Mandatory Retirement and Older Worker Employment Decisions: Evidence from a Matched Difference‐in‐Differences Estimator

Abstract

In 2008, the minimum age at which private‐sector workers in Taiwan could be forced by their employers to retire from their jobs was raised from 60 to 65 years. In this study, we evaluate the effects of the increase in the mandatory retirement age on the labour supply trend among the elderly using a nationally‐representative Taiwanese panel data set. Based upon the application of a combination of matching and difference‐in‐differences approaches, we find that postponing mandatory retirement has a significant effect, in terms of slowing down the withdrawal of the elderly from the labour force. Among elderly workers affected by the 2008 amendment, particularly those retiring from the public sector, the likelihood of re‐entering the labour market is found to be 3 to 4% higher than that for their counterparts who were not subject to such a constraint, a finding that clearly suggests that an increase in the mandatory retirement age helps to alleviate the problems associated with an aging population in countries where long‐term labour contracts are prevalent.
