RT Journal Article SR Electronic T1 Why Public Schools Lose Teachers JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 326 OP 354 DO 10.3368/jhr.XXXIX.2.326 VO XXXIX IS 2 A1 Hanushek, Eric A.

YR 2004 UL http://jhr.uwpress.org/content/XXXIX/2/326.abstract AB Many school districts experience difficulties attracting and retaining teachers, and the impending retirement of a substantial fraction of public school teachers raises the specter of severe shortages in some public schools. Schools in urban areas serving economically disadvantaged and minority students appear particularly vulnerable. This paper investigates those factors that affect the probabilities that teachers switch schools or exit the public schools entirely. The results indicate that teacher mobility is much more strongly related to characteristics of the students, particularly race and achievement, than to salary, although salary exerts a modest impact once compensating differentials are taken into account.
