This paper analyzes the implications of international knowledge diffusion for the costs of Baltic-wide policy to reduce nutrient emissions to the Baltic Sea. In particular, the impact on the distribution of abatement and costs over time and space is investigated, and the relative importance of...

We analyse effects of uncertain climate change and technological development on cost-effective abatement of nitrogen and phosphorus for a eutrophied sea. A dynamic model is developed which accounts for differences in the sea’s adjustment to the loads of the two nutrients, uncertainty in...

Technical change is an important factor to take into consideration when analysing environmental issues that span over a long time horizon. One important source of technical change is learning-by-doing. The purpose of this paper is to analyse the impact of technical change through...

Heavy loads of nutrients, i.e. nitrogen and phosphorus, cause severe damages in many waters in the world. This paper develops a model for nutrient trading markets for a sea damaged by both nitrogen and phosphorus and faces a dominant polluter of one or both nutrients. The existence of abatement...
