We present an intertemporal equilibrium model for fossil fuels, and study the effects on oil prices, extraction paths and oil wealth of an international carbon tax on fossil fuel consumption Our conclusion is that a carbon tax will hurt OPEC more than other producers, as the cartel is induced by...

Popular instruments to regulate consumption of oil in the transport sector include fuel taxes, biofuel requirements, and fuel efficiency. Their impacts on oil consumption and price vary. One important factor is the market setting. We show that if market power is present in the oil market, the...

This paper addresses the impact of endogenous technology through research and development (Ramp;D) and learning by doing (LbD) on the timing of environmental policy. We develop two models, the first with Ramp;D and the second with LbD. We study the interaction between environmental taxes and...

We study the optimal time path for clean energy innovation policy. In a model with emission reduction through clean energy deployment, and with R&D increasing the overall productivity of clean energy, we describe optimal R&D policies jointly with emission pricing policies. We find that while...
