Book Description
We study informal insurance within communities, explicitly recognizing the possibility that subgroups of individuals may destabilize insurance arrangements among the larger group. We therefore consider self-enforcing risk-sharing agreements that are robust not only to single-person deviations but also to potential deviations by subgroups. However, such deviations must be credible, in the sense that the subgroup must pass exactly the same test that we apply to the entire group; it must itself employ some self-enforcing risk-sharing agreement. We observe that the stability of subgroups is inimical to the stability of the group as a whole. Two surprising consequences of this analysis are that stable groups have (uniformly) bounded size, a result in sharp contrast to the individual-deviation problem, and that the degree of risk-sharing in a community is generally non-monotonic in the level of uncertainty or need for insurance in the community.

Book Description
Volume 3 of this series of the Handbooks in Economics follows on from the previous two volumes by focusing on the fundamental concepts of agricultural economics. The first part of the volume examines the developments in human resources and technology mastery. The second part follows on by considering the processes and impact of invention and innovation in this field. The effects of market forces are examined in the third part, and the volume concludes by analysing the economics of our changing natural resources, including the past effects of climate change.Overall this volume forms a comprehensive and accessible survey of the field of agricultural economics and is recommended reading for anyone with an interest, either academic or professional, in this area. *Part of the renown Handbooks in Economics series*Contributors are leaders of their areas*International in scope and comprehensive in coverage

Book Description
This highly topical volume, with contributions from leading experts in the field, explores a variety of questions about membership based organizations of the poor. Analyzing their success and failure and the internal and external factors that play a part, it uses studies from both developed and developing countries. Put together by a group of prestigious editors, the contributors address a range of questions, including: What structures and activities characterize MBOPs? What is meant by success and what factors account for success? What are the internal (governance structure and leadership) and external (policy environment) factors that account for success? Are these factors replicable across countries or even within countries? What are the constraints to successful MBOPs expanding, or to new ones being formed? What sort of policy environment enables the success of MBOPs and the formation of successful MBOPs? What types of institutional reforms are needed to ensure the representation of the poor through their own MBOs? This is an insightful work, that will be invaluable for students and researchers studying or working in the areas of international and development economics and development studies.

Book Description
All men and women are subject to risk: illness, accident, death. Some shocks affect their ability to feed and support themselves properly, either temporarily: unemployment, crop failure, and loss of property; or permanently: disability, and skill obsolescence.This report summarises what is known and also what is not known about the sources of risk faced by the rural poor and their coping strategies. It examines the impact of risk and risk-coping strategies on development and the way in which governments and international organisations can assist in dealing with risk and overcoming poverty.

Book Description
Broad and diverse ranges of activities are conducted within and by organized groups of individuals, including political, economic and social activities. These activities have become a subject of intense interest in economics and game theory. Some of the topics investigated in this collection are models of networks of power and privilege, trade networks, co-authorship networks, buyer–seller networks with differentiated products, and networks of medical innovation and the adaptation of new information. Other topics are social norms on punctuality, clubs and the provision of club goods and public goods, research and development and collusive alliances among corporations, and international alliances and trading agreements. While relatively recent, the literature on game theoretic studies of group formation in economics is already vast. This volume provides an introduction to this important literature on game-theoretic treatments of situations with networks, clubs, and coalitions, including some applications.

Book Description
Poor people in developing countries are often affected by droughts, floods, illness, crop failure, job loss, and economic downturns. Much of their energy goes into coping with these shocks and into day-to-day survival. While insurance and credit markets, combined with widespread social security, provide an important cushion against poverty in rich countries, the need for immediate survival may lock the poor into persistent poverty in developing countries.The poor in developing countries do have informal mechanisms to cope with risk and misfortune. These are based on income diversification, risk avoidance, self-insurance by saving together with family, and community-based mutual assistance. Nevertheless, the scope of these mechanisms remains limited. Repeated individual-specific shocks such as illness or pests, or covariate risks associated with drought, flood, or recession, undermine the ability of individuals and their families to cope withrisk.We now know much more about vulnerability to risk and how poor people cope. Even more importantly, we have learned much about the large long-term consequences of these risks, which condemns many to persistent poverty and excludes them from economic growth. But there is much that can be done. The micro-level studies that underpin this book offer new insights on how effective public action could be more effective in protecting the vulnerable against persistent poverty. Policy should focus onproviding a comprehensive menu of ex-ante and post-crisis protection mechanisms, including new forms of insurance, savings, safety nets, and the means to strengthen the poor's asset base. Local communities have a big role to play: public funds should not be used to replace indigenous community-basedsupport networks; rather they should be used to build on the strengths of these networks to ensure broader and more effective protection.With numerous thematic chapters and case studies of both best practice and of failure, from a mix of low-income and middle-income countries across the developing world, this book evaluates alternatives in widening insurance and protection provision, and makes an important contribution to the topical field of insurance and risk.

Book Description
Empirical analysis of two decades of pioneering pension and social security reform in Latin America and the Caribbean shows that much has been achieved, but that critical challenges remain. In tackling this unfinished agenda, a great deal can be learned from the reform experience of countries in the region. 'Keeping the Promise,' produced by the chief economist's office for the Latin America and Caribbean region at the World Bank, evaluates policy reforms in 12 countries, points to successes and shortcomings, and proposes priorities and options for future reform.
