The Clean Development Mechanism (CDM) is an offset mechanism designed to reduce the overall cost of implementing a given target for greenhouse gas (GHG) emissions in industrialized Annex B countries of the Kyoto Protocol, by shifting some of the emission reductions to Non-Annex B countries. This...

We study interactions between a "policy bloc's" emissions quota market and an offset market where emissions offsets can be purchased from a non-policy "fringe" of countries (such as for the CDM under the Kyoto Protocol). Policy-bloc firms are assumed to benefit from free quota allocations that...

Popular instruments to regulate consumption of oil in the transport sector include fuel taxes, biofuel requirements, and fuel efficiency. Their impacts on oil consumption and price vary. One important factor is the market setting. We show that if market power is present in the oil market, the...

Given the bleak prospects for a global agreement on coordinated policies to mitigate climate change, political pressure is increasing among industrialized countries for unilateral abatement. A major challenge thereby is the appropriate response to the threat of emissions leakage. Border carbon...

Abatement can be performed by measures that have an impact on present emissions, but no lasting effect, and by long-lived infrastructure investments. We study the optimal combination of short and long-lived options for reducing greenhouse gas (GHG) emissions, by specifying abatement cost...

The "resource curse" is a potential threat to all countries relying on export income from abundant natural resources such as fossil fuels. The early literature hypothesized that easily accessible natural resources would lead to lack of technological progress. In this article we instead propose...

Countries with ambitious climate targets are concerned about carbon leakage to countries with more lenient or no carbon pricing. A common policy measure against leakage is output-based allocation of emissions allowances, whose effectiveness could be further enhanced by consumption taxes levied...

The environmental impacts on an economy is studied over time using endogenous growth theory. Externalities from the environment on production are central in the analysis, and we examine whether an optimal path realizes more rapid economic growth. The paper is mainly focusing on developing...

The aim of this paper is to examine the impacts of a global carbon tax on fossil fuel markets. In particular, the effect on the Norwegian, as well as the global, petroleum wealth is studied. Most empirical models of fossil fuel markets either use an exogenous price path, or model the supply side...

In this paper we ask whether OPEC still gains from cartelisation in the oil market despite low producer prices and a modest market share. We apply two intertemporal equilibrium models of the global oil market; one consisting of a cartel and a fringe, and one describing a hypothetical competitive...
