RT Journal Article SR Electronic T1 Do Tenured and Tenure-Track Faculty Matter? JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 647 OP 659 DO 10.3368/jhr.XL.3.647 VO XL IS 3 A1 Ehrenberg, Ronald G. A1 Zhang, Liang YR 2005 UL http://jhr.uwpress.org/content/XL/3/647.abstract AB During the last two decades, there has been a significant growth in the share of faculty members at American colleges and universities that are employed in part-time or full-time nontenure-track positions. Our study is the first to address whether the increased usage of such faculty adversely affects undergraduate students' graduation rates. Using institutional level panel data from the College Board and other sources, our econometric analyses suggest that the increased usage of these faculty types does adversely affect graduation rates at four-year colleges, with the largest impact on students being felt at the public master's level institutions.
