Supplemental plan offerings and retirement saving choices: an analysis of North Carolina school districts

Abstract

AbstractUnlike private sector employers, public school districts generally offer more than one type of supplemental retirement savings plan and allow multiple vendors to offer products. Using individual-level payroll data from over half of the public school districts in North Carolina coupled with data from an employer survey, this study examines how inter-district differences in supplemental plan administration are related to participation in these savings vehicles. We find wide variation in total participation rates and in 403(b) plan participation rates in particular, even among this population of public-sector workers with the same defined benefit pension plan, health plan, and retiree health coverage. Individual and district characteristics explain some, but not all, of the variation observed.
