This paper reviews a range of issues relating to tradeable carbon dioxide quotas. It considers the economic principles on which they are based, compares them with alternative carbon abatement policies, and reviews many aspects of how tradeable quotas would be implemented in practice ...<BR><P>Cette...</p>

We review the optimal pattern of carbon emission abatements across countries in a simple multi-country world. We model explicitly the fact that the atmosphere is a public good. Within this framework we establish conditions for it to be necessary for optimality that the marginal cost of abatement...

We consider the economics of global environmental risks. In this area, we are dealing with risks that are poorly understood, endogenous, collective, and irreversible. In policy terms, the nature and extent of uncertainty about global climate change implies that society's position will be...

We study a growth model with an environmental asset which is a source of utility and an input to consumption and production. The stock of this asset follows its own ecological dynamics, which are affected by economic activity. We study the implications of an approach to ranking sequences of...
