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 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...

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...

Researchers have utilized the fact that many states have term limits (as opposed to being eligible for re-election) for governors to determine how changes in electoral incentives alter state regulatory agency behavior. This paper asks whether these impacts spill over into private sector...

I examine a policy-making game among countries that must choose both a policy instrument (e.g., a tax or a quota) and its intensity (i.e., the tax rate or the quota level) to price pollution. When countries price pollution non-cooperatively, they not only set the intensity inefficiently, they...

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...

This paper is the first to investigate the effectiveness of fuel taxation to jointly deliver climate and health benefits in a quasi-experimental setting. Using the synthetic control method, we compare carbon and air pollutant emissions of the actual and synthetic German transport sector...
