A tax on fuel combined with tax-exemptions or subsidies for purchase of fuel-efficient vehicles is implemented in many countries to reduce greenhouse gas emissions and other negative externalities from road traffic. This study, however, shows that a tax on fuel should be combined with heavier...

One country that tries to reduce greenhouse gas emissions may fear that other countries get a competitive advantage and increase emissions (“leakage”). Estimates from computable general equilibrium (CGE) models such as Elliott et al (2010a,b) indicate that 15% to 25% of abatement might be...

In our analytical general equilibrium model where two polluting inputs can be substitutes or complements in production, we study the effects of a tax on one pollutant in two cases: one where both pollutants face taxes and the second where the other pollutant is subject to a permit policy. In...
