Following new legislation the Swedish electricity market is about to be deregulated. The new system is designed to ensure competition in production and supply. The Swedish electricity market is characterised by a high degree of concentration on the seller side. In this paper we use a simple...

Estimation of emission control cost functions is often carried out in a partial equilibrium framework, i.e., under the assumption that emission control measures have negligible effects on input and output prices. In this paper a computable general equilibrium model is used for simulation of the...

The purpose of this paper is to quantitatively evaluate the impact on electricity prices of deregulation and free trade in the Nordic countries. The analysis is focused on the impact of increased competition on market power and the degree of monopolistic pricing. The major tool for our analysis...
