Equal treatment for the present and the future was required in two axioms for sustainable development introduced by the author. This article shows that the two axioms are equivalent to awareness of physical limits in the long run future. We prove that two optimization problems are equivalent :...

The paper proposes two axioms that capture the idea of sustainable development and derives the welfare criterion that they imply. The axioms require that neither the present nor the future should play a dictatorial role. Theorem 1 shows there exist sustainable preferences, which satisfy these...

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...

Economics often provides the wrong incentives to those who control the assets, such as people in developing countries where most forests are located and who could potentially benefit most from conservation . There is increasing unease about this situation, and an emerging view is that standard...

This paper examines the role of the international market in mediating North-South relations and analyzes how the market works in distributing the gains from trade. It is argued that the international market does not always provide an adequate engine of growth for the South if that region...

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 labor productivity in agriculture within a two-region, two factor and two commodity economy. Increases in productivity can lead to higher or to lower agricultural prices, depending on the internal structure of the economy. We give necessary and sufficient conditions for either outcome;...

The first two sections of the paper are devoted to a combination of Kuznets and structuralist stories, where we ask how the agricultural/nonagricultural terms of trade and income distribution must adjust to permit both savings and investment and commodity market balance to be assured. It will be...
