Eligibility criteria for interventions can induce an Ashenfelter Dip, and subsequent mean-reversion may result in improvement over time even absent the intervention. We investigate these dynamics for a food-as-medicine program to treat diabetes, where eligibility required elevated hemoglobin A1c...

Studies of racial discrimination often condition on endogenous measures of race or on earlier decisions that might themselves be affected by discrimination. We develop quasi-experimental tools for estimating the impact of racial misclassification on measures of unwarranted disparity, and for...

Black children in the U.S. are twice as likely as white children to spend time in foster care. Such racial disparities raise concerns of discrimination, but might also reflect differences in the underlying need for intervention. This paper estimates unwarranted disparities (UDs)--racial...

Ten percent of Black children in the U.S. spend time in foster care--twice the rate of white children. We estimate unwarranted disparities in foster care placement decisions, adjusting for differences in the potential for future maltreatment by leveraging the quasi-random assignment of cases to...

Children spend years in foster care, and there are concerns that bureaucratic hurdles contribute to unnecessarily long stays. In a novel approach to policy making, the Chilean government randomized the introduction of a program aimed at reducing these delays in order to evaluate its effects on...
