Book excerpt: In this dissertation, we study three link formation problems in mobile and economic networks: (i) company matching for mergers and acquisitions (M&A) network in the high-technology (high-tech) industry, (ii) mobile application (app) matching for cross promotion network in mobile app markets, and (iii) online friendship formation in mobile social networks. Each problem can be modeled as link formation problem in a graph, where nodes represent independent entities (e.g., companies, apps, users) and edges represent interactions (e.g., transactions, promotions, friendships) among the nodes. First, we propose a new data-analytic approach to measure firms' dyadic business proximity to analyze M&A network in the high-tech industry. Specifically, our method analyzes the unstructured texts that describe firms' businesses using latent Dirichlet allocation (LDA) topic modeling, and constructs a novel business proximity measure based on the output. Using CrunchBase data including 24,382 high-tech companies and 1,689 M&A transactions, we empirically validate our business proximity measure in the context of industry intelligence and show the measure's effectiveness in an application of M&A network analysis. Based on the research, we build a cloud-based information system to facilitate competitive intelligence on the high-tech industry. Second, we analyze mobile app matching for cross promotion network in mobile app markets. Cross promotion (CP) is a new app promotion framework, in which a mobile app is promoted to the users of another app. Using IGAWorks data covering 1,011 CP campaigns, 325 apps, and 301,183 users, we evaluate the effectiveness of CP campaigns in comparison with existing ad channels such as mobile display ads. While CP campaigns, on average, are still suboptimal as compared with display ads, we find evidence that a careful matching of mobile apps can significantly improve the effectiveness of CP campaigns. Our empirical results show that app similarity, measured by LDA from apps' text descriptions, is a significant factor that increases the user engagement in CP campaigns. With this observation, we propose an app matching mechanism for the CP network to improve the ad effectiveness. Third, we study friendship network formation in a location-based social network. We build a structural model of social link creation that incorporates individual characteristics and pairwise user similarities. Specifically, we define four user proximity measures from biography, geography, mobility, and short messages (i.e., tweets). To construct proximity from unstructured text information, we build LDA topic models of user biography texts and tweets. Using Gowalla data with 385,306 users, three million locations, and 35 million check-in records, we empirically estimate the structural model to find evidence on the homophily effect in network formation.

This book was released on 2016-05-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting recent research on the international integration of infrastructures in Europe, this book combines general and methodological chapters and examples from different a variety of sectors such as transport, electricity and communication networks. Particular focus is on the contrast between the 'Europe of nation states' of the nineteenth century (up to 1914) and the emerging 'integrated Europe' after World War II. Additional contributions provide perspectives from beyond Europe. The wide range of topics gives a good overview of the different challenges posed and the strategies employed in each sector to establish internationally compatible networks, procedures and standards. This work strengthens comparative research as a complement to the detailed analysis of singular cases that often characterises previous works in this field. Methodologically, it therefore contributes to the progress of tools and strategies for comparative historical research. Part of the emerging research area dealing with the mechanisms of international collaboration, this book brings together recent research from European integration history, policy studies, political economy and cultural studies. Considering the growing intensity of international collaboration and exchange in many parts of social and economic life, it is also of topical interest.

Available in PDF, EPUB and Kindle. Book excerpt: Networks pervade social and economic life, and they play a prominent role in explaining a huge variety of social and economic phenomena. Standard economic theory did not give much credit to the role of networks until the early 1990s, but since then the study of the theory of networks has blossomed. At the heart of this research is the idea that the pattern of connections between individual rational agents shapes their actions and determines their rewards. The importance of connections has in turn motivated the study of the very processes by which networks are formed. In Connections, Sanjeev Goyal puts contemporary thinking about networks and economic activity into context. He develops a general framework within which this body of research can be located. In the first part of the book he demonstrates that location in a network has significant effects on individual rewards and that, given this, it is natural that individuals will seek to form connections to move the network in their favor. This idea motivates the second part of the book, which develops a general theory of network formation founded on individual incentives. Goyal assesses the robustness of current research findings and identifies the substantive open questions. Written in a style that combines simple examples with formal models and complete mathematical proofs, Connections is a concise and self-contained treatment of the economic theory of networks, one that should become the natural source of reference for graduate students in economics and related disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: Networks of relationships help determine the careers that people choose, the jobs they obtain, the products they buy, and how they vote. The many aspects of our lives that are governed by social networks make it critical to understand how they impact behavior, which network structures are likely to emerge in a society, and why we organize ourselves as we do. In Social and Economic Networks, Matthew Jackson offers a comprehensive introduction to social and economic networks, drawing on the latest findings in economics, sociology, computer science, physics, and mathematics. He provides empirical background on networks and the regularities that they exhibit, and discusses random graph-based models and strategic models of network formation. He helps readers to understand behavior in networked societies, with a detailed analysis of learning and diffusion in networks, decision making by individuals who are influenced by their social neighbors, game theory and markets on networks, and a host of related subjects. Jackson also describes the varied statistical and modeling techniques used to analyze social networks. Each chapter includes exercises to aid students in their analysis of how networks function. This book is an indispensable resource for students and researchers in economics, mathematics, physics, sociology, and business.

Available in PDF, EPUB and Kindle. Book excerpt: In a world where networks become a dominant form of organization, the structure of networks and the position of individuals in these networks affect individual behavior and aggregate economic outcomes. The analysis of network formation by a central planner or by individuals themselves is at the heart of this thesis on the economics of networks.Chapter 1 theoretically studies the optimal formation and protection of networks by a central planner knowing that an external agent can destroy k links. The protection of the network can be guaranteed either by densifying the links between nodes, or by protecting the links. When the cost of protection is relatively small, a minimally connected network composed of protected links guarantees the communication flow; if this cost is high, the optimal solution is to form a symmetric network where each node has at least k+1 non-protected links.Chapter 2 explores the decentralized formation of networks in the laboratory by analyzing individual linking formation decisions when one agent has a higher value than others and that the linking formation process is sequential. The results show that sequentiality facilitatesthe coordination on efficient networks but that do not correspond to the Subgame PerfectEquilibrium. The heterogeneity across agents increases the asymmetry of networks because of the polarization of links on the agent with a higher value.Chapter 3 studies the impact of the endogenous formation of networks on the importance of peer effects, applied to dishonest behavior. In order to identify the effects of social comparisons, two controlled environments are designed in the laboratory in which individuals choose or not their peers, and then observe their behavior. The results show that peer effects on dishonest behavior are significantly higher when individuals can choose their peers.

Available in PDF, EPUB and Kindle. Book excerpt: Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.

Book excerpt: Social relations are crucial for understanding diverse economic actions and a network perspective is central to that explanation. Simple exchanges involving money, labor, and commodities combine into complexly connected systems. Economic networks span many levels of analysis, from persons (consumers, employees), to groups (households, workteams), organizations (corporations, interest groups), populations (industries, markets) and the rapidly expanding global economic system. David Knoke blends network theories from a range of disciplines and empirical studies of domestic and international economies to illuminate how economic activity is embedded in and constrained by social ties among economic actors. Social capital, in the form of connections to others holding valuable resources, is vital for finding a job, buying a car, creating a new industry, or triggering a global financial crisis. In nontechnical terms the author explicates the core network concepts, measures, and analysis methods behind these phenomena. The book also includes many striking network diagrams to provide visual insights into complex structural patterns. This accessible book offers an invaluable critique for both undergraduate and graduate students in economic sociology and social network analysis courses who seek a better understanding of the multifaceted economic webs in which we are all entangled.

Available in PDF, EPUB and Kindle. Book excerpt: Half of all workers are hired through personal referrals, and networks of social connections channel the flows of capital, technology, and international trade. Sociologists and economists alike recognize that economic exchange is shaped by social networks, which propagate information and facilitate trust, but each discipline brings a distinct theoretical perspective to the study of networks. Sociologists have focused on how networks shape individual behavior, economists on how individual choices shape networks. The Missing Links is a bold effort by an interdisciplinary group of scholars to synthesize sociological and economic theories of how economic networks emerge and evolve. Interweaving sophisticated theoretical models and concrete case studies, The Missing Links is both an introduction to the study of economic networks and a catalyst for further research. Economists Rachel Kranton and Deborah Minehart illustrate their field's approach to modeling network formation, showing how manufacturers form networks of suppliers in ways that maximize profits. Exemplifying the sociological approach, Ronald Burt analyzes patterns of cooperation and peer evaluations among colleagues at a financial organization. He finds that dense connections of shared acquaintances lead to more stable reputations. In the latter half of the book, contributors combine the insights of sociology and economics to explore a series of case studies. Ray Reagans, Ezra Zuckerman, and Bill McEvily investigate an R & D firm in which employees participate in overlapping collaborative teams, allowing the authors to disentangle the effects of network structure and individual human capital on team performance. Kaivan Munshi and Mark Rosenzweig examine how economic development and rising inequality in India are reshaping caste-based networks of mutual insurance and job referrals. Their study shows that people's economic decisions today are shaped both by the legacy of the caste hierarchies and by the particular incentives and constraints that each individual faces in an evolving labor market. Economic globalization is forging new connections between people in distant corners of the world, while unsettling long-standing social relations. Anyone interested in understanding the opportunities and challenges of this era of rapid change will find a highly informative guide in The Missing Links.

Book excerpt: The widespread availability of mobile devices along with recent advancements in networking capabilities make opportunistic mobile social networks (MSNs) one of the most promising technologies for next-generation mobile applications. Opportunistic Mobile Social Networks supplies a new perspective of these networks that can help you enhance spontaneous interaction and communication among users that opportunistically encounter each other, without additional infrastructure support. The book explores recent developments in the theoretical, algorithmic, and application-based aspects of opportunistic MSNs. It presents the motivation behind opportunistic MSNs, describes their underpinning and key concepts, and also explores ongoing research. Supplies a systematic study of the constrained information flow problem Reviews the recent literature on social influence in complex social networks Presents a complete overview of the fundamental characteristics of link-level connectivity in opportunistic networks Explains how mobility and dynamic network structure impact the processing capacity of opportunistic MSNs for cloud applications Provides a comprehensive overview of the routing schemes proposed in opportunistic MSNs Taking an in-depth look at multicast protocols, the book explains how to provide pervasive data access to mobile users without the support of cellular or Internet infrastructures. Considering privacy and security issues, it surveys a collection of cutting-edge approaches for minimizing privacy leakage during opportunistic user profile exchange. The book concludes by introducing a framework for mobile peer rating using a multi-dimensional metric scheme based on encounter and location testing. It also explains how to develop a network emulation test bed for validating the efficient operation of opportunistic network applications and protocols in scenarios that involve both node mobility and wireless communication.

All of them came to Stockholm primarily because they recognize the growing im portance of networks as complex systems, and their home institutions do not offer any systematic lectures on this topic. The Networks Course was originally initiated jointly by the Summer University of Southern Stockholm Foundation and the County Council of Stockholm, the Swedish Aviation Administration, the Swedish National Road Administration, the Swedish Post, the Swedish State Railways, and Telia AB. They have all served as joint sponsors and hosts for the Course. In the year 1993 the Course also was sponsored by the Swedish Transport and Communications Research Board. All these organizations have supported the publication of a series of key lectures from the Course, to be released as a single volume entitled Networks in Action. It is the ambition of the Foundation to create continuity in its activities for the future. The board has proposed to its principals to take a decision in this direction. It is my expectation that this will be the case for the Networks Course from 1995. This book will then serve as a basic reference for use in an era when the topic of Communication-Networks will be included on a permanent basis in the Summer University's agenda.

Book excerpt: We use a laboratory experiment to explore dynamic network formation in a six-player game where link creation requires mutual consent. The analysis of network outcomes suggests that the process tends to converge to the pairwise-stable (PWS) equilibrium when it exists and not to converge at all when it does not. When multiple PWS equilibria exist, subjects tend to coordinate on the high-payoff one. The analysis at the single choice level indicates that the percentage of myopically rational behavior is generally high. Deviations are more prevalent when actions are reversible, when marginal payoff losses are smaller and when deviations involve excessive links that can be removed unilaterally later on. There is, however, some heterogeneity across subjects.
