In this paper we ask whether OPEC still gains from cartelisation in the oil market despite low producer prices and a modest market share. We apply two intertemporal equilibrium models of the global oil market; one consisting of a cartel and a fringe, and one describing a hypothetical competitive...

In this paper we focus on how an international climate treaty will influence the exploration of oil in Non-OPEC countries. We present a numerical intertemporal global equilibrium model for the fossil fuel markets. The international oil market is modelled with a cartel (OPEC) and a competitive...

This paper studies the effects on fossil fuel prices, extraction paths and petroleum wealth of an international carbon tax on fossil fuel consumption. We present an intertemporal equilibrium model for fossil fuels, where the main focus is on the oil market. The impacts of a global carbon tax of...

This paper studies the impacts on Western European CO2 emissions of a reduction in Norwegian gas sales. The impacts are due to changes in energy demand and energy supply, but environmental and political regulations also play an important role. The gas supply model DYNOPOLY is used to analyse the...

Abatement can be performed by measures that have an impact on present emissions, but no lasting effect, and by long-lived infrastructure investments. We study the optimal combination of short and long-lived options for reducing greenhouse gas (GHG) emissions, by specifying abatement cost...

This article discusses how different climate policy instruments such as CO2 taxes and renewable energy subsidies affect the profitability of fossil fuel production, given that a fixed global climate target shall be achieved in the long term. Within an intertemporal framework, the model analyses...

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

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...

We study the interactions between fuel efficiency improvements in the transport sector and the oil market, where the efficiency improvements are policy-induced in certain regions of the world We are especially interested in feedback mechanisms of fuel efficiency such as the rebound effect,...
