This article investigates how the use of contracts that condition discounts on the share a supplier receives of a retailer's total purchases (market-share contracts) may affect market outcomes. The case of a dominant supplier that distributes its product through retailers that also sell...

type="main" <p>We introduce a flexible model of telecommunications network competition with nonuniform calling patterns, accounting for the fact that customers tend to make most calls to a small set of similar people. Equilibrium call prices are distorted away from marginal cost, and competitive...</p>

We analyze the short- and long-run implications of third-degree price discrimination in input markets. In contrast to the extant literature, which typically assumes that the supplier is an unconstrained monopolist, in our model input prices are constrained by the threat of demand-side...

We consider a monopolistic supplier's optimal choice of two-part tariff contracts when downstream firms are asymmetric. We find that the optimal discriminatory contracts amplify differences in downstream firms' competitiveness. Firms that are larger-either because they are more efficient or...

We analyze up- and downstream market structure and the choice of technology in a bilaterally oligopolistic industry. The distribution of industry profits between up- and downstream firms is determined by a procedure of bilateral negotiations, which is shown to generate the Shapley value....

We examine the effect of competition for scarce corporate financial resources on managers' incentives to generate profitable investment opportunities. Operating an active internal capital market is unambiguously beneficial only if divisions have the same level of financial resources and the same...

We show that in contrast to results in the extant literature, single sourcing may not be the optimal strategy of a buyer facing suppliers with strictly convex costs. As we argue, previous findings relied crucially on the joint assumption that, first, there is only a single buyer and that,...
