Abstract
Two studies compared participants, distinguished by theirtypical alcohol consumption, on the degree to which they discountedthe value of delayed, hypothetical amounts of money. Heavy socialdrinkers in Study 1 and problem drinkers in Study 2 both showedgreater temporal discounting than light social drinkers; thisdifference was stronger in Study 2. Both studies found that ahyperbolic function described temporal discounting more accuratelythan an exponential function. These results are consistent withextending behavioral theories of intertemporal choice tocharacterize the determinants of alcohol consumption. Thediscounting differences also are consistent with more generalbehavioral economic and economic theories of addiction, although thehyperbolic functional form is inconsistent with the exponentialdiscounting function in economic theory. The drinker groups alsodiffered on impulsiveness and time orientation questionnaires, withlight drinkers being less impulsive and more future oriented;however, these measures were not strongly correlated with themeasure of temporal discounting.
