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 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...

The environmental Kuznets curve (EKC) has been the dominant approach among economists to modeling aggregate pollution emissions and ambient pollution concentrations over the last quarter century. Despite this, the EKC was criticized almost from the start and decomposition approaches have been...
