Several empirical papers have indicated that the health inequalities in the Nordic welfare states seem to be at least as high as health inequalities in other European countries even if the Nordic states have a more egalitarian income structure. This is in contrast to standard economic theory...

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 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 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...

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 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...

This paper combines the theory of optimal extraction of exhaustible resources with the theory of greenhouse externalities, to analyse problems of global warming when the supply side is considered. The optimal carbon tax will initially rise but eventually fall when the externality is positively...

In this paper, we present an economic model of moral motivation. Consumers prefer regarding themselves as socially responsible individuals. Voluntary contributions to public goods are motivated by this preference. The self-image as socially responsible is determined by a comparison of one's...

This paper addresses the frequently articulated worry for the unemployment impacts of abating CO2 emissions. The Spanish economy is ridden by unemployment rates well above the EU average. At the same time the deviation from EU's intermediate emission goals is more serious than for most other EU...

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...
