We provide ex-post empirical analysis of the effects of climate policies on carbon dioxide emissions at the aggregate national level. Our results are based on a comprehensive database of 121 countries. As climate policies we examine carbon taxes and emissions trading systems (ETS), as well as...

We introduce a "smart" cap and trade system that eliminates the welfare costs of asymmetric information (“uncertainty”). This cap responds endogenously to technology or macroeconomic shocks, relying on the market price of certificates to aggregate information. It allows policy makers to...

We examine an open economy's strategy to reduce its carbon emissions by replacing its consumption of coal - very carbon intensive - with gas - less so. Unlike the standard theoretical approach to carbon leakage, we show that unilateral CO2 reduction policies generate a higher leakage rate in the...

We examine an open economy's strategy to reduce its carbon emissions by replacing its consumption of coal - very carbon intensive - with gas - less so. Unlike the standard analysis of carbon leakage, unilateral carbon-reduction policies with more than one carbon energy source may turn...

Carbon tariffs are one prominently discussed environmental policy. The proponents stress the carbon tariffs' ability to mitigate the potential negative effect of environmental-friendly production on competitiveness, to avoid carbon leakage and to reduce world carbon emissions. We analyze the...
