We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries' growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...

Carbon taxes remain economists favoured policy tool to curb emissions, but are unpopular among segments of the populations. Theoretical and numerical work tends to show the effectiveness of carbon taxes, but ex-post empirical analyses are still rare. In this paper we attempt to bridge this gap....

We analyze the impact of carbon prices on human capital accumulation, sectoral change, and economic growth. In our framework output is produced with dirty and/or clean technologies using skilled and unskilled labor as inputs. Carbon policy affects technology selection which transmits incentives...

We study the effects of greenhouse gas emissions on optimum growth and environmental policy by using an expansion-in-varieties growth model with polluting non-renewable resources. Climate change harms the capital stock. Our main contribution is to introduce and extensively explore the naturally...
