In a hub-and-spoke network, the profit function of an airline is supermodular with respect to the airline's own entry decisions for different city-pairs. This source of complementarity implies that a hub-and-spoke network can be an effective strategy for deterring the entry of competitors. This paper presents an empirical dynamic game of airline network competition that incorporates this entry deterrence motive for using hub-and-spoke networks. We summarize the results of the estimation of the model, with special attention to empirical evidence regarding the entry deterrence motive.

This book reviews recent progress in the theory of oligopoly and market leadership and provides new results on the theory of Stackelberg competition and Nash competition with strategic investment under endogenous entry. These theories are applied to models of competition in quantities, prices and to patent races. The results are used to propose a new approach to competition policy and issues of the abuse of dominance.

This cohesive collection brings together David J. Teece's most important work on the nexus of innovation and competition policy. He was one of the first to flag the importance of innovation issues to competition policy 25 years ago. He has also pioneered the application of economic and organizational principles to issues in the management of innovation. Throughout these essays, Professor Teece shows how technological advances, the advent of the Internet and other recent shifts in the global business landscape have placed businesses in a radically altered situation from even just a few decades ago. He clearly elucidates the need for both businesses and policymakers to adapt to this rapidly evolving landscape by embracing and fostering next-generation competition policies. Topics discussed include antitrust policy, technology strategies, competition policy, market power and intellectual property issues. Students and professors of business and management, innovation studies, intellectual property and competition lawyers will find this volume a critical asset to their work. Policymakers and regulators will also benefit immensely from this lucid and comprehensive collection.
