Global fisheries are increasingly overfished. The existing international regulatory structure, a set of regional fisheries management organizations (RFMOs), has failed to prevent overfishing. Regulatory problems exist because of the common pool resource character of fisheries and the fishing...

In this article, I develop and evaluate a model of dynamic climate governance. The model is based on the premise that global warming is such a complex problem that present political realities do not allow an immediate solution to it. I propose that current mitigation activities should focus on...

The United Nations has declared 2008 to be the International Year of Planet Earth. It is being organised under the auspices of the International Union of Geological Sciences and UNESCO. Planning for the International Year of Planet Earth has consisted of establishing 10 major science themes...

Environmental degradation is increasingly causing cross-border displacement of people, but countries have formed no treaties to facilitate collaboration on the issue. When is such collaboration feasible, and how should environmental displacement treaties be designed? We present a game-theoretic...

This article proposes an analytical framework for exploring policy responses to common challenges of environmental governance. Observing that governance involves multiple processes, I begin by identifying a conceptual platform for studying unilateral learning and adaptation as well as...

If major emitters fail to mitigate global warming, they may have to resort to geoengineering techniques that deflect sunlight from planet Earth and remove carbon dioxide from the atmosphere. In this article, I develop a strategic theory of geoengineering. I emphasize two key features of...

While neoliberal institutionalists argue that treaties facilitate collective action, many North-South regulatory treaties focus on largely national problems in developing countries. As such, these treaties present a puzzle: why a global treaty to address national regulatory problems? We argue...

The renaissance in the theoretical analysis of intergovernmental organizations (IGOs) has focused on formal IGOs (FIGOs), but many IGOs are subject to no formal treaty and/or have no permanent secretariat. Important examples of informal IGOs (IIGOs) include the G-groups that are the locus of...
