Money and time are both scarce resources that people believe would bring them greater happiness. But would people prefer having more money or more time? And how does one’s preference between resources relate to happiness? Across studies, we asked thousands of Americans whether they would prefer more money or more time. Although the majority of people chose more money, choosing more time was associated with greater happiness—even controlling for existing levels of available time and money. Additional studies and experiments provide insight into choosers’ underlying rationale and the causal direction of the effect.
