We show that (i) subsidies for renewable energy policies with the intention of encouraging substitution away from fossil fuels may accentuate climate change damages by hastening fossil fuel extraction, and that (ii) the opposite result holds under some specified conditions. We focus on the case...

This paper explains how, in the context of incomplete coordination among all countries, unilateral policies that might at first sight seem pro-green could actually turn out to harm the global environment. The free-riding motives and the difficulty of reaching an effective international...

We examine the profitability of cross-ownership in an oligopolistic industry where firms compete as Cournot rivals. We consider a symmetric cross-ownership structure in which a subset of k firms engage in cross-shareholding and each firm has an equal silent financial interest in the other firms,...

This paper develops sufficient conditions under which the Weak Green Paradox may (and may not) hold in terms of subsidies for biofuel production such that the supply-side responses by fossil fuel producers may more than offset the substitution to biofuels. Analytical results are derived and...

This paper studies the intertemporal substitutions between the use of renewable and non renewable resources if the productivities of the different kinds of resources are improved through time by exogenous trends of dedicated technical progress. We show that the optimal exploitation paths of the...

There is a large literature on the optimal order of exploitation of natural resources. We explore the impact of specific technical progress that enables the saving of resource inputs in production on the order of exploitation. Models of growth tend to assume uniform and global technical progess....

We study the optimal policies of research and development in the context of a resource-exploiting economy. We distinguish two cases: non-renewable resources and renewable resources. In the first case, we show that it is useful to construct an index of scarcity, which is the product of the level...

Oil companies often announce revised estimates of their reserves. This indicates that stock uncertainty is a prevalent feature of natural resource industries. In this paper we consider the multi-deposit case where resource extraction produces information about the size of reserves. We show that...
