Book excerpt: This thesis is a collection of three chapters, each representing an individual paper. The first chapter studies how the formation of supply chains affects economic growth. It provides a new tractable model for supply chain formation. The main innovation in this model is that, firms can choose suppliers to maximize profits. Individual firms' actions determine the equilibrium input-output network, and affect macroeconomic variables such as GDP. We then apply this model to understand the effect of changing supply chains on American productivity during the 1987-2007 period. The second chapter studies how a monopolist may sell multiple goods to strategic bidders. The monopolist may face a series of combinatorial constraints. For example, it may be forced to allocate at most one good to each bidder, and it may have additional constraints on which bidders can be allocated which goods. Furthermore, the monopolist does not know bidders' demand distributions. Rather, it only knows one sample from the demand distribution corresponding to each bidder. Nevertheless, by developing new online optimization algorithms, we show how simple mechanisms can approximate the monopolist's optimal revenue. Finally, the third chapter, develops a new model of firm optimization to understand how shrinking electronics have contributed to increased productivity and welfare in the United States, during the 2002-2017 period. In this model, firms face constraints on the size of the products they can build. As intermediate inputs, such as electronics, shrink, the firms' production possibilities frontier expands, and GDP increases.

Book excerpt: This dissertation contains three essays in Game Theory and Network Economics. The First Chapter studies how economic networks are formed. Random networks occur in many economic situations, such as transactions among financial institutions, trade between countries or social relationships. Network formation can be based on utility theory and translates into a game in a normal form. For this formation process, we derive a probability distribution over all networks. Further, we derive a test procedure to test whether the formation only depends on node characteristics or whether it involves strategic interaction. This test procedure does not require knowledge of model parameters. We show how a locally most powerful test statistic can be derived from the utility function. The network formation theory is extended from directed networks to undirected networks, in which a link is formed by bilateral agreement. The test procedure can also be used to test model parameters and to analyze restricted networks. Simulation results support the theory. The Second Chapter analyzes credit networks. Credit contracts among financial institutions form in a natural way a directed network. A default of a financial institution affects another institution via multiple paths in the network. The credit claims are settled in accordance with the seniority of the contract. The objective of this paper is to determine how the network and seniority structures impact the stability under shocks. In order to achieve this goal, we develop a simulation algorithm. The algorithm considers the network as well as the seniority constraints. We prove the correctness of the algorithm and derive a polynomial bound on the runtime. The simulation results indicate that the characteristics of a network have an impact on the overall stability of the financial system. Cyclic borrowing has a negative effect on stability. In a distressed situation, cyclic borrowing structure enhances.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis is a collection of three essays. The first two study how ideas spread through a network of individuals, and how it an advertiser can exploit it. In the model I develop, users choose their sources of information based on the perceived usefulness of their sources of information. This contrasts with previous literature where there is no choice made by network users and thus, the information flow is fixed. I provide a complete theoretical characterization of the solution and define a natural measure of influence based on choices of users. I also present an algorithm to solve the model in polynomial time on any network, regardless of the scale or the topology. I also discuss the properties of a network technology from a public economic standpoint. In essence, a network allows the reproduction of ideas for free for the advertiser. If there is any free-riding problem, I show that coalitions of users on the network can solve such problem. I also discuss the social value of networks, a value that cannot be captured for profit. The third essay is completely distinct from the network paradigm and instead studies funding rules for public universities. I show that a funding rule that depends solely on enrolment leads to "competition by franchise" and that such behavior is sometimes inefficient. I suggest instead an alternate funding rule that allows government to increase welfare without increasing spending in universities.

Book excerpt: Recent developments in the economics of networks have shown the potential fallacies of using one-sided logic in two-sided markets. In the third study I develop a two-sided market model to analyze the pricing and quality decisions of a profit maximizing managed care organization (MCO) in the presence of indirect network externalities between doctors and patients. The managed care organization faces trade-offs when choosing the quality of service, insurance premiums, and physician reimbursements. These trade-offs depend on patient health risk and physician cost distributions, the elasticity of supply of physicians with respect to reimbursements, the marginal cost of service quality, and the marginal utility derived by patients from access to a broader network of physicians and the quality of health services. In the case of iso-elastic distributions of patient health risk and physician cost of treatment, an increase in the cost of providing quality decreases the quality provided by the MCO, which leads to fewer policyholders, lower physician reimbursements, and fewer doctors in the preferred network. The insurance premium also decreases. An increase in the health risk of the population results in lower quality, lower reimbursements, and fewer physicians in the MCO's network. The insurance premium also decreases, but the decrease is smaller than the decrease in individuals' utility due to lower quality and fewer physicians, which leads to fewer policyholders.

Available in PDF, EPUB and Kindle. Book excerpt: While particularly dynamic and innovative, the digital and telecommunication industries are found to have a great tendency towards concentration, resulting in strong market power and raising concerns from competition and regulatory authorities. In this study focusing on such network industries, Jean-Marc Zogheib explores the interplay between public policy and firms' strategies by combining various tools of theoretical economic analysis adopted from industrial economics, network economics, and platform economics. Mr. Zogheib's thesis consists of three distinct essays: the first chapter examines how merger policy affects firms' entry strategies, the second chapter shifts the focus to public intervention by considering how the coexistence of private and public players affects competition and investment, while the third chapter investigates the role of privacy in competition between digital platforms and the importance of consumer data in the competitive analysis of mergers. This book clearly illustrates how economics can contribute essential building blocks to the construction of competitive reasoning and how the integration of competition law into economic models extended their collective utility. An important read for lawyers and economists alike. The book was awarded the inaugural Concurrences PhD Award in Economics.

Book excerpt: This dissertation is on economics of networks. The first two chapters study what network sellers and buyers create when there exist gains of trade. The last chapter studies information diffusion on a given network. In the first two chapters, I study sellers and buyers who trade via bargaining. Agents can often increase their bargaining power by increasing the value of their outside options. They may seek to invest in costly relationships with potential trade partners. That is, they form an endogenous trade network and then bargain with their trade partners. I study a two-stage model in which sellers and buyers trade non-cooperatively on an endogenous trade network. In Chapter 1, sellers are assumed to have no capacity constraints. The main result of this chapter is that even though agents can increase their bargaining power by forming relationships with multiple trading partners, there exists an efficient subgame perfect equilibrium--that is, all the gains from trade are realized with the minimum costs and without a delay. Chapter 2 assumes that sellers are endowed with one unit of a good for a trade following the tradition of the bargaining literature. The capacity constraint increases the seller's bargaining power if there are many buyers who want to buy a good from each seller. This may give incentives to sellers to invest in superfluous links. Chapter 2 shows that the market can achieve efficiency even if sellers have the capacity constraint. In specific, a bilateral trading network is supported as an equilibrium network. Chapter 3 studies information diffusion on a fixed network through word-of-mouth. Word-of-mouth is an effective tool that a firm leverages to advertise the quality of its products to uninformed consumers. Such viral marketing, however, may fail if the consumers' "words" are not credible. Suppose that consumers are located on a given network and a firm "buys" one consumer and employs her as an implant to make recommendations of a product to her neighbors regardless of the actual quality of the good. I show that the viral marketing fails if the consumer network has a node with an excessively high degree of connection--for instance, a star network or a complete network--which undermines the credibility of the recommendation from an implant employed by a firm to promote a bad quality product. Also, if the viral marketing works, a good quality product is spread out over the network while a bad quality is driven out.
