This working paper examines the potential changes in the disparities in employer-sponsored health insurance (ESI) and other benefits between low- and high-wage workers under health reform. The analysis suggests that potential changes firms make in compensation could decrease disparities between...

This working paper compares teacher/student links that have undergone a roster confirmation process—whereby teachers verify the subjects and students they taught—to teacher/student links from unconfirmed administrative data. Due to the departmentalization of instruction in math and...

This working paper used a randomized controlled trial to estimate the effectiveness of a U.S. government-funded farmer assistance program that trained more than 50,000 farmers throughout Armenia. Training did not increase household income or consumption, or affect mediating outcomes, such as...

This working paper uses urban school district data to investigate whether including track indicators or accounting for classroom characteristics in the value-added model is sufficient to eliminate potential bias resulting from the sorting of students into academic tracks. Accounting for two...

This working paper examines the sensitivity and precision of teacher value-added model (VAM) estimates obtained under model specifications that differ based on whether they include student-level background characteristics, peer-level background characteristics, and/or a double-lagged achievement...

To improve labor market outcomes of people with disabilities, Congress passed the Americans with Disabilities Act (ADA) in 1990. Immediately following enactment, the wages of people with disabilities decreased, but longer-term wage consequences have not been studied. Using data from the March...

This working paper used measurements of accelerometer-based and self-reported physical activity from the National Health and Nutrition Examination Survey 2003–2006 to develop and validate a set of models for predicting objective moderate to vigorous physical activity from self-report...

Ideally, nonexperimental methods that aim to replicate the results of rigorous randomized experiments focus on the intent to treat (ITT) experimental impact estimate, the most causally rigorous measure. This working paper develops a new replication approach that facilitates testing...

Nonexperimental methods, such as regression modeling or statistical matching, produce unbiased estimates if the underlying assumptions hold, but these assumptions are usually not testable. Most studies testing nonexperimental designs find that they fail to produce unbiased estimates, but these...

This working paper examines behavioral responses to an incentive program that offers high-performing teachers in 10 school districts across the country $20,000 to transfer into the district's hardest-to-staff schools. Specifically, the paper looks at high-performing teachers' willingness to...
