May 2019The Role of Neonatal Health in the Incidence of Childhood Disability
with David N. Figlio, Scott A. Imberman, Claudia Persico: w25828
We use linked birth and education records for all children born in Florida between 1992 and 2002 to assess the effects of neonatal health on the identification of childhood disabilities. We find that several measures of neonatal health are associated with disability incidence, although birthweight plays the most empirically relevant role. Using large samples of siblings and twins, we find that infant health influences multiple measures of disability and grade repetition in school. The association between birthweight and disability holds throughout the distribution of birthweight and across a range of socioeconomic characteristics, including maternal education and race.
School Segregation and Racial Gaps in Special Education Identification
with David N. Figlio, Scott A. Imberman, Claudia L. Persico: w25829
We use linked birth and education records from Florida to investigate how the identification of childhood disabilities varies by race and school racial composition. Using a series of decompositions, we find that black and Hispanic students are identified with disabilities at lower rates than are observationally similar white students. Black students are over-identified in schools with relatively small shares of minorities and substantially under-identified in schools with large minority shares. We find similar gradients among Hispanic students but opposite patterns among white students. We provide suggestive evidence that these findings are unlikely to stem from differential resource allocations, economic characteristics of students, or achievement differences. Instead, we argue that the r...
December 2002An Evaluation of Instrumental Variable Strategies for Estimating the Effects of Catholic Schools
with Joseph G. Altonji, Christopher R. Taber: w9358
Several previous studies have relied on religious affiliation and the proximity to Catholic schools as exogenous sources of variation for identifying the effect of Catholic schooling on a wide variety of outcomes. Using three separate approaches, we examine the validity of these instrumental variables. We find that none of the candidate instruments is a useful source of identification of the Catholic school effect, at least in currently available data sets

August 2000Selection on Observed and Unobserved Variables: Assessing the Effectiveness of Catholic Schools
with Joseph G. Altonji, Christopher R. Taber: w7831
We develop estimation methods that use the amount of selection on the observables in a model as a guide to the amount of selection on the unobservables. We show that if the observed variables are a random subset of a large number of factors that influence the endogenous variable and the outcome of interest, then the relationship between the index of observables that determines the endogenous variable and the index that determines the outcome will be the same as the relationship between the indices of unobservables that determine the two variables. In some circumstances this fact may be used to identify the effect of the endogenous variable. We also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that ...
