Summary

This 1989 memorandum by David Skinner evaluates the potential impact of proposed Federal excise tax increases and equalizations on alcoholic beverages regarding highway fatalities. Motivated by recommendations from former Surgeon General C. Everett Koop to raise and equalize taxes based on alcohol content, the paper addresses the uncertainty surrounding the magnitude of fatality reductions. While it is theoretically established that higher alcohol prices reduce consumption and subsequently accidents, the specific quantitative effect of simultaneous tax changes across all beverage types remains difficult to predict due to substitution effects and historical data limitations. The study employs both theoretical reasoning and empirical analysis. Theoretically, Skinner identifies three critical links for tax effectiveness: the tax must raise retail prices, higher prices must reduce consumption, and the reduced consumption must involve alcohol linked to crashes. He notes that previous studies often overestimate effects by focusing on single beverages, ignoring substitution to cheaper alternatives. Empirically, the paper reviews four existing studies—Cook, Walsh, Saffer and Grossman, and Phelps—and conducts original cross-sectional analyses using 1984 data from 31 alcohol-license states. These analyses regressed highway fatality rates and the percentage of dead drivers with positive blood alcohol content (BAC) against tax rates for distilled liquor, wine, and beer, controlling for variables such as vehicle miles traveled and income. The findings indicate that widely cited elasticity estimates, particularly Cook’s median estimate of a 0.7 percent reduction in all highway fatalities for every 1 percent increase in distilled liquor tax, likely overstate the impact of proposed national tax changes. Skinner argues that historical state tax changes allowed for beverage substitution, whereas proposed equalized taxes would limit this, thereby reducing the overall consumption drop. Furthermore, the original cross-sectional regressions found no statistically significant association between higher state alcohol tax rates and lower fatality rates or lower percentages of drivers with positive BAC levels. This lack of correlation is attributed to the fact that historical taxation was designed for revenue generation rather than significant consumption reduction, meaning existing tax levels were insufficient to produce detectable safety impacts. The significance of this work lies in its caution against relying on historical elasticity estimates to forecast the effects of new, comprehensive tax policies. Skinner concludes that while higher alcohol prices will reduce fatalities, the exact magnitude is unpredictable and likely lower than previous calculations suggest. The paper highlights that alcohol taxation is a "blunt" instrument that affects all consumers, not just those engaging in harmful behavior, and notes that beer consumption has the strongest link to highway fatalities. Consequently, the study suggests that while tax increases are justified by the social costs of alcohol misuse, policymakers should not expect the dramatic fatality reductions implied by earlier, more optimistic empirical models.

Key finding

Higher state alcohol tax rates were not significantly associated with lower highway fatality rates or lower percentages of deceased drivers with positive blood alcohol levels in 1984 cross-sectional data.
