Sheehan-Connor Advocates in Orlando Sentinel for Raising the Gas Tax

Assistant Professor of Economics Damien Sheehan-Connor is the author of an oped in the Orlando Sentinel (available to subscribers) arguing that raising the gas tax would not only help the environment, but would save lives on the road.

Sheehan-Connor considers the findings of a new study out by the National Safety Council, which suggested that automobile accidents are on the rise again after years of decline. While many factors could potentially contribute to this reversal, he writes that it’s likely that two seemingly positive developments–lower gas prices and stricter fuel economy standards imposed by the government–have played an important role. How? Lower gas prices have encouraged consumers to buy bigger, less fuel-efficient vehicles, while government regulations require automakers to produce lighter, more fuel-efficient vehicles. The end result: greater divergence in the weights of vehicles on the road.

He writes: “Whether a given two-vehicle accident is fatal depends critically on how well matched are the weights of the vehicles involved. The results of a paper I authored in last month’s Economic Inquiry make the point starkly. It found that in severe accidents between two vehicles of average weight, 25 percent of vehicle drivers are expected to die. But in severe accidents between full-size pickup trucks and compact cars, the death rate is a whopping 40 percent—or 60 percent higher.”

To counter this, Sheehan-Connor suggests turning to higher gas taxes, rather than stricter fuel economy standards.

The politics of gasoline taxes are difficult, but the benefits are compelling. First, the environmental benefits from reduced carbon emissions would exceed the cost of foregone gasoline consumption. Second, the efficiency of the tax system could be improved by implementing the tax in a revenue-neutral fashion. Income tax rates, which do impose some efficiency costs to the economy, could be lowered and the revenue replaced by the gasoline tax, which has efficiency benefits. Third, gasoline taxes are far simpler, and thus less costly to implement, than the 577 pages of regulations that make up the most recent fuel economy standards. And finally, our roadways would be made safer. Other than the word “tax,” what’s not to like?
