This book is the first to bring an economics perspective in a rigorous manner to complex decision-making in the management of supply chains. It provides the foundations for the modeling of the interrelationships among decision-makers in supply chains, ranging from manufacturers, distributors, and retailers, to the consumers, assuming individualized behavior. The models handle both competition and cooperation and provide the resulting product flows and prices in the chains. A unique network economics perspective is brought to the issue, setting the book apart from the numerous management and operations research volumes available. After an introduction of the theoretical foundations, the book extends and applies the theory to energy supply chains in the form of electric power generation and distribution networks. The relationships between electric power supply chains and transportation networks are vividly captured through theoretical results and the solution of practical examples. The book then explores environmental supply chain and financial networks with intermediation, which are interpreted as supply chains and also solved as such. Throughout, the underlying theme is that of transportation networks and how the relationships between supply chain networks and the more established theory of transportation network equilibria can be applied and exploited for logistic-type applications. Economists and transportation researchers will find the book's theory and applications of great interest. Operations researchers and management scientists as well as practitioners in business logistics will be interested in the book's methodological and practical tools.

Networks provide the foundation for the functioning of our societies and economies. Their study has had a long tradition in such fields as engineering, operations research, management science and computer science. More recently, the disciplines of finance and economics have come to be rich and fascinating sources of network-based problems and applications. This focused and refereed volume of contributions from leading international scholars provides a wealth of innovations in the study of financial and economic networks. The volume presents entirely new results: the conceptualization of the stock market as a graph, the evolution of financial systems as networks, the incorporation of electronic transactions in international finance (from a network perspective), new formalisms for the study of supply chains (as fluid models and in an network economic framework) and new applications of agent-based computational economics trade networks with intermediaries and worker-employer networks. Finally, trade networks in web-based caching are introduced. Financial applications covered include: portfolio optimization with transaction costs, integrated pension and corporate planning, evolutionary financial networks, international finance and electronic transactions as well as hedging instruments for transportation networks. Innovative approaches to economic networks are developed in the context of supply chain and distribution networks, a variety of trade (including web-based caching) networks and even worker-employer networks.A major addition to this exciting and important subject, Innovations in Financial and Economic Networks will be an invaluable resource for economists and the networks community, as well as researchers and students in computational economics and finance, operations research, management science, applied mathematics and computer science.

Transportation networks are essential to the functioning of societies and economies and provide the infrastructure for the movement of people and goods over space and time. The existence and utilization of transportation networks are fundamental to the modern age and the negative effects of congestion and pollution associated with their increasing usage demand urgent attention.This book cogently addresses the question as to whether transportation networks are sustainable: that is, can they last, given the growing demands on the network, on the one hand, and the desire to alleviate the associated negative impacts, on the other. Anna Nagurney answers the question positively by providing a rigorous foundation for the formulation, analysis, and computation of solutions to such problems through the use of appropriate policies ranging from tolls and tradable pollution permits to the design of the networks themselves.Sustainable Transportation Networks will be of great value to students, researchers, and practitioners of transportation studies, environmental economics, regional science, and urban planning.

The advent of the Information Age has transformed the ways in which individuals work, travel, and conduct their daily activity. Anna Nagurney and June Dong lay out the theory of supernetworks, networks that exist over and above existing electronic networks, in order to formalize decision-making in the Information Age. Supernetworks are conceptual in scope, graphical in perspective, and, with the accompanying theory, predictive in nature. In this book, the authors provide a unifying framework for the study of decision-making by a variety of economic agents including consumers and producers as well as distinct intermediaries in the context of today's networked economy. They provide the conceptual, analytical, and computational tools for the study of supernetworks. Their approach is rigorous and of sufficient generality and detail to give added insight into the behavior and structure of large-scale, interacting and competitive network systems, such as transportation, telecommunication, and financial networks. Areas studied include: supply chain networks with electronic commerce, financial networks with intermediation, telecommunicating versus commuting decision-making, teleshopping versus shopping decision-making, as well as transportation and location decisions. Case studies drawn from practice are provided for illustration purposes. Academics and practitioners in economics, business, and operations research along with management scientists, transportation and logistics researchers, computer scientists and applied mathematicians will find this book fascinating and useful.

A unified treatment of the vulnerabilities that exist in real-world network systems—with tools to identify synergies for mergers and acquisitions Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain World presents a comprehensive study of network systems and the roles these systems play in our everyday lives. This book successfully conceptualizes, defines, and constructs mathematically rigorous, computer-based tools for the assessment of network performance and efficiency, along with robustness and vulnerability analysis. The result is a thorough exploration that promotes an understanding of the critical infrastructure of today's network systems, from congested urban transportation networks and supply chain networks under disruption to financial networks and the Internet. The authors approach the analyses by abstracting not only topological structures of networks, but also the behavior of network users, the demand for resources, the resulting flows, and the associated costs. Following an introduction to the fundamental methodologies and tools required for network analysis and network vulnerability, the book is organized into three self-contained parts: Part I—Network Fundamentals, Efficiency Measurement, and Vulnerability Analysis explores the theoretical and practical foundations for a new network efficiency measure in order to assess the importance of network components in various network systems. Methodologies for distinct decision-making behaviors are outlined, along with the tools for qualitative analysis, the algorithms for the computation of solutions, and a thorough discussion of the unified network efficient measure and network robustness with the unified measure. Part II—Applications and Extensions examines the efficiency changes and the associated cost increments after network components are eliminated or partially damaged. A discussion of the recently established connections between transportation networks and different critical networks is provided, which demonstrates how the new network measures and robustness indices can be applied to different supply chain, financial, and dynamic networks, including the Internet and electronic power networks. Part III—Mergers and Acquisitions, Network Integration, and Synergies reveals the connections between transportation networks and different network systems and quantifies the synergies associated with the network systems, from total cost reduction to environmental impact assessment. In the case of mergers and acquisitions, the focus is on supply chain networks. The authors outline a system-optimization perspective for supply chain networks and also formalize coalition formation using game theory with insights into the merger paradox. With its numerous network examples and real-world applications, Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain World is an excellent book for courses in network science, transportation science, operations management, and financial networks at the upper-undergraduate and graduate levels. It is also a valuable reference for researchers and practitioners in the areas of applied mathematics, computer science, operations research, management science, finance, and economics, as well as industrial, systems, and civil engineering.

This original book presents a new basis for environmental policymaking: environmental networks. This framework graphically simplifies the analysis of environmental problems and emphasizes the spatial nature of economic activity and pollution dispersion.The book first discusses the foundations of environmental economics before going on to apply the environmental network approach to different firm structures. The authors then extend the analysis to incorporate multiple products and pollutants, the presence of transaction costs, the availability of investment in production technologies, and the issue of noncompliance versus compliance. They also apply the network approach to pollution caused by transportation and assess the success of permits in limiting this. The authors then formulate integrated models, analyzing the use of permits and taxes in firms, producers, and consumers, as well as transportation and trade routes. This book will be of interest to students, researchers, practitioners, and policymakers in environmental and transport economics.
