“…In terms of well-being, some research shows no lasting effect of income (Easterlin, Morgan, Switek, & Wang, 2012) but an effect of well-being on income via employment and other factors (Binder & Coad, 2010;De Neve & Oswald, 2012;Michaud & Van Soest, 2008;Oswald, Proto, & Sgroi, 2015). Still other studies find bidirectional causality or "feedback" effects (e.g., Chen, Clarke, & Roy, 2014;Devlin & Hansen, 2001;Erdil & Yetkiner, 2009;French, 2012), which many researchers propose should exist for various reasons (e.g., Deaton, 2003;Diener, 2012).…”
