This paper discusses the interplay between the choice of the discount rate, greenhouse gas mitigation and endogenous technological change. Neglecting the issue of uncertainty it is shown that the green golden rule stock of atmospheric carbon is uniquely determined, but is not affected by...

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...

In this paper we focus on how an international climate treaty will influence the exploration of oil in Non-OPEC countries. We present a numerical intertemporal global equilibrium model for the fossil fuel markets. The international oil market is modelled with a cartel (OPEC) and a competitive...

During the last decade, Norway has carried out an ambitious climate policy. The main policy tool is a relatively high carbon tax, which was implemented already in 1991. Data for the development in CO2 emissions since then provide a unique opportunity to evaluate carbon taxes as a policy tool. To...

Information about total electricity consumption is available for most households. However, the electricity consumption related to different end uses, e.g. space heating, water heating, lighting and services from household appliances are usually not metered. Metering data are very costly to...

This paper analyses the demand response from residential electricity consumers to a demand charge grid tariff. The tariff charges the maximum hourly peak consumption in each of the winter months January, February and December, thus giving incentives to reduce peak consumption. We use hourly...

This paper examines how ambitious climate policies and subsidies to carbon capture may affect international energy prices and market shares in the power market. A detailed numerical model of the international energy markets is used. We first conclude that an ambitious climate policy alone will...

We examine the potential of Carbon Capture and Storage (CCS) technologies in the European electricity markets, assessing whether CCS technologies will reduce carbon emissions substantially in the absence of investment subsidies, and how the availability of CCS technologies may affect electricity...

It is costly and difficult to meter electricity consumption for different end uses, e.g. space heating, lighting and household appliances. We deduce a model for using cross-sectional data for total annual electricity consumption for a sample of households, together with information from energy...
