Welfare analyses of energy taxes typically show that systems with uniform rates perform better than differentiated systems, especially if revenue increases can be recycled via cuts in more distortionary taxes. However, in the practical policy debates, the scope for efficiency gains is traded...

Welfare analysis of energy taxes typically shows that systems with uniform rates perform better than differentiated systems. However, most western countries include some exemptions for their energy-intensive export industry, and hence, avoid this potential welfare gain. Böhringer and Rutherford...

The market power of firms in intermediate good markets is found to generate a substantial welfare cost. Markup pricing of intermediate good firms contributes to increase the wedge between the marginal product of labor and the wage rate received by workers, as intermediate good firms add...

The European competition rules restrict governments' opportunity to differentiate terms of energy accessibility among firms and industries. This easily runs counter with regional and industrial goals of national energy policies. Norway levies a tax on use of electricity, but exempts main...

We analyze how knowledge spillovers influence the optimal timing of R&D policy. Using numerical simulations we find that optimal subsidies to R&D may be rising over time even when the returns to knowledge is decreasing. The optimal time profile of the subsidies is determined by the elasticity of...

This study tests whether the strong double dividend hypothesis holds within a setting where a uniform tax on green house gas emissions is raised above the international quota price within the Norwegian economy. The hypothesis does not hold within a framework where detailed technology choices...

This study finds that the welfare gain, excluding environmental effects, generated by increasing the Norwegian tax rate on purchase of electric cars from 8 to 37 percent amounts to approximately 5500- 6500 NOK (or 680-820 euro) per ton increase in GHG emissions in the long run. Substantial tax...

This study investigates whether biofuel policies or favourable taxation of electric cars should be employed to satisfy a green house gas emission target connected to private transport within the Norwegian economy. The study shows that implementation of biofuel generates a welfare gain in the...
