Material resources and well-being — Evidence from an Ethiopian housing lottery
利用埃塞俄比亚大规模住房抽奖的自然实验，比较中奖者和未中奖者的福祉变化，发现物质改善提高了生活满意度、降低了财务压力，但对心理困扰无显著影响。
Do better material conditions improve well-being and mental health? Or does any positive relationship merely reflect that well-being promotes economic success? We compare winners and losers from a large Ethiopian housing lottery in a preregistered analysis. Winners gain access to better housing, experience a substantial increase in wealth, and report higher levels of overall life satisfaction and lower levels of financial distress. However, we find no average effects of winning on psychological distress. Our results suggest that not all aspects of well-being and mental health are equally sensitive to economic conditions.
