From the abstract:
In 1990, the US had the sixth highest female labor participation rate among 22 OECD countries. By 2010, its rank had fallen to 17th. We find that the expansion of “family-friendly” policies including parental leave and part-time work entitlements in other OECD countries explains 28-29% of the decrease in US women’s labor force participation relative to these other countries. However, these policies also appear to encourage part-time work and employment in lower level positions: US women are more likely than women in other countries to have full time jobs and to work as managers or professionals.
