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...

This paper studies the effect of a CDM tree-planting project on carbon sequestration and urban and rural income distribution, taking economy-wide impacts into account. Carbon sequestration in agricultural soil is considered in addition to the carbon in the tree farm itself. The study points to...

Authorities often lack information for efficient regulation of the commons. This paper derives a criterion comparing prices versus tradable quantities in terms of expected welfare, given uncertainty, optimal policy and endogenous cost structure. I show that one cannot determine which regulatory...

This paper conducts Granger-causality tests on real per capita GDP and four types of air emissions (CO2, CO, SO2 and NOx) by using Norwegian data covering the period 1973-2003. The test results indicate that only unidirectional causal relationships exist between GDP and air emissions. For CO2...

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...

We analyze how different ways of allocating emission quotas may influence the electricity market. Using a large-scale numerical model of the Western European energy market, we show that different allocation mechanisms can have very different effects on the electricity market, even if the total...

Given the bleak prospects for a global agreement on mitigating climate change, pressure for unilateral abatement is increasing. A major challenge is emissions leakage. Border carbon adjustments and output-based allocation of emissions allowances can increase effectiveness of unilateral action...

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...

A disaggregated intertemporal CGE model is used to simulate the welfare effects in Norway of the recently implemented trade reforms including the WTO agreement, the EEA treaty, the EFTA fishery agreement and an anticipated EEA resolution on shipbuilding. These reforms affect the Norwegian...

In most applied cost-benefit analyses, individual willingness to pay is aggregated without using explicit welfare weights. This can be justified by postulating a utilitarian social welfare function, along with the assumption of equal marginal utility of income for all individuals. However, since...
