Book Description
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.

Book Description
This dissertation explores models of heterogeneous product markets that rely on the "vertical product differentiation" formulation. The demand structure applied here is the covered-market configuration under the vertical product differentiation. With this specification, product market equilibria of the monopoly and duopoly market are derived. In particular, parameter restrictions on the degree of relative consumer heterogeneity associated with the covered-market setting are identified and used to interpret analytical results. Based on the specified demand structure, I revisit two industrial organization topics from the perspectives of vertical product differentiation. The first essay analyzes the entry of a new product into a vertically differentiated market where an entrant and an incumbent compete in prices. Many models on strategic entry deterrence deal with "limit quantities" as the established firm's strategic tool to deter or accommodate entry. Here, however, the entry-deterrence strategies of the incumbent firm rely on "limit qualities". With a sequential choice of quality, quality-dependent marginal production cost, and a fixed entry cost, I relate the entry-quality decision and the entry-deterrence strategies to the level of an entry cost and the degree of consumer heterogeneity. In particular, the incumbent influences the quality choice of the entrant by choosing its quality level before the entrant. This allows the incumbent to "limit" the entrant's entry decision and quality levels. Quality-dependent marginal production costs in the model entail the possibility of inferior-quality entry as well as the incumbent's aggressive entry-deterrence strategies by increasing its quality level towards potential entry. Welfare evaluation confirms that social welfare is not necessarily improved when entry is encouraged rather than deterred. The second essay is motivated by some specific economic questions that have arisen with the introduction of 'genetically modified' (GM) agricultural products. A duopoly market-entry model associated with the vertical product differentiation is developed to show how the existence of segregation costs biases the firm's quality choice behavior. Thus, the key factor of the model is the cost of segregation activities that are necessary to distinguish GM products from non-GM products. With an increasing and convex cost of quality, the model predicts that the entrant firm has an increased incentive to enter the market with a low-quality good to reduce production costs if segregation costs are sufficiently high. When consumers are homogeneous enough, however, entry may occur with the high-quality good.

Book Description
This thesis develops computational and applied tools to study differentiated products. The core of the thesis focuses on Berry, Levinsohn, and Pakes's [1995] (BLP hereafter) model of differentiated products. First, I examine how polynomial-based methods for multi-dimensional numerical integration improve the performance of the model. Unlike Monte Carlo integration, these rules produce reliable point estimates and standard errors as well as increasing the accuracy and execution speed of the estimation software. Next, I conduct a large scale simulation study to investigate both the asymptotic and finite sample behavior of the BLP model using the traditional instruments formed from characteristics of rival goods and also supply-side cost shifters, which are necessary for asymptotic identification. The final part of the thesis evaluates the 2003 merger of Morrisons and Safeway by combining a discrete/continuous choice model of demand with census data to construct a geographic distribution of demand. I use this distribution to model the interaction between the location of consumers and stores, focusing on the welfare implications of the merger.
