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

We use growth models with natural resources to study the consequences of a ranking of intertemporal paths, due to Chichilnisky, which places weight on their very long run or limiting characteristics as well as on their characteristics over any finite period. This criterion shows more...

We present a restriction on the domain of individual preferences that is both necessary and sufficient of the existence of it social choice rule that is continuous, anonymous, and respects unanimity. The restriction is that the space of preferences be contractible. Contractibility admits it...

We consider contracts to purchase assets by means of streams of payments over time, with the asset as security. These give the purchaser an option not present if all payment is made up front, the option of stopping payments and delivering the asset in satisfaction of the remaining debt. We argue...

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...

OUR CONCERN in this paper is to analyze the optimal long-run pricing policies of oil-exporting countries. These might be described briefly as the policies which best meet their objectives, subject to the various limitations imposed on them by the realities of world economic forces. The...
