This collection of articles aims at revitalizing the study of kinship and exchange in a social network perspective. It brings together studies of empirical systems of marriage and descent with investigations of the flow of material resources in societies of Africa, Asia, the Pacific and Europe. Restudies of classic ethnographic cases and fieldwork studies of kinship and exchange demonstrate how the social and material aspects of society are related, and address issues of concern to anthropology and the neighbouring disciplines of history, sociology and economics. This book marks the emergence of an era in the study of kinship and exchange using a productive combination of ethnographic substance with formal methods, one which leaves behind older structural-functionalist and culturalist assumptions.
Throughout the local Bronze and Iron Age, European and Mediterranean societies appear to have been involved in complex systems of exchange networks which invariably affected local customs and historical developments. Archaeological evidence suggests social and economic phenomena, cultural expressions and technological skills stemmed from multifaceted encounters between local traditions and external influences. Examples of cultural openness and transcultural hybridisation seem to be more of a norm than an exception. The articles in the volume explore the dynamic relationship between regionally contextualized transformations and inter-regional exchange networks. Particular effort has been put in approaching the issue in a multidisciplinary perspective. Continental Europe and the Mediterranean may be characterized by specific development and patterns of relations, but the authors draw attention to how those worlds were not alien to each other and illustrate how common interpretative tools can be successfully applied and a comprehensive approach including both zones adopted.
This book focuses on forecasting foreign exchange rates via artificial neural networks (ANNs), creating and applying the highly useful computational techniques of Artificial Neural Networks (ANNs) to foreign-exchange rate forecasting. The result is an up-to-date review of the most recent research developments in forecasting foreign exchange rates coupled with a highly useful methodological approach to predicting rate changes in foreign currency exchanges.
Networks and Markets argues that economists' knowledge of markets and sociologists' rich understanding of networks can and should be combined. Together they can help us achieve a more coherent view of economic life, where transactions follow both the logic of economic incentives and the established channels of personal relationships. Market exchange is impersonal, episodic, and carried out at arm's length. All that matters is how much the seller is asking, and how much the buyer is offering. An economic network, by contrast, is based upon more personalized and enduring relationships between people tied together by more than just price. Networks and Markets focuses on how the two concepts relate to each other: Are social networks an essential precondition for successful markets, or do networks arise naturally out of markets, as faceless traders build reputations and gain confidence in each other? The book includes contributions by both sociologists and economists, applying the concepts of markets and networks to concrete empirical phenomena. Among the topics analyzed, the book explains how, in Taiwan, South Korea, and Japan, firms combine into tightly-knit business blocs, how wholesalers in a Marseille fish market earn the loyalty of customers, and how ethnic retailers in the U.S. share valuable market information with other shopkeepers from their ethnic group. A response to each chapter discusses the issue from the standpoint of the other discipline. Sociologists are challenged to go beyond small-scale economic exchange and to integrate their concept of networks into a broader understanding of the economic system as a whole, while economists are challenged to consider the economic implications of network ties, which can be strong or weak, unconditional or highly contingent. This book proves that both economics and sociology provide stronger insights when they study markets and networks as parallel forms of exchange. But it also clarifies the healthy division of labor that remains between the two disciplines. Sociologists are adept at showing how markets are framed by social institutions; economists specialize in explaining how markets perform, taking the social context as a given. Networks and Markets showcases what each discipline does best and reveals where each discipline would do better by borrowing from the other.
The field of network exchange has grown over the last 20 years from a few scattered studies to substantial publications in leading journals. Today network exchange is as advanced as any area of sociology. Willer and his contributors present its most advanced theory, Network Exchange Theory, and, by assembling and supplementing formulations now spread across leading journals, provide scholars with a unique collection. Contributors examine basic issues in theory as well as research. The end product is a well-tested theory which relates social structure to social action under a wide range of conditions, and is proven to be a useful tool for structural analysis at both the micro and macro levels. An important text and guide for researchers and students of social theory, structure, and social psychology.
In Stateless Commerce, Barak Richman uses the colorful case study of the diamond industry to explore how ethnic trading networks operate and why they persist in the twenty-first century. How, for example, does the 47th Street diamond district in midtown Manhattan—surrounded by skyscrapers and sophisticated financial institutions—continue to thrive as an ethnic marketplace that operates like a traditional bazaar? Conventional models of economic and technological progress suggest that such primitive commercial networks would be displaced by new trading paradigms, yet in the heart of New York City the old world persists. Richman’s explanation is deceptively simple. Far from being an anachronism, 47th Street’s ethnic enclave is an adaptive response to the unique pressures of the diamond industry. Ethnic trading networks survive because they better fulfill many functions usually performed by state institutions. While the modern world rests heavily on lawyers, courts, and state coercion, ethnic merchants regularly sell goods and services by relying solely on familiarity, trust, and community enforcement—what economists call “relational exchange.” These commercial networks insulate themselves from the outside world because the outside world cannot provide those assurances. Extending the framework of transactional cost and organizational economics, Stateless Commerce draws on rare insider interviews to explain why personal exchange succeeds, even as most global trade succumbs to the forces of modernization, and what it reveals about the limitations of the modern state in governing the economy.
The use of modern planning and optimization systems for process synchronization in value networks requires the optimal information exchange between the entities involved. The central focus of Sven Grolik's study is the development of efficient mechanisms for the coordination of information allocation by the example of interconnected transportation marketplaces. Unlike traditional information allocation algorithms, the algorithms developed in his analysis are based on update mechanisms which maintain a weak consistency of replicated information in the network. Sven Grolik shows that these algorithms enable savings concerning the update costs as well as increase the performance within the network, but at the same time guarantee compliance with quality of service levels concerning the currency of information. The focus of this work is the development of decentralized, online algorithms which make a logically distributed computation possible on the basis of local information. The development of these innovative algorithms is based on approaches of multi-agent system theory as well as distributed simulated annealing techniques.
For this volume, archaeologist Jane W. Pires-Ferreira analyzed artifacts from the Valley of Oaxaca in order to understand more about prehistoric trade patterns in the region. Using her analyses, she was able to describe obsidian exchange networks, iron ore mirror exchange networks, and shell exchange networks in Early and Middle Formative Mesoamerica.
How is it possible to identify the circulation of materials or of finished objects in Neolithic Europe, as well as the social networks involved? Several approaches exist for the researcher, and the present volume provides some examples.
This title examines the structure, scale and complexity of economic systems in the pre-Hispanic Americas, with a focus on the central highlands of Mexico, the Maya Lowlands and the central Andes.
