Editing Time preference (section)

=== Race ===
Race is also thought to play a role in time preference. Andreoni et al. find that a child’s ability to wait for a larger later reward was correlated with race. They did this by asking the children a series of decisions in which they could choose candy that same day or a larger amount of candy which they would receive on the next day. In analyzing the data by race, they found that black children, across all ages, were more likely to make impatient decisions than other races.<ref>{{Cite journal |last1=Andreoni |first1=James |last2=Kuhn |first2=Michael A. |last3=List |first3=John A. |last4=Samek |first4=Anya |last5=Sokal |first5=Kevin |last6=Sprenger |first6=Charles |date=2019-09-01 |title=Toward an understanding of the development of time preferences: Evidence from field experiments |url=https://www.sciencedirect.com/science/article/abs/pii/S004727271930091X |journal=Journal of Public Economics |volume=177 |pages=104039 |doi=10.1016/j.jpubeco.2019.06.007 |issn=0047-2727}}</ref> In more specific contexts, race was also found to play a role. In a study of the utility of long term water quality improvements, Viscusi et al. find that black respondents displayed higher discounting than other racial groups.<ref>{{Cite journal |last1=Viscusi |first1=W.
