Affirmative Action, Mismatch, and Economic Mobility after California’s Proposition 209
Zachary Bleemer
https://doi.org/10.1093/qje/qjab027
Computational Reproducibility: Access to the administrative data used in estimation is restricted due to federal law (FERPA) and privacy concerns. The author provided us the following information for obtaining the data: "For access to all University of California student records, you should contact each respective campus's Office of the Registrar (e.g. Walter Wong at UC Berkeley: oua2wong@berkeley.edu). For additional UC admissions records you should contact Institutional Research and Academic Planning at the UC Office of the President. For the National Student Clearinghouse records you should contact the NSC Research Center. For the California wage records, you should call the Labor Market Information Office at the CA Employment Development Department (916-262-2162)."
