Problem gamblers discount delayed rewards more rapidly than do non-gambling controls. Understanding this impulsivity is important for developing treatment options. In this article, we seek to make two contributions: First, we ask which of the currently debated economic models of intertemporal choice (exponential versus hyperbolic versus quasi-hyperbolic) provides the best description of gamblers’ discounting behavior. Second, we ask how problem gamblers differ from habitual gamblers and non-gambling controls within the most favored parametrization. Our analysis reveals that the quasi-hyperbolic discounting model is strongly favored over the other two parametrizations. Within the quasi-hyperbolic discounting model, problem gamblers have both a significantly stronger present bias and a smaller long-run discount factor, which suggests that gamblers’ impulsivity has two distinct sources.

问题赌博中的折扣行为

问题赌徒比非赌博控制者更快地折扣延迟奖励。了解这种冲动对于制定治疗方案很重要。在这篇文章中,我们试图做出两项贡献:首先,我们询问目前争论不休的跨期选择经济模型(指数、双曲线和准双曲线)中的哪一个能够最好地描述赌徒的折扣行为。其次,我们询问问题赌徒与习惯性赌徒以及最喜欢的参数化中的非赌博控制有何不同。我们的分析表明,准双曲线贴现模型比其他两个参数化模型更受青睐。在准双曲线贴现模型中​​,问题赌徒有明显更强的当前偏差和更小的长期贴现因子,
