The Long-Run Impact of Cash Transfers to Poor Families
利用美国首个政府福利项目（1911-1935年）的行政记录，发现现金转移使贫困家庭男孩寿命延长一年，教育年限增加三分之一，成年后收入更高。
We estimate the long-run impact of cash transfers to poor families on children's longevity, educational attainment, nutritional status, and income in adulthood. To do so, we collected individual-level administrative records of applicants to the Mothers' Pension program—the first government-sponsored welfare program in the United States (1911–1935)—and matched them to census, WWII, and death records. Male children of accepted applicants lived one year longer than those of rejected mothers. They also obtained one-third more years of schooling, were less likely to be underweight, and had higher income in adulthood than children of rejected mothers.
