The influence of late retirement on health outcomes among older adults in the policy context of delayed retirement initiative: an empirical attempt of clarifying identification bias

Abstract

Background The deepening population aging is urging policy makers to launch delayed retirement initiative, when the society is faced with unprecedented challenges of shrinking labor supply, heavier pension burdens and slowing economic growth. However, the health outcomes of late retirees receive scarce attention due to the intrinsic identification difficulties (i.e., (1) self-selection bias – older adults with predetermined ill-health are less likely to delay retirement. (2) there can be situations where the status of late retirement has terminated at the time of interview, although he/she has ever delayed retirement). To fill in this research gap, this study examines the effect of late retirement on the difficulty in physical functioning and problems of cognitive status among older adults. Method Using the data from China Health and Retirement Longitudinal Study (CHARLS-2015 harmonized, and CHARLS-2018), this study investigates the influence of late retirement (year 2015) on the difficulty in physical functioning and problems of cognitive status (year 2018) among older adults. A series of robustness checks are also conducted. Results Empirical results show that late retirement is associated with better physical functioning and cognitive status. The influence remains robust after considering potential self-selection bias and the sensitivity of including/excluding older adults who have past late retirement experience but have no longer been late retirees at the time of survey. Conclusion This study suggests that older adults might benefit from the engagement in late careers in their physical and cognitive functioning.

Subjective Aging Difficulties among Older Adults with Subjective Cognitive Decline

“…Psychosocial supports, including teaching skills to improve mood, changing negative thinking patterns, and increasing engagement in enjoyable activities, have decreased depressive symptoms in older adults in general (Cuijpers et al, 2011). Similarly, younger-old adults in employment or voluntary community work may have greater daily function competences and coping with SCD in IADLs (Li et al, 2021), requiring consideration in the design of SCD in IADLs interventions with them.…”

How Late-Life Working Affects Depression Among Retirement-Aged Workers? An Examination of the Influence Paths of Job-Related (Non–Job-Related) Physical Activity and Social Contact

“…3 Participation in late careers can increase self-efficacy and maintain cognitive functioning among retirement-aged workers. 4 Prior studies show that work participation can help ease depression and anxiety among retirement-aged workers, 5 as it provides a unique environment that keeps older adults mentally, physically, and socially active. 6 Retirees are found to have more mental health problems than those who stay in the labor market.…”

Late career participation of late retirees in the age of the silver tsunami: understanding the influencing mechanism of health status and employment-based health insurance participation

“…As physical executive function and cognitive function (e.g. working memory, abstract thinking and verbal communication) decline with age [ 27 ], the odds of difficulty in IADLs may increase among older workers [ 28 ]. Difficulty in IADLs can negatively affect older workers’ working ability (e.g.…”
