowances prevent small manufacturers (who have no bargaining power) from obtaining adequate distribution. In contrast to the findings of Marx and Shaffer (2007), who showed that all equilibria involve limited...

We study the effect of encouraging private actions for breaches of competition law. We develop a model in which a plaintiff, who may have private information about whether a breach of law has been committed, decides whether to open a case against a defendant. If opened, the case may be settled...
