We present a model for an energy market that includes a green certificate for suppliers of energy from renewables and a purchaser commitment to buy these certificates. We show that price and volume effects in the energy market are ambigous under a wide range of alternative levels of the...

We use a two-period model to investigate intertemporal effects of cost reductions in climate change mitigation technologies for the power sector. With imperfect climate policies, cost reductions related to carbon capture and storage (CCS) may be more desirable than comparable cost reductions...

The paper derives a general equilibrium demand function for electricity by imposing a specific closure rule on a large CGE-model of the Norwegian economy. By a decomposition technique it quantifies the contribution from various mechanisms to the price sensitivity of aggregate electricity demand....

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...

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...

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...

The analysis of the effect of tariffs for labor productivity faces the challenge of tariff policy endogeneity. Tariff policy is designed to promote economic development and the industrial sector tariff structure may reflect characteristics of the industries protected. We seek to identify the...

The barrier model of productivity growth suggests that individual country productivity is related to the world technology frontier disturbed by national barriers. We offer a country study of the barrier model exploiting the dramatic changes in the linkages to the world economy in South Africa....

The experience of liberalized electricity markets’ ability to allocate scarce energy resources has been mixed. In this paper, we analyze how liberalized markets allocate power in the short and long run through the interaction between the spot and end-user markets. We show that totally...

Electricity markets have typically been regulated all over the world. In Europe, UK and Norway have begun to deregulate their electricity markets. Several more countries will probably join them in the near future, for example Finland, Sweden and Spain. The objectives are twofold: to increase...
