Long-Run Effects of Lottery Wealth on Psychological Well-Being
研究瑞典彩票中奖者5-22年后的心理状况，发现大奖得主总体生活满意度持续提升超十年，但幸福感和心理健康改善较小，财务满意度是重要中介。
Abstract We surveyed a large sample of Swedish lottery players about their psychological well-being 5–22 years after a major lottery event and analysed 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 over time. The estimated treatment effects on happiness and mental health are significantly smaller. Follow-up analyses of domain-specific aspects of life satisfaction implicate financial life satisfaction as an important mediator for the long-run increase in overall life satisfaction.
