Social and Economic Networks in Cooperative Game Theory presents a coherent overview of theoretical literature that studies the influence and formation of networks in social and economic situations in which the relations between participants who are not included in a particular participant's network are not of consequence to this participant. The material is organized in two parts. In Part I the authors concentrate on the question how network structures affect economic outcomes. Part II of the book presents the formation of networks by agents who engage in a network-formation process to be able to realize the possible gains from cooperation.

It's not what you know, it's who you know. Or so the adage goes. Professor Matthew Jackson, world-leading researcher into social and economic networks, shows us why this is far truer than we'd like to believe. Based on his own ground-breaking research, The Human Network reveals how our relationships in school, university, work and society have extraordinary implications throughout our lives and demonstrates that by understanding and taking advantage of these networks, we can boost our happiness, success and influence. But there are also wider lessons to be learnt. Drawing on concepts from economics, mathematics, sociology, and anthropology, Jackson reveals how the science of networks gives us a bold new framework to understand human interaction writ large - from banking crashes and viral marketing to racism and the spread of disease. Filled with counter-intuitive ideas that will enliven any dinner party - e.g. how can our popularity in school affect us for the rest of our lives? - The Human Network is a "big ideas" book that no one can afford to miss.

Neuronale Netze sind Schlüsselelemente des Deep Learning und der Künstlichen Intelligenz, die heute zu Erstaunlichem in der Lage sind. Sie sind Grundlage vieler Anwendungen im Alltag wie beispielsweise Spracherkennung, Gesichtserkennung auf Fotos oder die Umwandlung von Sprache in Text. Dennoch verstehen nur wenige, wie neuronale Netze tatsächlich funktionieren. Dieses Buch nimmt Sie mit auf eine unterhaltsame Reise, die mit ganz einfachen Ideen beginnt und Ihnen Schritt für Schritt zeigt, wie neuronale Netze arbeiten: - Zunächst lernen Sie die mathematischen Konzepte kennen, die den neuronalen Netzen zugrunde liegen. Dafür brauchen Sie keine tieferen Mathematikkenntnisse, denn alle mathematischen Ideen werden behutsam und mit vielen Illustrationen und Beispielen erläutert. Eine Kurzeinführung in die Analysis unterstützt Sie dabei. - Dann geht es in die Praxis: Nach einer Einführung in die populäre und leicht zu lernende Programmiersprache Python bauen Sie allmählich Ihr eigenes neuronales Netz mit Python auf. Sie bringen ihm bei, handgeschriebene Zahlen zu erkennen, bis es eine Performance wie ein professionell entwickeltes Netz erreicht. - Im nächsten Schritt tunen Sie die Leistung Ihres neuronalen Netzes so weit, dass es eine Zahlenerkennung von 98 % erreicht – nur mit einfachen Ideen und simplem Code. Sie testen das Netz mit Ihrer eigenen Handschrift und werfen noch einen Blick in das mysteriöse Innere eines neuronalen Netzes. - Zum Schluss lassen Sie das neuronale Netz auf einem Raspberry Pi Zero laufen. Tariq Rashid erklärt diese schwierige Materie außergewöhnlich klar und verständlich, dadurch werden neuronale Netze für jeden Interessierten zugänglich und praktisch nachvollziehbar.

The Oxford Handbook of the Economics of Networks represents the frontier of research into how and why networks they form, how they influence behavior, how they help govern outcomes in an interactive world, and how they shape collective decision making, opinion formation, and diffusion dynamics. From a methodological perspective, the contributors to this volume devote attention to theory, field experiments, laboratory experiments, and econometrics. Theoretical work in network formation, games played on networks, repeated games, and the interaction between linking and behavior is synthesized. A number of chapters are devoted to studying social process mediated by networks. Topics here include opinion formation, diffusion of information and disease, and learning. There are also chapters devoted to financial contagion and systemic risk, motivated in part by the recent financial crises. Another section discusses communities, with applications including social trust, favor exchange, and social collateral; the importance of communities for migration patterns; and the role that networks and communities play in the labor market. A prominent role of networks, from an economic perspective, is that they mediate trade. Several chapters cover bilateral trade in networks, strategic intermediation, and the role of networks in international trade. Contributions discuss as well the role of networks for organizations. On the one hand, one chapter discusses the role of networks for the performance of organizations, while two other chapters discuss managing networks of consumers and pricing in the presence of network-based spillovers. Finally, the authors discuss the internet as a network with attention to the issue of net neutrality.

The sustained remarkable economic growth in the East Asian countries - Japan, South Korea, Taiwan, Hong Kong and Singapore - has brought about a great deal of debate over the role of the state in the market and society. Shin analyses the dynamic process of state interventions in the economy and social affairs in Korea from the early 1960s until the present with special reference to five policy areas: macro-economic policy, industrial policy, social security policy, labour policy, and education and training policy. Social and Economic Policies in Korea develops a unique explanation about the development of Korean social policy using the concepts of 'policy idea', 'policy network', and 'policy-linkages' to examine the causes, patterns and consequences of state interventions in the economy and social affairs over time. It should interest students and researchers of East Asian studies, social policy and development studies.

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.

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.

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.
