%0 Report %A Costa-Font, Joan %A Flèche, Sarah %A Pagan, Ricardo %T The Welfare Effects of Time Reallocation: Evidence from Daylight Saving Time %D 2021 %8 2021 Jul %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 14570 %U https://www.iza.org/publications/dp14570 %X Daylight Saving Time (DST) is currently implemented by more than seventy countries, yet we do not have a clear knowledge of how it affects individuals' welfare. Using a regression discontinuity design combined with a differences-in-differences approach, we find that the Spring DST causes a significant decline in life satisfaction. By inducing a reallocation of time, the transition into DST deteriorates sleep and increases time stress, which in turn affects physical and emotional health. After performing a simple cost-benefit analysis, we find evidence suggestive that ending DST would exert a positive effect on welfare, namely the wellbeing costs associated with DST exceed its benefits. %K Daylight Saving Time %K wellbeing %K health %K sleep %K time stress
