We examine conditions under which a low cost vertically integrated manufacturer has an incentive to export an intermediate product to its higher cost (vertically integrated) rival rather than to vertically foreclose, fully cutting off supplies. The nature of supply conditions in the importing country, the size of an import tariff on the final good and optimal policy by the exporting country are all shown to be important for this decision. The exporting country may gain by taxing exports of the final (Cournot) product even though, under Cournot competition, an export subsidy is optimal in the absence of a market for intermediates. In this case, optimal policy also requires an export tax on intermediates, but the higher tax on final goods serves to divert sales to the more profitable market for intermediates increasing the extent of vertical supply. It is optimal to tax the export of both goods or to subsidize the export of both goods. It is never optimal to tax one and subsidize the other.

Law and Economics of Vertical Integration and Control focuses on the processes, methodologies, and approaches involved in the law and economics of vertical integration and control. The publication first elaborates on transaction costs, fixed proportions and contractual alternatives, and variable proportions and contractual alternatives. Discussions focus on sales revenue royalties, ownership integration, output royalties, important product-specific services, successive monopoly, advantages and limitations of internal transfers, and transaction cost determinants. The text then examines vertical integration under uncertainty and vertical integration without contractual alternatives. The book ponders on legal treatment of ownership integration and per se illegal contractual controls. Topics include tying arrangements, public policy assessment, resale price maintenance, vertical integration and the Sherman Act, market foreclosure doctrine, and the 1982 Merger Guidelines. The text also takes a look at contractual controls that are not illegal per se, alternative legal rules, and antitrust policy. The publication is a dependable reference for researchers interested in the law and economics of vertical integration and control.

The most controversial area in competition policy is that of exclusionary practices, where actions are taken by dominant firms to deter competitors from challenging their market positions. Economists have been struggling to explain such conduct and to guide policy-makers in designing sensible enforcement rules. In this book, authors Chiara Fumagalli, Massimo Motta, and Claudio Calcagno explore predatory pricing, rebates, exclusive dealing, tying, and vertical foreclosure, through a blend of theory and practice. They develop a general framework which builds on and extends existing economic theories, drawing upon case law, discussions of cases and other practical considerations to identify workable criteria that can guide competition authorities to assess exclusionary practices. Along with analyses of policy implications and insights applied to case studies, the book provides practitioners with non-technical discussions of the issues at hand, while guiding economics students with dedicated technical sections with rigorous formal models.
