There has been a tremendous growth in research related to happiness and well-being in recent years, and an influential stream of this research has concerned itself with international differences in happiness. Our goal here is to describe some of the reasons happiness research is important to organizational researchers for both theoretical and practical purposes. We also describe significant methodological issues that should be considered when assessing these relationships at the group level. Finally, we provide suggestions for future research that might productively integrate insights from the organizational literature into happiness studies.
