Few social scientific concepts have gathered so much attention and so many followers in such a short period of time as the concept of social capital. The purpose of this authoritative volume is to review the foundations for this fast growing field. The selected articles embed the concept in core theoretical work in economics, political science, sociology, development theory, and philosophy. Topics include: contemporary conceptual and philosophical foundations; forms of social capital; and the relation of social capital to both development and democracy. This collection will provide an insightful reference source to students and researchers alike.

In the latter part of the 20th century, humans are doing a particularly poor job of managing natural resources in a sustainable way over the long term.
Institutions, Ecosystems, and Sustainability focuses on long-term, sustainable natural resource management practices at the local, national, and international levels. The authors suggest that a major cause of the "sustainability problem" - regulatory policies for large areas that often threaten the sustainability of both natural resources and previously effective governance problems - lie in "scale" problems. Large scale ecosystems are not simply larger versions of smaller systems, and micro-scale ecosystems are not merely microcosms of large scale systems. The driving forces and feedback mechanisms operate at different levels and exhibit distinct patterns of their own.
Traditional management practices that do well at the local level cannot be expected to do equally well in handling activities organized at the continental or global scale. Even more importantly, when local systems are superseded by national or international management practices, local ecosystems frequently suffer.
The challenge is to match ecosystems and governance systems in ways that maximize the compatibility of these systems. This book builds upon this fundamental principle. Particularly valuable is the use of simulation exercises to explore the consequences of social institutions and a discussion of the progress being made in developing a broad global data base to test hypothesis about the relationship between ecosystems and social institutions, and to investigate ways to repair the damage already caused by scale mismatches.

Improving Irrigation in Asia is based on a longitudinal study over two decades on innovative intervention for sustained performance of irrigation systems. The work identifies key factors that can help explain the performance of interventions, and explicates lessons for resource management and the management of development assistance. In 1985, the Water and Energy Commission Secretariat of Nepal and the International Irrigation Management Institute developed an ingenious intervention program for nineteen irrigation systems located in the middle hills of Nepal in an attempt to overcome the prevailing 'best-practices' traps, in regard to assisting irrigation systems. This book highlights the innovativeness of the project lay in its provision of ample opportunities for farmers to make decisions regarding the operation of the irrigation system based on their local knowledge and creativity. The authors of this work, Elinor Ostrom, Wai Fung Lam, Prachanda Pradhan and Ganesh P. Shivakoti provide detailed analysis of these interventions and support the conclusion that farmers can build on an innovative intervention that not only provides physical improvements but also enhances farmers' problem-solving capacity. They argue that to achieve sustainable improvements in performance, the farmers themselves need to engage in collective action over time and support local entrepreneurs who provide leadership and stimulate adjustments to change. Providing practical policy solutions, this study will prove a fascinating and invaluable read for academics and scholars of development studies, resource management, and irrigation studies, as well as development specialists in international agencies, policy makers in governments and international donor agencies.

Elinor (Lin) Ostrom was awarded the 2009 Nobel Memorial Prize in Economic Sciences for her pathbreaking research on "economic governance, especially the commons," but she also made important contributions to several other fields of political economy and public policy. The range of topics she covered and the multiple methods she used might convey the mistaken impression that her body of work is disjointed and incoherent. This four-volume compendium of papers written by Lin, alone or with various coauthors (most notably including her husband and partner, Vincent), supplemented by others expanding on their work, brings together the common strands of research that serve to tie her impressive oeuvre together. That oeuvre, together with Vincent's own impressive body of work, has come to define a distinctive school of political-economic thought, the "Bloomington School." Each of the four volumes is organized around a central theme of Lin's work. The fourth and final volume, "Policy Applications and Extensions," collects sixteen papers that explore further applications and extensions of Ostrom's work. In fact, Ostrom had been writing about the scaling up of Bloomington School ideas to treat such problems since the mid-1990's. Her contributions to the climate change literature have been very impactful. An increasing number of scholars working on climate policy are now promoting various polycentric approaches to the problem. Equally influential, even seminal, was Ostrom's work (with Charlotte Hess) on the so-called "knowledge commons," a "hot" area of research dealing with contested issues such as the appropriate balance between private ownershipand open-access to information resources. The third part of the volume moves from applications of Ostrom's ideas to continuing her own efforts to improve the IAD and SES frameworks so as to make them even more useful for researchers and analysts. Finally, the volume concludes with two papers by Ostrom reflecting on continuing challenges confronting the social sciences generally and interdisciplinary research in particular. They are reminders that much work remains to be done.

The Quest to Understand Human Affairs presents fifty previously unpublished essays by Vincent Ostrom on the U.S. Government's environmental problems and resource governance and span the six decades of Ostrom's career in political science and public administration. Including everything from a 1947 essay on Western (U.S) issues in national politics to ending with a 2004 manuscript on Constitutional foundations and federal institutional forms, these essays examine significant developments in administration, constitutional design, and the evolution of theory and practice in the field of institutional analysis and development during the second half of the twentieth century and first decade of the new millennium. Political theorist, Barbara Allen, has edited the work and provided extensive notes that provide context and identify key events and persons cited in the works. These remarkable works not only offer specialists insight into developments in the fields of institutional analysis, resource governance, policy and administration, but also speak to general readers about worldwide transformations in democracies and human and environmental relations as well as the enduring challenge of sustaining just, productive political orders.

The governance of natural resources used by many individuals in common is an issue of increasing concern to policy analysts. Both state control and privatization of resources have been advocated, but neither the state nor the market have been uniformly successful in solving common pool resource problems. After critiquing the foundations of policy analysis as applied to natural resources, Elinor Ostrom here provides a unique body of empirical data to explore conditions under which common pool resource problems have been satisfactorily or unsatisfactorily solved. Dr Ostrom uses institutional analysis to explore different ways - both successful and unsuccessful - of governing the commons. In contrast to the proposition of the 'tragedy of the commons' argument, common pool problems sometimes are solved by voluntary organizations rather than by a coercive state. Among the cases considered are communal tenure in meadows and forests, irrigation communities and other water rights, and fisheries.

The questions and issues raised by Tocqueville in his monumental studies of France and America are just as crucial for understanding the evolution of democracy in the West and the development of democracy in the non-western world. They clearly show the breadth of Tocqueville's contributions to the development of modern social sciences. Among the questions addressed by Tocqueville were: How does the weight of the past affect the evolution of political institutions and political behavior? What impact do differences in physical environment have on the organization of society? What are the relationships between social equality, freedom, and democracy? To what extent does centralization destroy the capacity for local initiative and self-governance? What conditions are needed to nurture the flourishing of self-governing communities? What safeguards are needed to preserve freedom and to prevent incipient democracies from becoming dictatorships? Why has democracy had such a problem taking hold in many parts of the non-western world? How should one study democracy in non-western settings? Tocquevillian analytics can help us provide answers. Addressed to a wider audience than Tocqueville scholars, the book argues that Tocquevillian analytics can be used to understand developments in non-western as well as western societies and be updated to address such issues as globalization, ethnicity, New World-Old World comparisons, and East-West dynamics. The first part of the book examines the basic components of Tocquevillian analytics, outlining its stepwise, interdisciplinary approach to understanding societies and nations. The second part applies the Tocquevillian conceptual framework to the contemporary world and contains individual chapters on various regions of the world North America, Russia, Western Europe, Asia, Africa, and Latin America.

That oeuvre, together with Vincent's own impressive body of work, has come to define a distinctive school of political-economic thought, the "Bloomington School." Each of the four volumes is organized around a central theme of Lin's work. Volume 1 explores the roles played by the concept polycentricity in the disciplines of public administration, political science, and other forms of political economy. Polycentricity denotes a complex system of governance in which public authorities, citizens, and private organizations work together to establish and enforce the rules that guide their behavior. It encapsulates an approach toward policy analysis that blurs standard disciplinary boundaries between the social sciences. Throughout their long and remarkably productive careers, Elinor and Vincent Ostrom never tired of reminding us of the capacity of ordinary humans to transcend their own limitations by engaging with others in the myriad forms of collective action required to build and sustain a self-governing society. Their careers stand as exemplars of the proper relationship between rigorous scholarship and responsible citizenship.

The concepts of formal and informal remain central to the theory and practice of development more than half a century after they were introduced into the debate. They help structure the way that statistical services collect data on the economies of developing countries, the development of theoretical and empirical analysis, and, most important, the formulation and implementation of policy. This volume brings together a significant new collection of studies on formality and informality in developing countries. The volume is multidisciplinary in nature, with contributions from anthropologists, economists, sociologists, and political scientists. It contains contributions from among the very best analysts in development studies. Between them the chapters argue for moving beyond the formal-informal dichotomy. Useful as it has proven to be, a more nuanced approach is needed in light of conceptual and empirical advances, and in light of the policy failures brought about by a characterization of the 'informal' as 'disorganized'. The wealth of empirical information in these studies, and in the literature more widely, can be used to develop guiding principles for intervention that are based on ground level reality.

In addition to winning the 2009 Nobel Prize in Economic Sciences for her path-breaking research on "economic governance, especially the commons," Elinor (Lin) Ostrom also made important contributions to other fields of political economy and public policy. This four-volume compendium of papers written by Lin (often with coauthors, most notably her husband, Vincent), along with papers by others expanding on her work, brings together the strands of her entire empirical, analytical, theoretical, and methodological research program. Together with Vincent's important theoretical contributions, they defined a distinctive "Bloomington School" of political-economic thought. Volume 2 examines Lin's work on "the commons," in which she demonstrated that, in many cases, local resource users can solve collective-action problems through common-property management regimes. It comprises papers, including some that are not well known, related to and building on the findings of Governing the Commons (1990). Part I focuses on key attributes of biophysical resources and the institutions human communities have designed to govern them. Part II shows how in various social and ecological circumstances, different sets of institutions facilitate or impede the long-run sustainability of resources. Part III highlights Ostrom's first major research project on water resources in Southern California. It was a topic she (and her students) returned to with the specific intention of gathering data (more than 50 years' worth) for longitudinal analyses of combined institutional and ecological change. In sum, this volume contextualizes what is, at present, thought to be Lin's greatest legacy to social science: the conditions under which resources can be sustainably managed over very long periods of time by the collective action of ordinary people, beyond markets and states.

The analysis of how institutions are formed, how they operate and change, and how they influence behavior in society has become a major subject of inquiry in politics, sociology, and economics. A leader in applying game theory to the understanding of institutional analysis, Elinor Ostrom provides in this book a coherent method for undertaking the analysis of diverse economic, political, and social institutions.

"Understanding Institutional Diversity" explains the Institutional Analysis and Development (IAD) framework, which enables a scholar to choose the most relevant level of interaction for a particular question. This framework examines the arena within which interactions occur, the rules employed by participants to order relationships, the attributes of a biophysical world that structures and is structured by interactions, and the attributes of a community in which a particular arena is placed.

The book explains and illustrates how to use the IAD in the context of both field and experimental studies. Concentrating primarily on the rules aspect of the IAD framework, it provides empirical evidence about the diversity of rules, the calculation process used by participants in changing rules, and the design principles that characterize robust, self-organized resource governance institutions.

This book is about the institutions, incentives and constraints that guide the behaviour of people and organizations involved in the implementation of foreign aid programmes. While traditional performance studies tend to focus almost exclusively on the policies and institutions in recipient countries, this book looks at incentives in the entire chain of organizations involved in the delivery of foreign aid, from donor governments and agencies to consultants, experts and other intermediaries. Four aspects of foreign aid delivery are examined in detail: incentives inside donor agencies, the interaction of subcontractors with recipient organizations, incentives inside recipient country institutions, and biases in aid performance monitoring systems.

Local Commons and Global Interdependence explores the conditions for and possibilities of reaching such agreements. It develops a theoretical understanding of cooperation and discord at local and global levels, focussing on two of the key variables that affect outcomes: the number of actors and the degree of heterogeneity between them. This volume provides a broad-ranging introduction to the theory and theoretical issues involved, combining this with a detailed review of research evidence on how agreements to cooperate are established and maintained.

This book analyzes the institutions--incentives and constraints--that guide the behavior of persons involved in the implementation of aid programs. While traditional performance studies tend to focus almost exclusively on policies and institutions in recipient countries, the authors look at incentives in the entire chain of organizations involved in the delivery of foreign aid, from donor governments and agencies to consultants, experts and other intermediaries. They examine incentives inside donor agencies, the interaction of subcontractors with recipient organizations, incentives inside recipient country institutions, and biases in aid performance monitoring systems.

Advances in the social sciences have emerged through a variety of research methods: field-based research, laboratory and field experiments, and agent-based models. However, which research method or approach is best suited to a particular inquiry is frequently debated and discussed. "Working Together" examines how different methods have promoted various theoretical developments related to collective action and the commons, and demonstrates the importance of cross-fertilization involving multimethod research across traditional boundaries. The authors look at why cross-fertilization is difficult to achieve, and they show ways to overcome these challenges through collaboration.

The authors provide numerous examples of collaborative, multimethod research related to collective action and the commons. They examine the pros and cons of case studies, meta-analyses, large-N field research, experiments and modeling, and empirically grounded agent-based models, and they consider how these methods contribute to research on collective action for the management of natural resources. Using their findings, the authors outline a revised theory of collective action that includes three elements: individual decision making, microsituational conditions, and features of the broader social-ecological context.

Acknowledging the academic incentives that influence and constrain how research is conducted, "Working Together" reworks the theory of collective action and offers practical solutions for researchers and students across a spectrum of disciplines.

Traditional economic models of how to manage environmental problems relating to renewable natural resources, such as fisheries, have tended to recommend either government regulation or privatisation and the explicit definition of property rights. These traditional models ignore the practical reality of natural resource management. Many communities are able to spontaneously develop their own approaches to managing such common-pool resources. In the words of Mark Pennington: '[Professor Ostrom's] book Governing the Commons is a superb testament to the understanding that can be gained when economists observe in close-up detail how people craft arrangements to solve problems in ways often beyond the imagination of textbook theorists.' In particular, communities are often able to find stable and effective ways to define the boundaries of a common-pool resource, define the rules for its use and effectively enforce those rules. The effective management of a natural resource often requires 'polycentric' systems of governance where various entities have some role in the process. Government may play a role in some circumstances, perhaps by providing information to resource users or by assisting enforcement processes through court systems. Elinor Ostrom's work in this field, for which she won the Nobel Prize in economics in 2009, was grounded in the detailed empirical study of how communities managed common-pool resources in practice. It is essential that we avoid the 'panacea problem'. There is no correct way to manage common-pool resources that will always be effective. Different ways of managing resources will be appropriate in different contexts - for example within different cultures or where there are different physical characteristics of a natural resource. Nevertheless, there are principles that we can draw from the detailed study of the salient features of different cases to help us understand how different common-pool resources might be best managed; which rules systems and systems of organisation have the best chance of success or failure; and so on. Elinor Ostrom's approach has been praised by the left, who often see it as being opposed to free-market privatisation initiatives. In fact, her approach sits firmly within the classical liberal tradition of political economy. She observes communities freely choosing their own mechanisms to manage natural resource problems without government coercion or planning. In developing a viable approach to the management of the commons, it is important, among other things, that a resource can be clearly defined and that the rules governing the use of the resource are adapted to local conditions. This suggests that rules imposed from outside, such as by government agencies, are unlikely to be successful. There are important areas of natural resource management where Elinor Ostrom's ideas should be adopted to avoid environmental catastrophe. Perhaps the most obvious example relevant to the UK is in European Union fisheries policy. Here, there is one centralised model for the management of the resource that is applied right across the European Union, ignoring all the evidence about the failure of that approach.

What's wrong with foreign aid? Many policymakers, aid practitioners, and scholars have called into question its ability to increase economic growth, alleviate poverty, or promote social development. At the macro level, only tenuous links between development aid and improved living conditions have been found. At the micro level, only a few programs outlast donor support and even fewer appear to achieve lasting improvements. The authors of this book argue that much of aid's failure is related to the institutions that structure its delivery. These institutions govern the complex relationships between the main actors in the aid delivery system and often generate a series of perverse incentives that promote inefficient and unsustainable outcomes. In their analysis, the authors apply the theoretical insights of the new institutional economics to several settings. First, they investigate the institutions of Sida, the Swedish aid agency, to analyze how that aid agency's institutions can produce incentives inimical to desired outcomes, contrary to the desires of its own staff. Second, the authors use cases from India, a country with low aid dependence, and Zambia, a country with high aid dependence, to explore how institutions on the ground in recipient countries also mediate the effectiveness of aid. Throughout the book, the authors offer suggestions about how to improve aid's effectiveness. These suggestions include how to structure evaluations in order to improve outcomes, how to employ agency staff to gain from their on-the-ground experience, and how to engage stakeholders as "owners" in the design, resource mobilization, learning, and evaluation processes of development assistance programs.

This volume brings a set of key works by Elinor Ostrom, co-recipient of the Nobel Prize in Economic Sciences, together with those of Vincent Ostrom, one of the originators of Public Choice political economy. The two scholars introduce and expound their approaches and analytical perspectives on the study of institutions and governance. The book puts together works representing the main analytical and conceptual vehicles articulated by the Ostroms to create the Bloomington School of public choice and institutional theory. Their endeavours sought to 're-establish the priority of theory over data collection and analysis', and to better integrate theory and practice. These efforts are illustrated via selected texts, organised around three themes: the political economy and public choice roots of their work in creating a distinct branch of political economy; the evolutionary nature of their work that led them to go beyond mainstream public choice, thereby enriching the public choice tradition itself; and, finally, the foundational and epistemological dimensions and implications of their work.
