Income and emotional well-being: Evidence for well-being plateauing around $200,000 per year

Is emotional well-being monotonically increasing in the level of income or does it reach a plateau at some income threshold, whereafter additional income does not contribute to further well-being? Using a data-driven approach to detect the placement of the threshold, we find a flat relationship between household income and emotional well-being above a threshold around $200,000 per year. Our analysis relies on a number of assumptions, which we briefly discuss. We conclude that although the analysis of this paper provides some evidence for well-being plateauing around $200,000 per year, more research is needed before any definite conclusions about the relationship between emotional well-being and income can be drawn.
