My dissertation features three essays in industrial organization. The first two investigate aspects of potentially anticompetitive firm behavior in differentiated product markets. Contrary to previous analyses, requirements tying and bundled rebates by a firm with a monopoly in one market that competes in another may increase total surplus when product differentiation in the competitive market is endogenous. This result is stronger for tying than for bundled rebates, and holds for both horizontal and vertical differentiation (essays 1 and 2, respectively). Under requirements tying or bundled rebates, a multiproduct firm (horizontally) differentiates its product less from its rival's product than it would under independent pricing, suggesting a new efficiency consideration for requirements tying: a reduction in transport costs. A similar result prevails under vertical differentiation: when the tying firm controls either quality niche, it reduces the quality of its tied product; however, the rival may invest in the quality of its competing product. Hence, the effect on total surplus is ambiguous when tying or bundled rebates arrangements are permitted. The second essay employs an empirical model typically used to analyze differentiated product markets analyze a different economic environment: parents' decision to home school their children. Home schooling has grown in popularity as an alternative to public or private schools; some estimates place growth at 15 to 40% per year in the U.S. I empirically estimate the demand for home schooling as an alternative to these other modes of education, focusing on potential network effects in household decisions to home-school. I find support for the hypothesis that home schooling 'support groups' mitigate the cost of home schooling relative to the alternatives, but only occur in areas with a critical mass of home-schooling households. The data also suggest that as interest in home schooling grows, the local community's school district spending per child declines, increasing the probability that more parents will take their children out of public schools. Both phenomena suggest the existence of network effects in the market for primary and secondary education. / text

This dissertation comprises three essays on theoretical and empirical issues in industrial organization. Chapter 1 outlines the issues explored in the subsequent chapters and briefly describes their conclusions. Chapter 2 explores how product differentiation impacts the incentive compatibility condition for firms to sustain implicit collusion in games of repeated interaction where, in contrast to previous studies, I focus on a market which is simultaneously vertically and horizontally differentiated. To achieve this objective, vertical differentiation is incorporated into an otherwise standard Hotelling framework. The ensuing mixed model of differentiation shows how the interrelationships between both forms of differentiation impact the incentives to collude, and is more general since it replicates previous findings throughout the literature. In Chapter 3, a multiproduct oligopoly model admitting product differentiation and a discrete choice demand model are proposed and estimated to determine if patterns of anti-competitiveness exist across distinct segments of the European car market. This chapter focuses on the evolution of price competition at a finer level than has been studied with a view to empirically challenge the notion that the European car market is wholly anti-competitive. Empirical results show that firm conduct varies due to the intensity of within-segment competition among rival firms. There is evidence of softer competition in the larger, mid- to full-sized segments and more aggressive competition in the smaller, entry-level subcompact segment. Chapter 4 represents a formal extension of the analysis in Chapter 3. In this chapter I examine the competitive structure of the U.S. automobile market using proprietary data comprising actual dealer-level transaction prices of several models of cars and light trucks sold in the domestic U.S. market between 2004 and 2007. The chapter is the first such study to employ consumer end-prices for automobiles in a structural New Empirical Industrial Organization (NEIO) framework. Empirical results reveal that there is more aggressive pricing in the light truck segments comprising minivans/SUVs and pickups, Bertrand pricing in the smaller, entry-level car segments, and softer competition in the full-size car segment. There is also a strong preference for domestically produced light trucks although consumers generally prefer to drive fuel efficient vehicles. / Ph. D.
