This study investigates appropriate estimation of estimator variability in the context of causal mediation analysis that employs propensity score-based weighting.
We develop and illustrate a general and innovative method for describing in detail the joint distribution of race and income among neighborhoods when only coarse income data are available.
Excess mortality in marginalized populations could be both a cause and an effect of political processes.
This report presents findings from a study of the WIA Adult and Dislocated Worker programs’ impacts on employment and earnings.

Two-Step Estimation in Ratio-of-Mediator-Probability Weighted Causal Mediation Analysis
Household Search or Individual Search: Does It Matter?
Most labor market search models ignore the fact that decisions are often made at the household level. We fill this gap by developing and estimating a household search model with on-the-job search and labor supply.
Firm-Level Early Intervention Incentives: Which Recent Employers of Disability Program Entrants Would Pay More? (Journal Article)
We simulate the effects of Social Security Disability Insurance (SSDI) reform proposals that make firms partially responsible for SSDI benefits paid to their former workers. The simulations suggest the proposals (if implemented) would greatly affect firms and the workforces that the firms employ. ...

In this article, we use data from the Current Population Survey (CPS) Veterans Supplement to estimate the impacts of the change in the VA PTSD rule on DC benefit receipt and self-reported cognitive disability.
Child Participation in Supplemental Security Income: Cross- and Within-State Determinants of Caseload Growth
This study is the first to exploit county variation for insights on the causes of child SSI caseloads. Health and economic variables explain a large share of the variation in receipt across counties. They explain 30 to 40% of the 2003 to 2008 caseload growth and about 25% of the 2008 to 2011 trend.
