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
My dissertation consists of three chapters in each of which I analyze how specific phenomena affect market competition and the firms' strategic decisions. Below I briefly describe the findings of each chapter. The first chapter analyzes a situation where a firm's customers learn some unanticipated or hidden use value of the firm's product whereas the non-customers remain uninformed about that extra value. Should the firm advertise and inform all consumers about its product's hidden value? A monopolist will benefit from advertising its product's hidden value. However, our analysis reveals that this may not be true when the firm faces competition in the market--the firm may actually make higher profits if it keeps its hidden value secret from its competitor's customers even if advertising to inform those customers is costless. Not advertising the product's hidden value creates an incentive for both firms to continue targeting their own existing customers rather than poaching each other's customers. This can alleviate price competition and increase both firms' profits even when firms anticipate the hidden value and compete more aggressively for customers in the early period. Our research suggests that firms can benefit from an "under-promise and over- deliver" strategy if they refrain from communicating their extra value to the competitor's customers. Moreover, we find that positive word of mouth about a firm's product will not necessarily benefit the firm and can in fact make all firms worse off. The second chapter of the dissertation challenges the conventional wisdom that firms will always benefit from reduced competition if their competitor exits the market or has a weakened product offering. We show that in a channel setting such intuition may not be true, and a manufacturer and its retailer can actually become worse off if the competing manufacturer exits the market (e.g., because of idiosyncratic shocks in its supply-side factors). Put differently, more intense market competition can be an all-win for the manufacturers, the retailers, and the consumers. Intuitively, although the competitor's exit will alleviate price competition for the surviving manufacturer and retailer, it will also worsen the double-marginalization problem within the surviving manufacturer's channel, leading to lower profits for the surviving manufacturer despite an increase in its wholesale price. The retailer may also become worse off because its benefit from alleviated competition may not be enough to compensate for the increased wholesale price. Moreover, we find that the manufacturer may benefit when the competitor's product quality increases, i.e., a firm may prefer a stronger rather than a weak enemy. In the third chapter, we investigate the competitive implications of some consumers' concerns for price fairness--a phenomenon that has been well-documented in the behavioral literature. We analyze a market where a fraction of consumers have fairness concerns, and their fairness perceptions are formed by comparing the competing firms' price markups--if a firm charges a higher markup than its competitor, then "fair-minded" consumers will tend to perceive the firm as unfair and be less willing to purchase the firm's product. One might think that the existence of fair-minded consumers would induce the firms to reduce their prices, decreasing their profits and increasing consumers' surplus. Contrary to this conventional wisdom, our analysis reveals that having a segment of fair-minded consumers in the market has a non-monotonic effect on the firms' profits. More specifically, if the fraction of consumers having fairness concerns is small, consumers' fairness concerns can actually alleviate price competition, making firms better off and consumers worse off. Within that range, an increase in the fraction of fair-minded consumers can increase the firms' profits and reduce the consumers' surplus. But when the fraction of fair-minded consumers is sufficiently high, the firms will compete more aggressively, in which case consumers' fairness concerns will benefit consumers and reduce the firms' profits.

Book Description
"Cournot (1838), Bertrand (1883), and Stackelberg (1934)'s models of strategic interaction between competing firms have become the primary workhorses for the analysis of imperfect competition, being employed in a variety of fields, notably industrial organization and international trade. Among others, Anderson and Engers (1992) have argued that the simultaneous-move Cournot model is applicable to characterize an industry where lags in the observation of output decisions are long, whereas the sequential-move Stackelberg model applies when the reverse holds. While many industries fit the Cournot framework better, Shinkai (2000) has argued that the DRAM market (i.e., the market for the main memory component of most computers and many electronic systems) is better described by the Stackelberg model because firms make sequential capacity choices in an irreversible manner. It is important to understand how the implications of the these models differ with respect to total output, welfare and producer surplus for at least two reasons. First, such an understanding provides insights into the mechanics of these important theoretical models. Relatedly, it also helps us in deciding which framework (if either) is more appropriate for studying a given industry given the observed price and output levels. Second, once it has been decided which model better captures the characteristics of a given industry, a policy maker can better assess whether mergers or other industry developments may help or hurt consumers. The answer may very well depend on which model one thinks is more appropriate to describe an industry. In Chapter 1 of my thesis, I compare an n-firm Cournot game with a Stackelberg model, where n firms choose outputs sequentially, in a stochastic demand environment with private information. The Stackelberg perfect revealing equilibrium expected price is higher, therefore expected output and total surplus are lower; total expected profits are higher than in Cournot equilibrium irrespective of how noisy both the demand shocks and private demand signals of firms are. These rankings are the opposite to the rankings of prices, total- output, surplus, and profits between Cournot and Stackelberg models under perfect information. In the second part of Chapter 1, I also extend the analyses of Gal-Or (1987) and Shinkai (2000) on last-mover advantage to the above n-firm Stackelberg oligopoly set-up. I show that at the perfect revealing equilibrium, the first n - 1 firms' expected profits form a decreasing sequence from the first to the (n - 1)st. If, in addition, there are no more than four firms, then the last mover earns the highest expected profit. We explain these results by discussing strategic substitutability and complementarity relationships among the quantity decisions of firms. We use the fact that there is a discontinuity between the Stackelberg equilibrium of the perfect information game and the limit of Stackelberg perfect revealing equilibria of the incomplete information games as the noise of the demand information vanishes to zero. It is in Chapter 2 that I study the applications of Cournot and Bertrand models to mergers. I investigate the welfare effects of mergers on merging firms (insiders), non-merging firms (outsiders), and consumers in a differentiated product market. I extend many results in this literature by both considering imperfect substitution (and complementarity) among goods and varying the number of firms merged. If mergers do not generate any cost efficiencies, then any size of horizontal mergers among firms producing substitutable goods decreases both consumer and total welfare under both quantity and price setting games. Moreover, horizontal mergers with full cost efficiency gains are still mostly welfare reducing especially when the cost-demand ratio is sufficiently low. However, any size of conglomerate merger among suppliers of complementary products are both consumer and welfare enhancing under both game settings. I also introduce a price approach for calculating total welfare to identify the effects causing these results. In both Chapters 1 and 2, the common assumption was that all firms actively produce. However, in several markets some firms are not able to actively participate, and many decide to shut down. A cost reducing innovation by competitors, the inability to adapt changing market conditions, a cost-efficient merger among rival firms, or an increase in fixed costs may increase the incentives of a firm to exit from the market. In line with these concerns, we relax the assumption of positive production by all firms and allow firms to not produce. It is well known that the theorems that state the existence and uniqueness of Cournot equilibrium would straightforwardly extend to environments where firms prefer to be not active. However, in Chapter 3, we argue that when firms are allowed to charge their marginal costs, Bertrand models lead to very unexpected results. We show that differentiated linear Bertrand oligopolies with constant unit costs and continuous best replies do not need to satisfy supermodularity (Topkis (1979)) or the single crossing property (Milgrom and Shannon (1994)). In particular, Bertrand best replies might be negatively sloped and there are (infinite) multiple undominated Bertrand-Nash equilibria on a wide range of parameter values when the number of firms is more than two. These results are very different from the existing literature on Bertrand models, where uniqueness, supermodularity, and single crossing usually hold under a linear market demand assumption and best reply functions slope upwards. We further provide an iteration algorithm to find the set of players that are active in any equilibrium. This set is uniquely defined. We also characterize the whole set of undominated equilibria"--Pages v-viii.

Book Description
Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

Book Description
This dissertation contains two essays on the aggressive behavior of corporations in product market competition. In the first essay, I investigate how market structure can impact a firm's risk of facing predation by rivals, and hence, its financial policy decisions. Using a simple model, I demonstrate that a firm faces a greater predation threat when it meets the same competitor in many markets, as this competitor is able to internalize more of the benefit, degrading the firm's ability to compete in the future through aggressive actions today. I then test the predictions of the model using 2003-2011 panel data on store location across retail store chains in the US. I find that firms tend to expand more aggressively in markets shared with a competitor experiencing a substantial increase in leverage, or a decline in a credit rating, when they face that competitor in more of the other markets. The expansion relationship was found to be stronger in data from the 2008-2009 financial crisis, a period when difficulty in rolling over or obtaining new debt made it especially hard for weak firms to absorb losses. I also show that a firm facing the same competitors in many markets choose lower levels of leverage and that it decreases that leverage when a merger in the industry increases the amount of competitive overlap it has with other firms. These results suggest that firms are aware of the predation risk due to a competitive overlap and select financial policies to minimize this risk. In the second essay, I study the impact of internally generated funds on product market competition. More specifically, I investigate the idea that firms compete aggressively when their competitors face cash flow shortfalls. Testing this idea is challenging because competitor's cash flow changes are potentially endogenous with respect to firm's behavior. I address this problem in three ways. First, I investigate firm's reaction in a given market when its competitors face cash flow shortfalls outside of that market; this analysis is conducted using store location data on retail store chains. Second, I focus on the 2008-2009 financial crisis period in which retail store chains were hit by a negative demand shock which was hardly expected ex ante. Finally, I use a shock to local economic conditions which varies across markets and the different distributions of store locations across firms as instruments for the changes in competitors' cash flows. I find that a firm expands more in a given market in which it competes with rivals which face a more negative cash flow shortfall in the other markets. This relation is stronger when the competitors were highly leveraged before the crisis. Finally, I illustrate evidence that a firm responds more aggressively to competitor's cash flow shortfalls if it competes with that competitor in many of the same markets; this result is consistent with the prediction of the model in Chapter 1. These essays contribute to the literature by adding new evidence on the predatory behavior of corporations in product market competition.

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.

Book Description
This dissertation consists of three essays on product quality and pricing. Essay 1: Pricing and Quality Provision in a Channel: A Model of Efficient Relational Contracts The first essay analyzes how quality concerns affect relationships in a channel. A firm concerned about uncontractible quality for a customizable good has to pay higher prices to sustain a relationship with the supplier. If the customizable good has very volatile demand, premium payments on this good cannot be sustained. Instead, the downstream firm pays a premium for a good with more stable demand that is correlated with demand for the customizable good. I use a novel dataset containing sales made by a wholesaler to Asian restaurants in the Southeastern United States to test this prediction empirically. As predicted by the proposed model, if customizable goods have very volatile demand, the high end restaurants do not pay a premium on those goods but instead pay a premium for other goods with more stable demand. Essay 2: Third Party Marketing Approvals The second essay measures the effect of competition in a certifier market. When customers purchase new products, there is often a degree of uncertainty about their quality. A common solution is to rely on a third-party certifier to provide some form of accreditation that signals quality. However, the incentives of a third-party certifier may not be completely benign. Competitive certification markets may lead the certifiers to provide unduly positive evaluations of quality to gain market share or provide unduly negative evaluations in order to gain credibility with end-users. This paper exploits an unusual natural experiment to evaluate the extent to which third-parties can be relied upon to correctly report product quality. It focuses on the FDA's decision to allow third parties to prepare certifications for certain medical devices, and observes how this decision to introduce competition at the reviewer stage has affected the quality of products allowed to go to market. There is evidence that allowing third party certification leads to significantly lower product quality. However, experience with using a third party reviewer in the past diminishes the negative effect of reviewer competition. Essay 3: Layaway and the Quasi-Endowment Effect of Installment Payments The third essay explores the quasi-endowment effect. The paper evaluates how much consumers are willing to prepay for a purchase which will be experienced in the future. In particular, the results indicate that prepaid installment plans allow the consumer to start deriving utility for the purchase from the moment of the first payment. This quasi-endowment effect is felt only for goods that are purchased for own consumption.

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
This dissertation consists of three essays on strategic and tactical issues in product design. The first essay presents a dynamic investment game in which firms that are initially identical develop assets which are specialized to different market segments. The model assumes there are increasing returns to investment in a segment, for example, due to word-of-mouth or learning curve effects. In equilibrium, firms that are only slightly different focus all of their investment in different segments, causing small random differences to expand into large permanent differences. Even though firms do not cooperate and do not make threats to punish each other, in the long run they divide the market, reaching the same outcome that they would if they cooperated to maximize joint profits. This second essay develops a model in which an incumbent has expertise in an old business format (e.g., running a full service airline), and a new firm enters the market with the possibility of using a new business format (e.g., running a "no frills" airline). Firms play a dynamic investment game in which the incumbent can invest in the new format and the entrant can invest in either format. If brand and format preferences are strong, and if it is easy to implement a format, then a firm already using one format does not invest in the other format, since such an attack would be met with swift retaliation. In this case, the entrant invests in the new format, while the incumbent avoids investing in order to retain the threat of investment as a punishment mechanism. The third essay shows that improved accuracy in conjoint analysis has important strategic implications. Even if two models provide unbiased part-worths, competitive game theory shows that the more accurate model (with lower error variance in an HB CBC model) implies that differentiation from competitors is more profitable. On the other hand, a less accurate model implies that each firm should forego differentiation and choose feature levels that provide customers the greatest utility (adjusting for marginal cost). I illustrate the theory by varying accuracy in a student-apparel application.
