Essays in the Economics of Education Copyright 2003 by Jesse Morris Rothstein 1 Abstract Essays in the Economics of Education by Jesse Morris Rothstein Doctor of Philosophy in Economics University of California, Berkeley Professor David Card, Chair Three essays consider implications of the strong association between student background characteristics and academic performance. Chapter One considers the incentives that school choice policies might create for the efficient management of schools. These incentives would be diluted if parents prefer schools with desirable peer groups to those with inferior peers but better policies and instruction. I model a “Tiebout choice” housing market in which schools differ in both peer group and effectiveness. If parental preferences depend primarily on school effectiveness, we should expect both that wealthy parents purchase houses near effective schools and that decentralization of educational governance facilitates this residential sorting. On the other hand, if the peer group dominates effectiveness in parental preferences, wealthy families will still cluster together in equilibrium but not necessarily at effective schools. I use a large sample of SAT-takers to examine the distribution of student outcomes across schools within metropolitan areas that differ in the structure of educational governance, and find little evidence that parents choose schools for characteristics other than peer groups. 2 This result suggests that competition may not induce improvements in educational productivity, and indeed I do not obtain Hoxby’s (2000a) claimed relationship between school decentralization and student performance. I address this discrepancy in Chapter Two. Using Hoxby’s own data and specification, as described in her published paper, I am unable to replicate her positive estimate, and I find several reasons for concern about the validity of her conclusions. Chapter Three considers the role of admissions tests in predictions of student collegiate performance. Traditional predictive validity studies suffer from two important shortcomings. First, they do not adequately account for issues of sample selection. Second, they ignore a wide class of student background variables that covary with both test scores and collegiate success. I propose an omitted variables estimator that is consistent under restrictive but sometimes plausible sample selection assumptions. Using this estimator and data from the University of California, I find that school-level demographic characteristics account for a large portion of the SAT’s apparent predictive power. This result casts doubt on the meritocratic foundations of exam-based admissions rules. i To Joanie, for everything. ii Contents List of Figures iv List of Tables v Preface vi Acknowledgements x 1.
