A tax on fuel combined with tax exemptions or subsidies for fuel-efficient vehicles is implemented in many countries to fulfill the Paris agreement and to curb mileage-related externalities from road traffic. The present study shows that a tax on fuel should be combined with heavier taxation of...

While environmental taxes aim at making environmentally harmful behaviour more costly, the opposite is true for environmentally beneficial tax incentives. Tax incentives imply foregone public revenues to favour less polluting consumption and investment activities in order to achieve...

We study the implications of climate change and the associated mitigation measures for optimal monetary policy in a canonical New Keynesian model with climate externalities. Provided they are set at their socially optimal level, carbon taxes pose no trade-offs for monetary policy: it is both...

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...

To mitigate climate change, some governments opt for instruments focused on investment, like performance standards or feebates, instead of carbon prices. We compare these policies in a Ramsey model with clean and polluting capital, irreversible investment and a climate constraint. Alternative...
