This paper examines how the public policy environment in the United States affects work by new mothers following childbirth. We examine four types of policies that vary across states and affect the budget constraint in different ways. The policy environment has important effects, particularly for less advantaged mothers. There is a potential conflict between policies aiming to increase maternal employment and those maximizing the choices available to families with young children. However, this tradeoff is not absolute since some choice-increasing policies (generous child care subsidies and state parental leave laws) foster both choice and higher levels of employment.

Utilizing data from the June Current Population Survey (CPS) Fertility Supplement merged with data from other months of the CPS, we describe trends in parents' employment and leave-taking after birth of a newborn and analyze the extent to which these behaviors are associated with parental leave policies. The period we examine -- 1987 to 2004 -- is one in which such policies were expanded at both the state and federal level. We also provide the first comprehensive evidence as to how these expansions are correlated with employment and leave-taking for both mothers and fathers over this period. Our main finding is that leave expansions have increased the amount of time that new mothers and fathers spend on leave, with effects that are small in absolute terms but large relative to the baseline...
