Library Fine Elimination — Return Rate Impact
Salt Lake City Public Library · Salt Lake City, USA · 2019
Summary
Counterintuitively, removing the financial penalty for late returns improved return rates, not worsened them. Patrons who had avoided the library to escape accumulated fines began returning, and the normalized relationship with the library reduced avoidance behavior. The finding challenges the assumption that penalties are necessary to secure compliance in public service contexts.
