Source: Author’s calculations based 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 and their spouse. Wives are women who were married with spouse present in the month they gave birth. Plots show labor-force participation from twelve months before to twenty-four months after birth (plotting the coefficients added to the constant from equation (1) with the dependent variable an indicator for being in the labor force estimated separately by marital status, education, and parity).
