Paul J. Burke and Shuhei Nishitateno:
This study utilizes data for 144 countries from 1991 to 2010 to present the first international estimates of the gasoline price elasticity of road fatalities. We instrument each country's gasoline price with that country's oil reserves and the yearly international crude oil price to address potential endogeneity concerns. Our findings suggest that the average reduction in road fatalities resulting from a 10% increase in the gasoline pump price is in the order of 3%–6%. Around 35,000 road deaths per year could be avoided by the removal of global fuel subsidies. (JEL R41, H23, O18, Q43)
At a value of statistical life of $9 million (that was the number Kip Viscusi was using a the SBCA meetings in March, removing global fuel subsidies would generate a life saving benefit of $315 billion.

Policies to reduce carbon emissions by vehicles, such as fuel economy standards and gasoline taxes, have impacts on vehicle weight and thus on safety. This paper develops a model that separately identifies the impact of vehicle weight on mortality and selection effects that impact accident propensity. The main results are that (1) the safety externalities associated with heavy vehicles are greater than the environmental ones; (2) under fuel economy standards, vehicle weights have recently decreased with little likely effect on accident deaths; and (3) similar environmental benefits could be combined with substantial reductions in deaths by implementing higher gasoline taxes. (JEL H23, D62)
A higher gas tax would generate substantial life saving benefits too.
