Climate change must deal with two market failures, global warming and learning by doing in renewable use. The social optimum requires an aggressive renewables subsidy in the near term and a gradually rising carbon tax which falls in long run. As a result, more renewables are used relative to...

A cap is imposed on the carbon tax rate if the total tax revenue is not allowed to increase. Using recent data on the carbon-intensity of the economy and the overall tax take, I show that this cap constrains almost any climate policy in at least some countries. A larger number of countries,...

We explore two methods of incorporating bottom-up abatement cost estimates into top-down modeling: economy-wide and sector-specific. Carbon emissions depend basically on technology and scale. Given the technology options, abatement is possible without a substantial reduction in scale. Otherwise...

Climate mitigation policy should be imposed over a long period, and spur development of new technologies in order to make stabilization of green house gas concentrations economically feasible. The government may announce current and future policy packages that stimulate current R&D in...

This paper proposes a new way to model the cost of climate change, based on a vintage capital modeling. Climate change destroys capital, according to the difference between the current climate and the climate that prevailed when a given durable was built. This assumption is meant to account for...

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)...

Demand for oil is very price inelastic. Facing such demand, an extractive cartel induces the highest price that does not destroy its demand, unlike the conventional Hotelling analysis: the cartel tolerates ordinary substitutes to its oil but deters high-potential ones. Limit-pricing equilibria...

Carbon taxes introduce potentially uneven cost burdens across the population. The distribution of these costs is especially important in affecting political outcomes. This paper links dynamic overlapping-generations and microsimulation models of the United States to estimate the initial...

Carbon taxes efficiently reduce greenhouse gas emissions but are criticized as regressive. This paper links dynamic overlapping-generation and microsimulation models of the United States to estimate the initial incidence. We find that while carbon taxes are regressive, the incidence depends much...

The European Union has unilaterally decided to implement a cap & trade scheme to contain greenhouse gases (GHGs) emissions, starting on 1 January 2005. After the First Phase of the Scheme had been concluded on 31 December 2007, emissions from the sectors covered by the European Emissions Trading...
