Can Social Security Explain Trends in Labor Force Participation of Older Men in the United States?
研究了美国社会保障规则变化对老年男性劳动参与率的影响，发现1960-80年代福利增加仅解释一小部分下降，而提高全额退休年龄和延迟退休积分解释了近期增长的四分之一到一半。
After a long decline, the Labor Force Participation Rate (LFPR) of older men in the United States leveled off in the 1980s, and began to increase in the late 1990s. We examine how changes in Social Security rules affected these trends. We attribute only a small portion of the decline from the 1960s-80s to the increasing generosity of Social Security over this period. Increases in the Full Retirement Age and the Delayed Retirement Credit explain one quarter to one half of the recent increase in the LFPR. Increasing educational attainment and increasing LFPR of married women also contributed to the recent rise.
