Understanding the Increase in Disability Insurance Benefit Receipt in the United States
分析了美国联邦残疾保险项目中劳动年龄人口领取福利比例从1970年代末的2.2%升至2013年的4.6%的原因，并回顾了经济学家提出的改革方案，对关注社会保障和公共政策的研究者具有参考价值。
The share of working-age Americans receiving disability benefits from the federal Disability Insurance (DI) program has increased significantly in recent decades, from 2.2 percent in the late 1970s to 3.6 percent in the years immediately preceding the 2007–2009 recession and 4.6 percent in 2013. With the federal Disability Insurance Trust Fund currently projected to be depleted in 2016, Congressional action of some sort is likely to occur within the next several years. It is therefore a good time to sort out the competing explanations for the increase in disability benefit receipt and to review some of the ideas that economists have put forth for reforming US disability programs.
