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 com-parable cost reductions...

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...

The Green Paradox states that, in the absence of a tax on CO2 emissions, subsidizing a renewable backstop such as solar or wind energy brings forward the date at which fossil fuels become exhausted and consequently global warming is aggravated. We shed light on this issue by solving a model of...

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...

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...

Carbon pricing regulates emission flows and collects rents from underlying fossil resource stocks. The resulting investment shift implies lower climate policy costs and improved welfare if capital is underaccumulated. We prove that under emission trading, such a beneficial macroeconomic...

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 governments cannot commit to future carbon tax rates, investments in greenhouse gas mitigation will be based on uncertain and/or wrong predictions about these tax rates. Predictions about future carbon tax rates are also important for decisions made by owners of non-renewable carbon...

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 com-parable cost reductions...

The focus of the green paradox literature has been either on demand-side climate policies or on effects of technological changes. The present paper addresses the question of whether there also might be some kind of green paradox related to supply-side policies, i.e. policies that per-manently...
