The effective tax on earnings embodied in the Social Security retirement earnings test has been as high as 50 percent. Despite numerous empirical studies, there is surprisingly little agreement about whether the earnings test affects male labor supply. In this paper, the authors provide a...

This paper tests whether parents reinforce or compensate for child endowments. The authors employ birth weight as a proxy for endowments and estimate how the difference in birth weight across siblings impacts specific parental investments, including breastfeeding initiation and duration,...

Age at first mariage has risen dramatically since the mid-1960s among a wide spectrum of the U.S. population. Researchers have considered many possible explanations for this trend. Few, though, have asked why individuals should want to delay marriage in the first place. One possibility is that...

To fight wars in Iraq and Afghanistan, the Department of Defense has relied heavily on its reserve components. Among the hardships of activation is the possibility that reservists might suffer an earnings loss following their period of active-duty service due to difficulties reentering the...

This paper explores how observed and unobserved parental investments compensate for low birth weight. Controlling for family fixed effects, which encompass unobserved parental investment, we find birth weight positively correlates with math and reading scores and these estimates are considerably...

Numerous countries have enacted policies to promote the labor force participation of women around the years of childbearing, and unsurprisingly, many research articles have been devoted to evaluating their effectiveness. Perhaps more surprisingly, however, six such articles were submitted...

We analyze four methods to measure unexplained gaps in mean outcomes: three decompositions based on the seminal work of Oaxaca (1973) and Blinder (1973) and an approach involving a seemingly naive regression that includes a group indicator variable. Our analysis yields two principal findings. We...

Estimators that exploit an instrumental variable to correct for misclassification in a binary regressor typically assume that the misclassification rates are invariant across all values of the instrument. We show that this assumption is invalid in routine empirical settings. We derive a new...

The uncompensated wage elasticity of labor supply is a fundamental parameter in economics. Despite its central role, very few papers have studied directly how it has changed over time. We examine the evolution of the uncompensated labor supply elasticity using cross-sectional methods over the...
