China is appraised to have the world's largest exploitable reserves of shale gas, although several legal, regulatory, environmental and investment-related issues will likely restrain its scope. China's capacity to successfully face these hurdles and produce commercial shale gas will have a...

During recent years increased attention has been given to second-generation wood-based bioenergy. The carbon stored in the forest is highest when there is little or no harvest from the forest. Increasing the harvest from a forest, in order to produce more bioenergy, may thus conflict with the...

Non-renewable and renewable resources are imperfect substitutes due to technical and geographical constraints. What is the role of imperfect substitution on the optimal transition path to the clean technologies? We address this question by characterizing the optimal growth path and resource use...

Recent contributions have questioned whether biofuels policies actually lead to emissions reductions, and thus lower climate costs. In this paper we make two contributions to the literature. First, we study the market effects of a renewable fuel standard. Opposed to most previous studies we...

We study the effects on the food price of introducing biofuels as a substitute for fossil fuel in the energy market. Energy is supplied by a price-leading oil cartel and a competitive fringe of farmers producing biofuel. Biofuel production shares a finite land resource with food production. A...

Demand for oil is very price inelastic.  Facing such demand, an extractive cartell induces the highest price that does not destroy its demand, unlike the conventional Hotelling analysis: the cartel tolerates ordinary substitutes to its oil but deters high-potential ones.  Limit-pricing...

This paper provides a coopetitive model for a global green economy taking into account the environmental sustainability. In particular we propose a differentiable coopetitive game G (in the sense recently introduced by D. Carfì) to represent a basic green economy interaction among a country c...

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...

Optimal climate policy is studied. Coal, the abundant resource, contributes more CO2 per unit of energy than the exhaustible resource, oil. We characterize the optimal sequencing oil and coal and departures from the Herfindahl rule. “Preference reversal” can take place. If coal is very dirty...
