Book Description
Essay one examines whether a generalized version of Flam and Helpman's (1987) model of vertical differentiation can reconcile three facts. One, countries import only a subset of available varieties. Two, import prices vary across exporters within narrow product categories. Three, US growth in both import variety and import price dispersion has occurred at the same time that the US income distribution has significantly widened. The generalized model maps cross-country differences in income distributions to variation in import variety and price variation. The theoretical predictions are examined and confirmed using panel data on import variety and prices, and detailed income distribution data from the Luxembourg Income Survey. Country pairs whose income distributions are growing more similar over time have growing similarity in the distribution of their import prices, and in the number of common export sources from which they buy. Essay two investigates the theoretical relationship between factor abundance and within-product specialization. To address the issue, we develop a general equilibrium model that shows the relationship between quality/quantity specialization and factor endowments. On the quality demand side, we employ a modified CES utility function to explicitly take into account the consumer's preferences for quality. Quality supply side is modeled by introducing a quality differentiated intermediate goods. The model can perfectly explain the couple of recent important empirical findings (Schott 2004, Hummels and Klenow 2005). One, within-product qualities are positively correlated with capital abundance. Two, capital- (labor-) abundant countries produce higher (lower) qualities in smaller (larger) quantities within a product.

Book Description
This Thesis presents three essays in the area of strategic trade theory and policy. The first essay presents an analysis of trade and welfare between countries with asymmetric conditions. A two-period two-country address model of product differentiation is examined in which firms face an initial period of autarky. Trade takes place in the subsequent period and firms fully anticipate switches in trade regimes. Results suggest that historical (domestic) conditions matter a lot on the international market place. Firms that come from countries with a larger market tend to develop longer product lines, which puts that country in a dominant position in international competition. The model is also used to analyse gains/losses from trade in relation to country size. The second essay investigates the differential effects of specific and ad-valorem tariffs on quality, price and welfare in an oligopolistic industry consisting of foreign and domestic firms. These effects are shown to depend on the location of the home and foreign firms in the quality spectrum. Both tariffs are ranked and conditions for either tariff to be welfare superior are derived. Finally, the third essay presents an analysis of trade policy with endogenous market structure. A "third market model" is specified. Using a simple framework in which industry structure is derived endogenously as the outcome of product line decisions by firms, we show that governments have an incentive to affect the equilibrium product composition by setting non-zero subsidy rates in order to maximize domestic welfare. Subsidies may be uniform or non-uniform across goods and the optimal policy exhibits strong discontinuities as domestic welfare maximization implies a switch of regimes.

Book Description
Product quality plays an important role in determining international trade flows. Its level is related to product unit value, characteristics of importing countries, and many other key variables in trade. In this dissertation, we study product quality and its role in various trade topics. In the first chapter, we study its role in price markup and how it is related to the importing countries' income. In the second chapter, we study multi-product firm's decision on exporting the top and the bottom qualities and the range of quality ladder facing different destination markets. In the last chapter, we study how a firm's offshoring decision is related to the quality of final product, the probabilities of making mistakes, the wage difference, and the size of the economy. We will describe each chapter in detail in the following paragraphs. We believe this dissertation complements current literature on product quality and tradein the areas of price markeup, multi-product firm behavior, and offshoring decision. In the first chapter, we begin by documenting the price discrimination practice based on destinations' per-capita income levels from the automobile industry. It is found that low-quality model manufacturers practice price discrimination while high-quality model manufacturers set price more uniformly across destinations. A highly tractable model was developed to capture these different practices of pricing strategies by including the distribution cost in the firm's decision. Each firm in the model simultaneously chooses quality and price to maximize its profits. The model predicts that highly productive firms not only produce higher quality products, but also price their products more uniformly across destinations. An extension of the model that features consumer income inequality predicts that products are sold at higher prices in countries with high income inequality. This result reconciles observations of high prices found in some developing countries such as China. Empirical results support the model's two key predictions: firms with higher productivity price their products more uniformly; and countries' income inequalities affect price positively.The second chapter is motivated by the stylized fact that not all vertically differentiated car models are sold sold in each country. Furthermore, the number of car models sold in each country appear to be systematically affected by destination market's conditions. To study this stylized fact of multi-product firm's decision on quality products, we use a model where firms simultaneously determine optimal prices and the range of quality products. It is found that the top and bottom qualities and the length of the quality ladder are affected systematically by various firm's and market's conditions. The empirical results using European car data from 1993-2011 supports the key predictions in the model.In the last chapter, we are interested in studying firm's offshoring decision and how it is related to product quality. In recent years, the highly intensified and diversified global offshoring activities have been accompanied by some onshoring activities led by large U.S. manufacturing companies. To address this stylized fact, we started with a value-chain offshoring model with product quality specification. Besides the wage difference between countries, the model assumes that each country has a probability of making mistakes. It is found that the range of tasks processed in offshoring destination is related to the probabilities of making mistakes, the wages, and the size of the economies. Increasing the quality of final product, however, does not change the range of products being offshored which implies an onshoring activity. Following the theoretical model, we use the trade data in China from 1998-2013 in the empirical model and confirm the key predictions in the theoretical model. This chapter contributes to current offshoring literature by addressing the product quality specification, the onshoring activities, and identifying the effect of making fewer mistakes on the range of products offshored.

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.
