We analyze a dynamic stochastic general equilibrium model which includes a negative externality that arises from fossil fuels burnings. The carbon released to the atmosphere by electricity producers is the main driver of climate change. We adapt the optimal tax derived by Golosov et al. (2011)...

Optimal climate policy is studied in a Ramsey growth model with exhaustible oil reserves, an infinitelyelastic supply of renewables, stock-dependent oil extraction costs and convex climate damages. Weconcentrate on economies with an initial capital stock below that of the steady state of the...

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 permanently...

During recent years increased attention has been given to second-generation wood-based bioenergy. The carbon stored in the forest is highest when there is little or no harvest from the forest. Increasing the harvest from a forest, in order to produce more bioenergy, may thus conflict with the...

The paper compares the effects of market-based and command-and-control climate policies on the direction of technical change and the prevention of environmental disasters. Drawing on the model proposed in Acemoglu et al. (2012, American Economic Review), we show that market-based policies...

This dissertation deals with the complex and multifaceted issue of climate change and climate policy. Since the problem touches upon many disciplines and also subfields within economics, the present study tries to bridge the gaps between different areas and dimensions of economic analysis....

Recent contributions have questioned whether biofuels policies actually lead to emissions reductions, and thus lower climate costs. In this paper we make two contributions to the literature. First, we study the market effects of a renewable fuel standard. Opposed to most previous studies we...

This paper develops sufficient conditions under which the Weak Green Paradox may (and may not) hold in terms of subsidies for biofuel production such that the supply-side responses by fossil fuel producers may more than offset the substitution to biofuels. Analytical results are derived and...

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...

Optimal climate policy is studied. Coal, the abundant resource, contributes more CO2 per unit of energy than the exhaustible resource, oil. We characterize the optimal sequencing oil and coal and departures from the Herfindahl rule. 'Preference reversal' can take place. If coal is very dirty...
