Time Discounting and Hand-Sanitization Behavior: Evidence from Japan

Abstract

Whether non-compliance with hand sanitization is related to impatience or impulsivity is an unresolved issue. Several studies have argued that not maintaining hand sanitization requirements during a pandemic could relate to impatience or impulsivity. However, the impatience or impulsivity of hand sanitization needs to be investigated in pandemic-free situations, as government requirements for hand sanitization influence subjective preferences. Little research, however, has examined such associations in pandemic-neutral scenarios. To fill this gap, this study assesses the role of two aspects of time discounting—hyperbolic discounting and impatience—in influencing hand-sanitizing behavior in Japan. The study utilized two waves of 2021 and 2018 datasets derived from the Japanese population-based survey of the Preference Parameters Study of Osaka University (N = 725). The probit regression results provide partial support for deviation from hand sanitization as an impulsive decision because the phenomenon is evident only in females. There were no notable impacts of the impatience variable in any of the models or specifications. Our study provides important policy implications. We argue that one-size-fits-all policies may not solve the impulsivity associated with hand-sanitization behavior in Japan because the impulsivity problem is not commonly found among all respondents. Policymakers should consider underlying gender differences when designing future health-promoting measures.
