Available in PDF, EPUB and Kindle. Book excerpt: Network effects, the increase in value of consuming a product if many other consumers use the same product, is a feature of many markets of high-technology products. Frequently cited examples of products exhibiting network effects are telecommunication or software products. This paper surveys the burgeoning empirical literature that has developed especially during the last years. After theoretical work dominated the earlier years of research in this area, newer research has combined theoretical models with empirical studies and applied work with direct implications for marketing and public policy. Furthermore, insights from the study of social networks have been applied to analyse how consumers interact with each other. The paper argues that a closer analysis of the network structure of consumer interaction promises fruitful future research avenues and advances in our understanding of how network effects operate.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation includes three chapters on estimating structural economics models. My research focuses on empirically study consumers' utility from different products, the impact of network effects on consumers' demand for products, and multi-network firms' dynamic pricing strategies. The three chapters share the same feature of estimating a discrete choice demand model, but differ in the static versus dynamic setting and the underlying economics question and strategic behaviors that I'm interested.Chapter 1"The Operating System Network Effect and Telecom Carriers' Dynamic Pricing of Smartphones."The utility a consumer realizes from owning a smartphone increases with its operating system (OS) network size. Due to this OS network effect, multi-network telecom carriers have a different pricing strategy for smartphones than the single- network manufacturers in a dynamic environment. While manufacturers choose higher prices for larger networks, carriers, who can internalize competition across OSs, have incentives to choose lower prices for larger networks. The carriers' pricing strategy contributes to the increasing smartphone users and OS concentration. In this paper, I first analyze a theoretical model to compare the pricing strategies of the carriers and manufacturers. Then I design a structural model of consumers' demand and the carriers' dynamic pricing game for smartphones, and empirically study the impact of the OS network effect and carriers' two-year contract policy on the smartphone market penetration and OS concentration. I estimate the model using product level data from August 2011 to July 2013 in the US. I deal with the empirical challenges of dynamic prices for multi-product carriers, high dimension continuous state variables, and asymmetric oligopolistic firms in the estimation. The results show that the OS network size has a positive and significant impact on consumer utility. I then study two counterfactual cases in which I eliminate the OS network effect and the carriers' pricing strategy, respectively. I find that, without the OS network effect, the smartphone penetration rate would decrease by 54.7% and the largest OS share difference decrease by 31.7% by May 2013. Without the carriers' pricing strategy, the penetration rate would decrease by 29.1% and the OS market share difference decrease by 11.2%.Chapter 2"The Operating System Network Effect and Consumers' Dynamic Demand of Smartphones with Two-Year Contracts."This paper studies consumers' dynamic demand of smartphones on two-year wireless contracts. Individuals' demand decisions are affected by the improving quality and changing prices of smartphones, and the OS network effect, and their current smartphone contract status. Consumers need to pay high early termination fees if they end active contracts. The dynamic demand model in this paper incorporates the evolving choice set, prices, endogenous OS network sizes, and the termination policies in the smartphone industry. The preliminary results find that the OS network effect is large and significant. In addition, compared with dynamic model results, a static demand model tends to underestimate the OS network effect and overestimate price coefficient.Chapter 3"Store Brands and Retail Grocery Competition in Breakfast Cereals."This paper empirically analyzes the impacts of store brands on grocery retailers and consumers in the market for breakfast cereals. On the supply side, store brands help a retailer to avoid direct competition with other retailers and change the set of retailer's products. On the demand side, introducing store brands changes the national brands prices and consumers' choice set. We analyze the effects via demand estimation for a single grocery store chain Dominick's at Chicago in 1997 and counterfactual exercises. The estimation results show that consumers' unobserved utility of buying at a competing retailer is higher for consumers that value national brands, and is lower for ones that value Dominick's store brands. This is consistent with the claim that store brands help a retailer to avoid competition. The counterfactual calculations show that the profit loss from removing store brands is higher if the retailer has more competitors, with a median loss of 4.33% of profits from cereals. Existence of store brands increases national brands prices and consumer welfare increases slightly when store brands are removed.

Available in PDF, EPUB and Kindle. Book excerpt: Indirect network effects are of prime interest to marketers because they affect the growth and takeoff of software availability for, and hardware sales of, a new product. While prior work on indirect network effects in the economics and marketing literature is valuable, these literatures show two main shortcomings. First, empirical analysis of indirect network effects is rare. Second, in contrast to the importance the prior literature credits to the chicken-and-egg paradox in these markets, the temporal pattern - which leads which? - of indirect network effects remains unstudied. Based on empirical evidence of nine markets, this study shows, among others, that: (1) indirect network effects, as commonly operationalized by prior literature, are weaker than expected from prior literature; (2) in most markets we examined, hardware sales leads software availability, while the reverse almost never happens, contradicting existing beliefs. These findings are supported by multiple methods, such as takeoff and time series analyses, and fit with the histories of the markets we studied. The findings have important implications for academia, public policy and management practice. To academia, it identifies a need for new, and more relevant, conceptualizations of indirect network effects. To public policy, it questions the need for intervention in network markets. To management practice, it downplays the importance of the availability of a large library of software for hardware technology to be successful.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three essays that address recent topics in corporate finance that concern for scholars, policymakers, and investors. Main body of this dissertation has been developed based on the "nexus of contracts" theory of the firm which in recent years has sparked renewed debates on the motivation underlying firm size and boundary. The first essay explores a network of interconnected firms and examines the impact of the firm's relationships with peers, rivals, and customers on its capital structure, and how the firm's revealed peers influence its financing decisions. We demonstrate that industry classification approach is fraught with measurement error, and instead implement an alternative peer identification scheme that designates peer groups as those explicitly disclosed by managers to shareholders. The results contrast with previous studies that find only weak evidence for peer effects on capital structure. We find that peer effects are particularly strong when focal firms have persistent rivals, in the sense of supplying common customers for at least two consecutive years. While constructing the firm's actual network poses a challenge, the new approach can lead to more real-world insights about firm behavior. In the second essay, I approach to a challenging version of peer effects model with firm's and peer's multinomial decision outcome as endogenous and financial fundamentals as exogenous explanatory variables. I show that managers do not set dividend policy independently and they are significantly under the influence of few self-disclosed diverse competitors rather than industry peers. The test results show that firm's dividend change actions are significantly correlated with past dividend actions of its peers and it is highly predictable for the next period. I also investigate and report marginal effects of firm's and peers' different endogenous and exogenous determinants on the outcome decision variable for example a peer group with an overall dividend increase action in the past 180 days, increases the chance of the dividend increase in the focal firm. Considering the market capitalization of dividend paying firms, the identified marginal effects and prediction of the cash distribution are economically meaningful and important. In the third essay, I propose a new approach to model and measure intangible value of the firm as the joint of network feature and book value of the firm. Despite the growing importance, the empirical asset pricing research has struggled to evaluate the effects of intangible assets on firms' market value. Utilizing characteristics of the firm network, I propose a network-centric value factor to replace the under-performing traditional value factor (HML) in a series of asset pricing factor model. I show that the new value factor portfolio provides stronger performance in all periods of the sample. I also explore short and long strategies to better understand effects of the networks on value of the firms. Initial findings emphasize that asset pricing studies should adjust the factor models by including intangible network value of the firm.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis contributes to the understanding of peer effects, both methodologically and empirically. The endogeneity of network formation has been a major obstacle to the study of peer influence. The first and the second chapters of the thesis propose a causal identification solution in the potential outcome framework. Combining results from multiple causal inference and statistical network analysis, I show that confounding can be addressed by inferring propensity scores of network link formation from the adjacency matrix. This identification strategy imposes minimum restrictions on the data-generating process and, unlike existing econometric solutions, does not rely on any parametric modelling. As an application, I estimate the effect of high school friendships on bachelor's degree attainment. While previous literature finds that exposure to more high-achieving boys makes girls less likely to obtain a bachelor's degree, I show that if the girls consider the boys as friends, their interactions induce a positive impact instead. Since friendship endogeneity has been addressed, the estimated effect is causal. The third chapter looks at the peer effects generated by group competition. It focuses on the gender differences in preference for competition in a setting where the competition does not involve face-to-face confrontation, and effort is the only determinant of the final ranking. I first develop a model of group competition with heterogeneous preference for ranking. With empirical implications generated from the theoretical model, I then test the gender difference in the preference parameter using web-scraped data from Duolingo, a free online foreign-language learning platform with over 300 million users. Every week, language learners on Duolingo are randomly allocated to groups of 30 people to compete on the number of language lessons completed during that week. The empirical results suggest in this setting, females have a stronger preference for ranking than males.

Book excerpt: Network externalities spur the growth of networks and the adoption of network goods in two ways. First, they make it more attractive to join a network the larger its installed base. Second, they create incentives for network members to actively recruit new members. Despite indications that the latter "peer effect" can be more important for network growth than the installed-base effect, it has so far been largely ignored in the literature. We address this gap. Using a game-theoretical model, we show that under conservative assumptions the increase in network size due to the peer effect is by an additive constant which, for small networks, can amount to a large relative increase. The difference between small, local, personal networks and large, global, anonymous networks thus arises endogenously from our model. We use survey data from users of the Internet services, Skype and eBay, to illustrate and support our theoretical results. As predicted by the model, we find that the peer effect matters strongly for the network of Skype users which effectively consists of numerous small sub-networks but not for that of eBay users. Since many network goods give rise to small, local networks, our findings bear relevance to the economics of network goods and related social networks in general.
