Long-run Effects of Lottery Wealth on Psychological Well-being

Here is a new NBER working paper from Erik Lindqvist, Robert Östling, and David Cesarini:

We surveyed a large sample of Swedish lottery players about their psychological well-being and analyzed the data following pre-registered procedures. Relative to matched controls, large-prize winners experience sustained increases in overall life satisfaction that persist for over a decade and show no evidence of dissipating with time. The estimated treatment effects on happiness and mental health are significantly smaller, suggesting that wealth has greater long-run effects on evaluative measures of well-being than on affective ones. Follow-up analyses of domain-specific aspects of life satisfaction clearly implicate financial life satisfaction as an important mediator for the long-run increase in overall life satisfaction.

In other words, it is good to have more money.
