In the presence of rising carbon concentrations more attention should be given to the role of the oceans as a sink for atmospheric carbon. We do so by setting up a simple dynamic global carbon cycle model with two reservoirs containing atmosphere and two ocean layers. The net flux between these...

The relationships among the Hamiltonian, NNP, and the level of sustainable consumption/utility have been widely misunderstood. This paper dispels the misconceptions and provides further new insight into these relationships. We show generally that for autonomous dynamic optimizing economies, a...

We translate Hotelling's continuous-time, exhaustible resource extraction Model of 1931 into a linear program of present value extraction cost minimization subject to a stock endowment and period by period demand constraints. The appropriate form of the demand constraints allows for resource...

In a Ramsey policy regime, heterogeneity in beliefs about the potential costs of climate change is shown to produce policy ambiguities that alter carbon prices and taxation. Three sources of ambiguity are considered: (i) the private sector is skeptical, with beliefs that are unknown to the...

The paper aims at extending the debate on Environmental Kuznets Curves to the case of non-renewable resources and to discuss the driving forces that might give rise to EKC's in this case. The paper at hand deviates from the standard EKC analysis in two ways: First, mostly EKC's are analyzed for...

We borrow standard assumptions from the non-renewable-resource-taxation and from the directed-technical-change literatures, to take a full account of the incentives to perform R&D activities in a dirty-resource sector and in a clean-resource-substitute sector. We show that a gradual rise in the...

Using a dynamic framework with strategic interactions, we study the management of a non-renewable natural resource when property rights are generally weak. Under generally weak property rights both the resource stock and the revenues from exploiting it are imperfectly protected, due to...

The paper analyzes resource policies in an economy in which renewable and fossil resources are realistically assumed to be essential inputs to production. Also realistically, the two types of resources are imperfect substitutes whose degree of substitutability can, however, increase over time....

We study backstop adoption and carbon dioxide emission paths in a two-region model with unilateral climate policy and non-renewable resource consumption. The regions have an equal endowment of the internationally tradable resource and a backstop technology. We first study the case of a...
