Effects of Changes in Alcohol Prices and Taxes Effects of Changes in Alcohol Prices and Taxes Alcohol research is carried out from a variety of this section does not contain a comprehensive disciplinary backgrounds and perspectives. From review of earlier research on these topics (such an economic perspective, alcoholic beverages are reviews can be found in Chaloupka 1993; consumer goods, and therefore what is known Chaloupka et al. 1998; Cook and Moore 1993a; about consumer behavior in general is likely to Kenkel and Manning 1996; Leung and Phelps provide insights into alcohol consumption in 1993). In addition, although this section is particular. Perhaps the most basic prediction limited to studies of alcohol prices and taxes, from the economic model of consumer behavior economic research has made other important is that, other things being equal, consumer contributions to the field of alcohol research. demand for a given good falls when the price These include studies of the effect of advertising of that good rises. A large body of research shows on alcohol demand (Saffer 1996); the geographic that this “law of demand” holds for alcoholic relationships between outlet density, alcohol beverages. This means that excise taxes and other availability, and alcohol-related problem rates public policies that affect the price of alcohol can (Gruenewald et al. 1996); the effect of raising influence the demand for alcohol. legal drinking ages on traffic fatalities (Wagenaar 1993); the effects of macroeconomic conditions Because excessive consumption of alcohol has on alcohol consumption and drinking and adverse consequences for health and safety, the driving (Ruhm 1995, 1996); and the relationship consumer response to changes in alcoholic bever- between alcohol consumption and earnings age prices is an especially important topic for (French and Zarkin 1995; Kenkel and Ribar investigation.

An excise tax is based on lems. Taking this approach leads to questions the quantity of alcoholic beverage purchased, in such as: How much does the consumption of contrast to a sales tax, which is based on the price alcoholic beverages fall when prices increase? of a purchased good.

In addition, an excise tax may be passed by private market forces, other public policies, to customers at different rates depending upon and general economic conditions. For example, where the purchase is made, as the price of the alcohol excise tax rates are not routinely increased same beverage can differ widely within a given to compensate for the effects of inflation.

Where somewhat harder to determine. Economists State retailing monopolies exist, the prices of measure consumer response to price changes by alcoholic beverages are under direct government computing the “price elasticity,” defined as the control. Limited evidence suggests that alcoholic percentage change in the quantity demanded beverage prices have, on average, been about the that results from a 1-percent change in price same or only slightly higher in States with (see the box on page 344). monopoly control (Nelson 1990) and that privatization has sometimes, but not always, Price changes seem to affect the demand for resulted in lower prices (MacDonald 1986). beer less than they do the demands for wine and spirits. A 1993 review of 15 studies that Public policies can also indirectly affect alcohol used State and national consumption data found prices by making alcoholic beverage markets more that every 1-percent increase in price translated or less competitive in other ways.
