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.

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 thesis focuses on how specific aspects of product differentiation affect economic outcomes through their impact on competition between firms. The first paper presents an analysis of firms' incentives to share information about the perceived profitability of different technologies prior to making an investment decision. The model is one of vertical product differentiation in which firms face uncertainty over consumers' preferred product. The main result is that firms reveal information only when they are sufficiently uncertain about which investment strategy to pursue. Information can be revealed in order to facilitate either coordination on a particular technology or anti-coordination on different technologies. In the second paper a seller can choose to sell one or several horizontally differentiated products from competing developers. Developers can charge the seller different wholesale prices for their products where prices are dependent on whether the seller will also carry a competing product. A higher consumer valuation of products raises the potential market share from a single product and thereby increases competition between developers. This implies developer profits can decrease in product quality. The model is compared to a situation in which developers compete for consumers without an intermediary seller. This comparison illustrates how developers sometimes can make higher profits by using a downstream seller since the seller's pricing response acts as a competition softener between developers. In paper three the focus is on product allocation through a single developer of several products who can decide how to allocate them among sellers. This model also features horizontally differentiated products but introduces multidimensional consumer preferences over products and sellers. The developer's product allocation decision is shown to be a key profit determinant for the supply chain. By distributing different products to each seller, the developer can focus inter-seller competition on the product dimension of consumer preferences. Distributing the same products to both sellers allows the developer to force sellers to compete in the dimension of consumers' seller preferences. The relative intensity of consumer preferences over products and sellers thereby determines a profit maximizing allocation for the developer.
