Efficiency and Equity of Fuel Taxes with Increasing Electric-powered Vehicle Adoption University of Navarra, Spain Fuel taxes are widely used to internalize the externalities of driving, particularly environmental ones. However, the higher upfront price of cleaner, more fuel-efficient vehicles raises concerns about the potentially regressive nature of these taxes, as lower-income households may face greater financial constraints to adopting such vehicles. I examine the efficiency and equity implications of fuel taxes by exploiting substantial temporal and cross-sectional variation in Spain. I find that a 1-cent increase in the fuel tax reduces CO2 emissions from the vehicle fleet by approximately 0.13%, primarily driven by increased adoption of electric-powered vehicles. However, this response is disproportionately concentrated among higher-income households, while lower-income households exhibit little to no change in their vehicle choices. Despite this disparity, I document that the tax savings accruing to wealthier households are modest and are far outweighed by the higher upfront costs of electric-powered vehicles. These findings suggest that while fuel taxes are an effective instrument for reducing emissions, they do not substantially alter the distribution of the burden across income groups. | |
