Source: Author’s calculations based on on the 1984–1986, 1996, 2004, and 2008 Survey of Income and Program Participation panels.
Notes: Women age eighteen to forty-five who give birth during the panels. Plots show proportion working part time (less than thirty-five hours a week) conditional on working from twenty-four months before to twenty-four months after birth (plotting the coefficients from equation (1) with the dependent variable an indicator for working part-time estimated separately by education and parity).
