A working paper from the National Bureau of Economic Research (NBER) says its study found retiree health coverage has its strongest effects at ages 62 and 63, resulting in a 3.7 percentage point (21.2%) increase in the probability of turnover at age 62 and a 5.1 percentage point (32.2%) increase in the probability of turnover at age 63. It has a more modest effect for individuals under the age of 62.
According to the paper, a more generous employer contribution of 50% or more raises turnover by one to three percentage points at ages 56-61, by 5.9 percentage points (33.7%) at age 62, and by 6.9 percentage points (43.7%) at age 63. Overall, an employer contribution of 50% or more reduces the total number of person-years worked between ages 56 and 64 by 9.6% relative to no coverage.
NBER researchers investigated the impact of retiree health insurance on early retirement using employee-level data from 64 diverse firms that are clients of Towers Watson.
