两项研究比较了参与者，根据他们的典型饮酒量，他们对延迟的假设金额的价值的折扣程度。研究1中的重度社交饮酒者和研究2中的问题饮酒者都表现出比轻度社交饮酒者更大的时间折扣;这种差异在研究2中更强。两项研究都发现，双曲函数比指数函数更准确地描述了时间贴现。这些结果是一致的扩展行为理论的跨期选择的特点，酒精消费的决定因素。贴现差异也与更一般的行为经济学和成瘾的经济学理论相一致，尽管双曲线函数形式与经济学理论中的指数贴现函数不一致。饮酒者群体在冲动性和时间取向问卷上也存在差异，轻度饮酒者的冲动性较低，更倾向于未来;然而，这些措施与时间折扣的措施并没有很强的相关性。
Two studies compared participants, distinguished by their typical alcohol consumption, on the degree to which they discounted the value of delayed, hypothetical amounts of money. Heavy social drinkers in Study 1 and problem drinkers in Study 2 both showed greater temporal discounting than light social drinkers; this difference was stronger in Study 2. Both studies found that a hyperbolic function described temporal discounting more accurately than an exponential function. These results are consistent with extending behavioral theories of intertemporal choice to characterize the determinants of alcohol consumption. The discounting differences also are consistent with more general behavioral economic and economic theories of addiction, although the hyperbolic functional form is inconsistent with the exponential discounting function in economic theory. The drinker groups also differed on impulsiveness and time orientation questionnaires, with light drinkers being less impulsive and more future oriented; however, these measures were not strongly correlated with the measure of temporal discounting.
