Although the United States provides unpaid maternity and family leave to qualifying workers, it is the only OECD country without a national paid leave policy, making wage replacement a pivotal issue under debate. We use ten years of linked administrative data from California together with a...

Considerable research attention has been devoted to the question of whether and to what extent changes in welfare policy legislated in the 1990s might have deterred immigrant participation in welfare programs, although only post-1996 immigrants were explicitly targeted by most of the changes....

In this paper, I examine the impact of uninsured patients on the health of the insured, focusing on one health outcome - the in-hospital mortality rate of insured heart attack patients.

Using recent data from southern California and Mexico we challenge the notion that the demographic profile of post-1970 Mexican migrants to the United States has remained constant. We find that more recent cohorts of migrants: (1) are more likely to settle permanently in the United States, (2)...

Many U.S. cities have recently increased their minimum wages, especially in California. We report results from carrying out analyses of the impacts of these city minimum wages, as specified in a pre-analysis plan (PAP) that was registered on Open Science Framework prior to the release of data...

This paper provides quasi-experimental evidence on the impact of paid leave legislation on fathers' leave-taking, as well as on the division of leave between mothers and fathers in dual-earner households. Using difference-in-difference and difference-in-difference-in-difference designs, we study...
