Climate effects of unilateral carbon policies are undermined by carbon leakage. To counteract leakage and increase global cost-effectiveness carbon tariffs can be imposed on the emissions embodied in imports from non-regulating regions. We present a theoretical analysis on the economic...

In the absence of effective world-wide cooperation to curb global warming, import tariffs on embodied carbon have been proposed as a potential supplement to unilateral emissions pricing. We consider alternative designs for such tariffs, and analyze their effects on global welfare within a...

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...

We analyse welfare effects of supporting general versus emission saving technological development when carbon emissions are regulated by a carbon tax. We use a computable general equilibrium model with induced technological change (ITC). ITC is driven by two separate, economically motivated...

Research and development (R&D) play a pivotal role for innovation and productivity growth, and knowledge spillovers can make the case for public support to private R&D. In small and open economies, absorption of foreign knowledge through exports and imports can be even more decisive for economic...

This paper analyses the effects of so-called "green" tax reforms on a small, open economy producing an imperfect substitute for foreign goods, using an intertemporal general equilibrium model. The labour market is characterised by union wage setting, and a fixed exchange rate implies wage...

Indirect taxes such as value added taxes (VAT) generate a substantial part of tax revenue in many countries. This paper analyses welfare effects of different reforms in the Norwegian system of indirect taxation. The main reform studied is the introduction of a uniform VAT rate on all goods and...

This paper analyses the non-environmental welfare costs of an environmental tax reform using a numerical intertemporal general equilibrium model for the Norwegian economy. The tax reform is revenue neutral such that an increase in the carbon tax rate is accompanied by a reduction in the payroll...

The working of the labour market is important for the total welfare effects of tax reforms. This paper analyses, by using a computable general equilibrium model for the Norwegian economy, how different assumptions about labour mobility between industries and wage formation influence the...
