When They're Sixty-Four: Peer Effects and the Timing of Retirement

This paper examines the effect of peers on an individual's likelihood of retirement using an administrative dataset of all retirement-eligible Los Angeles teachers for the years 1998-2001. We use two large unexpected pension reforms that differentially impacted financial incentives within and across schools to construct an instrument for others' retirement decisions. Controlling for individual and school characteristics, we find that the retirement of an additional teacher in the previous year at the same school increases a teacher's own likelihood of retirement by 1.5-2 percentage points. We then explore some possible mechanisms through which this effect operates.
