The paper studies a two-sector monetary economy with two factors of production, labor and capital. The industrial sector has increasing returns to scale, the consumption sector non-increasing returns. All firms maximize profits and markets clear. For each rate of return on capital the model...

An economy faces an unknown individual risk, such as the health effects of a recently discovered environmental hazard. Opinions may be widely different about the distribution of risks across the population. We study financial markets that suffice to reach efficient allocations in this situation....

We study paths which involve optimal use of a renewable resource under several alternative definitions of optimality, including the discounted utilitarian, Chichilnisky's, the Rawlsian and the green golden rule. Initially we consider an economy where the only good is the resource: subsequently,...

We 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. In this second respect, we are particularly interested in investigating the consequences...

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...

The present paper draws on recent findings of Chichilnisky and Wu [5] and Cass et al. [4], both of which study resource allocation with individual risks. Both of these papers develop further Malinvaud's [15,16] original formulation of general equilibrium with individual risks, and Arrow's [1]...

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...

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:...
