We model dynamic mechanisms for a global commons. Countries benefit from both consumption and aggregate conservation of an open access resource. A country's relative value of consumption-to-conservation is privately observed and evolves stochastically. An optimal quota maximizes world welfare...

This paper formulates a dynamic model of global carbon consumption in the absence of an effective international agreement. Each period, countries extract carbon from the global ecosystem. A country's output depends both on its carbon usage and on the ecosystem ("stored carbon"). The desired mix...

It is tricky to design local regulations on global externalities, especially so if firms are mobile. We show that when costs and outside options are firms’ private information, the threat of firm relocation leads to local regulations that are stricter, not looser. This result is general and...

This study represents the first attempt at an integrated approach to assessing the potential impacts of climate change on the national economy of South Africa via a number of (but not necessarily all) impact channels. The study focuses on outcomes by about 2050. The results show the multiple...

Global sea-levels are rising due to global warming. Major impacts on the world’s coasts are sand beach erosion, salination of ground water, and inundation. Adaptation is the only option to address these future threats as the mitigation of CO2 emissions is not capable of preventing sea-level...

Until now, most of the growing climate legal litigations mainly concern environmental associations or victims against energy of energy-users firms or States. However, in a near future, because of exacerbating sudden floods linked to climate change, future litigations could (will) concern...

The costs of coastal sector impacts from sea level rise (SLR) are an important component of the total projected economic damages of climate change, a major input to decision-making and design of climate policy. Moreover, the ultimate costs to coastal resources will depend strongly on adaptation,...
