During the second half of the 1970s there was massive government interference in wage and price formation in Norway. Incomes policies changed in the first half of the 1980s - the hey days of "dynamic tax policies" in Norway - and during the second half of the 1980s new direct interventions in...

There is a large number of regional agreements concerning Greenhouse Gas (GHG) emissions, often linked to other regional integration agreements. The most successful one in making effort in reducing carbon emissions is the Emission Trading System by the European Union (EU ETS). Apart from this...

In this paper we seek to identify different driving forces behind the fall in LNG liquefaction unit costs. Our focus is on organizational learning including process specific R&D, but we also seek to account for autonomous technological change, scale effects and the effects of upstream...

This paper studies the timing of subsidies for environmental research and development (R&D) and how innovation policy is influenced by the costs of emissions. We use a dynamic computable general equilibrium (CGE) model with both general R&D and specific environmental R&D. We find two results...

In the longer run, effects on R&D and the implementation of advanced abatement technology may be at least as important as short-run cost effectiveness when we evaluate public environmental policy. In this paper, we show that the number of firms that adopt advanced abatement technology could be...

This paper shows that tradable emissions permits and an emissions tax have a risk-related technology choice effect. We first examine the first- and second-order moments in the probability distributions of optimal abatement and production under the two instruments. The two instruments will, in...

This paper shows that tradable emissions permits and an emissions tax affect the firms' technology choice differently under uncertainty. A tax encourages the most flexible technology if and only if stochastic costs and the equilibrium permit price have sufficiently strong positive covariance,...

This paper provides new evidence on the role of non-market based ("command-and-control") regulations in relation to innovations in environmental technologies. While pricing is generally considered the first-best policy instrument, non-market regulations, such as technology standards and...

The theoretical justification for a greenhouse gas (GHG) cap and trade system is that participants will trade emission permits until their marginal costs of abatement equal the equilibrium price of emission permits. Abatement is then globally cost efficient. We demonstrate, however, that when...

This paper examines the impacts of R&D tax credits and direct R&D subsidies on Norwegian firms' patenting, with a particular focus on environmental patenting. Whereas direct subsidies are aimed at projects with low private and high social return, tax credits do not discriminate between projects...
