This article compares the effects of two policies aimed at promoting e
fficiency in the taxation of alcoholic beverages. One policy is to set
alcohol tax rates at a level that corrects for excessive social costs
of alcohol consumption. The second is to view alcohol taxes as a subs
titute for other taxes and apply the prescriptions of optimal tax theo
ry to attain the efficient mix of tax revenues. Estimates of the diffe
rential effects of the two policies suggest that the second policy req
uires a higher tax rate on alcohol and produces a greater welfare gain
.
