Environmental problems like global climate change and stratospheric ozone depletion can only be remedied if states cooperate with one another. But sovereign states usually care only about their own interests. So states must somehow restructure the incentives to make cooperation pay. This is what treaties are meant to do.
A few treaties, such as the Montreal Protocol on Substances that Deplete the Ozone Layer, succeed. Most, however, fail to alter the state behavior appreciably. This book develops theory that explains both the successes and the failures. In particular, the book explains when treaties are needed, why some work better than others, and how treaty design can be improved. The best treaties strategically manipulate the incentives states have to exploit the environment, and the theory developed in this book shows how treaties can do this.
The theory integrates a number of disciplines, including economics, political science, international law, negotiation analysis, and game theory. It also offers a coherent and consistent approach. The essential assumption is that treaties be self-enforcing that is, individually rational, collectively rational and fair.
The book applies the theory to a number of environmental problems. It provides information on more than three-hundred treaties, and analyses a number of case studies in detail. These include depletion of the ozone layer, whaling, pollution of the Rhine, acid rain, over-fishing, pollution of the oceans, and global climate change.
The essential lesson of the book is that treaties should not just tell countries what to do. Treaties must make it in the interests of countries to behave differently. That is, they mustrestructure the underlying game. Most importantly, they must create incentives for states to participate in a treaty and for parties to comply.

Climate change, nuclear proliferation, and the threat of a global pandemic have the potential to impact each of our lives. Preventing these threats poses a serious global challenge, but ignoring them could have disastrous consequences. How do we engineer institutions to change incentives so that these global public goods are provided?
Scott Barrett provides a thought provoking and accessible introduction to the issues surrounding the provision of global public goods. Using a variety of examples to illustrate past successes and failures, he shows how international cooperation, institutional design, and the clever use of incentives can work together to ensure the effective delivery of global public goods.

This book honours Partha Dasgupta, and the field he helped establish; environment and development economics. It concerns the relationship between social systems (to include families, local communities, national economies, and the world as a whole) and natural systems (critical ecosystems, forests, water resources, mineral deposits, pollution, fisheries, and the Earth's climate). Above all, it concerns the poverty-environment nexus: the complex pathways by which people become or remain poor, and resources become or remain overexploited. With contributions by some of the world's leading economists, including five recipients of the Nobel Prize in Economics, in addition to scholars based in developing countries, this volume offers a unique perspective on the environmental issues that matter most to developing countries.
