This paper investigates how greenhouse gas (GHG) policy stringency affects anthropogenic CO2 emissions using a new GHG policy stringency indicator and a structural spatial VAR approach. We estimate an average country-specific elasticity of CO2 emissions to GHG policy stringency, and assess the...

The standard approach to the Environmental Kuznets Curve (EKC) holds that as a country develops and GDP per capita grows environmental degradation initially increases but eventually it reaches a turning point where environmental degradation begins to decline. Environmental degradation takes many...

Multi-gas approaches to climate change policies require a metric establishing "equivalences" among emissions of various species. Climate scientists and economists have proposed four classes of such metrics and debated their relative merits. We present a unifying framework that clarifies the...
