RT Journal Article SR Electronic T1 Taken by Storm JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 1608 OP 1643 DO 10.3368/jhr.58.5.0819-10367R2 VO 58 IS 5 A1 Harris, Douglas N. A1 Larsen, Matthew F. YR 2023 UL http://jhr.uwpress.org/content/58/5/1608.abstract AB Hurricane Katrina was one of the nation’s worst natural disasters. It also triggered one of the nation’s most intense market-based school reforms, in which almost all traditional public schools were turned into charter schools. We study the effects of these combined events on students who attended New Orleans public schools before and after the storm. Using matched difference-in-differences, we find that student test scores, high school graduation, college attendance, and college graduation all rose sharply. Most racial and income gaps in outcomes declined. The school reforms appear to have been the main mechanism.
