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...

In this study CO2 emissions embodied in Austrian international trade are quantified employing a 66-region input output model of multidirectional trade. We find that Austria's final demand CO2 responsibilities on a global scale are 38% higher than conventional statistics report (110 Mt-CO2 versus...

Intensity standards have gained substantial momentum as a regulatory instrument in US climate policy. Based on numerical simulations with a large-scale computable general equilibrium model we show that intensity standards may rather increase than decrease counterproductive carbon leakage....
