We investigate the socially optimal anthropogenic intervention into the global carbon cycle. The limiting factor for this intervention is the accumulation of carbon in the atmosphere, which causes global warming. We apply a simplified two-box model to incorporate aspects of the global carbon...

I investigate the optimal role of carbon sequestration for mitigation in the presence of a ceiling on atmospheric carbon concentration and consider aspects that have so far only been analyzed in the context of a damage function to measure the consequences of climate change for society. I assume...

This paper explains how, in the context of incomplete coordination among all countries, unilateral policies that might at first sight seem pro-green could actually turn out to harm the global environment. The free-riding motives and the difficulty of reaching an effective international...

We use a two-period model to investigate intertemporal effects of cost reductions in climate change mitigation technologies for the power sector. With imperfect climate policies, cost reductions related to carbon capture and storage (CCS) may be more desirable than comparable cost reductions...

Fossil fuels are non-renewable carbon resources, and the extraction path of these resources depends both on present and future demand. When this Hotelling feature is taken into consideration, the whole price path of carbon fuel will shift downwards as a response to the reduced cost of the...

If investors fear that future carbon taxes will be lower than currently announced by policy makers, long-run investments in greenhouse gas mitigation may be smaller than desirable. On the other hand, owners of a non-renewable carbon resource that underestimate future carbon taxes will postpone...

Arctic oil extraction is inconsistent with the 2°C target. We study unilateral strategies by climate-concerned Arctic countries to deter extraction by others. Contradicting common theoretical assumptions about climate-change mitigation, our setting is one where countries may fundamentally...

If investors fear that future carbon taxes will be lower than currently announced by policy makers, long-run investments in green-house gas mitigation may be smaller than desirable. On the other hand, owners of a non-renewable carbon resource that underestimate future carbon taxes will postpone...

Fossil fuels are non-renewable carbon resources, and the extraction path of these resources depends both on present and future demand. When this 'Hotelling feature' is taken into consideration, the whole price path of carbon fuel will shift downwards as a response to the reduced cost of the...
