RT Journal Article SR Electronic T1 Can Social Security Explain Trends in Labor Force Participation of Older Men in the United States? JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 328 OP 363 DO 10.3368/jhr.45.2.328 VO 45 IS 2 A1 Blau, David M. A1 Goodstein, Ryan M. YR 2010 UL http://jhr.uwpress.org/content/45/2/328.abstract AB 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.
