A single condition, limited arbitrage, is shown to be necessary and sufficient for the existence of a competitive equilibrium and the core in economies with any number of markets, finite or infinite, with or without short sales. This extends earlier results of Chichilnisky [8] for finite...

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...

Ws use growth models with natural resources to study the con- sequences 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...

The paper studies a two-region economy , with two sectors and three factors of production : oil, capital and labor . The South exports oil in exchange for industrial goods from the North . There is a net capital inflow to the South . This equals the difference between its export revenues and...

We consider here optimal use patterns for renewable resources and address the problem of optimal use of renewable resources under a variety of assumptions both about the nature of the economy in which these resources are embedded and about the objective of that economy. Although we focus here on...

We provide a simple construction of social choice rules for economies with infinite populations. The rules are continuous, Pareto and non-dictatorial; they are constructed as limits of individual preferences when the limit exists, and otherwise as adequate generalizations. This contrasts with...

We consider an economy which imports energy from a monopolistic price-setter. The domestic general equilibrium of this economy adjusts in response to the price of energy. We define the total cross price elasticity of demand between energy and capital as the cross price elasticity across general...
