New money, no money, and psychological inheritance in the elasticity of 21st century happiness

The role of financial resources in subjective well-being is extensively studied, yet with many unresolved debates on the precise association, inflection points, or applications. Using multidimensional data from 91 countries (N=53,589), we find near-universal support for a positive association, which is strongest in wealthier countries and, globally, highly elastic as household incomes surpass local costs of living. Uniquely, we observe a “psychological inheritance”, where the strongest associations are determined by economic class in childhood, even after significant upward mobility by adulthood. We also find inelasticity in well-being at the top and bottom of income distributions, which largely indicates satiation and decoupling at wealth extremes. Across countries, well-being surpasses average at household incomes around 4.5 times the cost of living. Downward mobility is linked with substantial declines but likewise better outcomes than those of equivalent adult incomes that started lower economically, suggesting a psychological endowment where starting point and relative stability are as vital as growth, though the association is strongest in wealthier countries. The link between income and well-being is therefore strongly supported while personal financial history and broader economic environment have substantial impacts on how money relates to happiness, and thus, to individual and population well-being.
