After half a century of sustained growth, female labor force participation has decelerated in Latin America, especially among married vulnerable women. Based on a large database of microdata from household surveys, this paper documents this recent deceleration and provides evidence on the determinants. We argue that the fast economic growth experienced by the region in the 2000s was an important driving force: lower unemployment and higher earnings of male partners plus increased social assistance may have reduced the pressing need for vulnerable women to take low-quality jobs.
