A formula is derived for the social cost of carbon (SCC) that takes account of intragenerational income inequality and its evolution with economic growth. The social discount rate (SDR) should be adjusted to account for intragenerational and intergenerational inequality aversion and for risk...

This paper measures environmental efficiency (EE) and environmental productivity (EP) and analyzes differences in these across countries. It explores the macro-economic factors that could explain these differences and whether these differences can be explained by income levels and by the degree...

In this paper, we use an integrated assessment model to examine the implications of not recognizing, and partially recognizing forest carbon in climate policy. Specifically, we investigate the impact of an asymmetric carbon policy that recognizes emissions from fossil fuels while ignoring...

The optimal transition to a low-carbon economy must account for adjustment costs in switching from dirty to clean capital, technological progress, and economic and climatic shocks. We study the low-carbon transition using a dynamic stochastic general equilibrium model with emissions abatement...

A central issue in climate policy is the question whether long-term targets for green- house gas emissions should be adopted. This paper analyzes strategic effects related to the timing of such commitments. Using a two-country model, we identify a redistributive effect that undermines long-term...

We develop and implement a new method for identifying wasted subsidies, and use it to provide systematic evidence on the misallocation of carbon offsets in the Clean Development Mechanism - the world's largest carbon offset program. Using newly constructed data on the locations and...
