October 2012Improving the Targeting of Treatment: Evidence from College Remediation
with Judith Scott-Clayton, Peter M. Crosta: w18457
At an annual cost of roughly $7 billion nationally, remedial coursework is one of the single largest interventions intended to improve outcomes for underprepared college students. But like a costly medical treatment with non-trivial side effects, the value of remediation overall depends upon whether those most likely to benefit can be identified in advance. Our analysis uses administrative data and a rich predictive model to examine the accuracy of remedial screening tests, either instead of or in addition to using high school transcript data to determine remedial assignment. We find that roughly one in four test-takers in math and one in three test-takers in English are severely mis-assigned under current test-based policies, with mis-assignments to remediation much more common than mis-a...
October 2010The Benefits of Breastfeeding Across the Early Years of Childhood
with Inas Rashad Kelly: w16496
The choice to breastfeed rather than formula-feed an infant as well as the duration of doing so has been scrutinized in more recent times. Yet, key identification issues remain to be resolved, including the array of possible child development benefits, the optimal intensity of breastfeeding versus formula- feeding, and the possibility of confounding with other inputs that promote child health. This study uses the Early Childhood Longitudinal Survey – Birth Cohort to explore the causal effect of breastfeeding on development across the early years of childhood. We examine a range of health, physical, and cognitive outcomes and relate these to a set of breastfeeding and formula-feeding intensities. Adjusting for a very extensive set of potential confounding factors that also promote child...
