Job Loss, Retirement and the Mental Health of Older Americans Bidisha Mandal Brian Roe The Ohio State University Outline Motivation Literature Data Model Results Conclusion Future Research Motivation Increasing percentage of older individuals in the population. General decline in job security in U.S. labor market. Physical limitations, cognitive changes, bereavement are commonly associated with aging. Does work displacement cause additional distress? Are there any long-term effects? Job loss – skills may not be transferable, loss of income Retirement – lifestyle changes. Policy implication – increased private medical expenditure, increased public spending for government medical programs. Relevance Mental health affects social behavior, morale, as well as work productivity. Deteriorating mental health can manifest in weakened physical health and increase likelihood of suicide. Declines in the mental health may negatively influence the wellbeing of other household members. Older Americans may be less inclined to seek help for psychological problems (as compared to physical decrements). Job loss affects the quality of life Literature Retirement Kim and Moen (2002): 458 New York employees; 1994, 1996, 1998 waves of Cornell Retirement and Well-being study. Results: short-term boost in morale, and long-term increase in distress levels for men. Drentea (2002): 2 different cross-sectional national surveys Mixed results: lower sense of control, but lower anxiety levels among retirees. Midanik et al. (2005): 595 members of a health maintenance organization; short-term effect. Result: lower stress levels among retirees. No clear trend; No long-run national panel have been studied yet. Related Literature on Retirement Kerkhofs et al. (1999): health and retirement are endogenously related. Dwyer and Mitchell (1999), Disney et al. (2006): health problems influence retirement plans more strongly than economic variables. Involuntary Job Loss (business shut-down or lay-off) Gallo et al. (2000): 1992 and 1994 waves of Health and Retirement Study. Different methodology to handle endogeneity Reverse causality and unobserved heterogeneity OLS vs. HT/IV and 2SLS Alternative coding Framework Work displacement Involuntary job loss Retirement Easily adjusts to new lifestyle Reentry Unable to adjust to new lifestyle Retirement plans affected Reemployment Long spell or forced to retire CESD Score Mental health measure Developed by Radloff (1977) – short, self-reporting scale (20 items) for general population. HRS only includes 8 items – 6 negative and 2 positive binary indicators Negative items – felt depressed, everything an effort, sleep was restless, felt lonely, felt sad, could not get going Positive items – was happy, enjoyed life CESD = sum (negative items) – sum (positive items) Thus, higher score (0 to 8) means worse mental health. Both versions commonly used in other studies to measure distress and psychological well-being. Summary – CESD Score Reliability Cronbach’s alpha coefficient for 20 items = 0.85 Cronbach’s alpha coefficient for 8 items = 0.71 Mean change in CESD score among those who suffered involuntary job loss is 0.19 Mean change in CESD score among retirees is 0.17 Maximum increase in CESD score is reported between the first two waves (1992 to 1994), when job loss rates were high. CESD scores improve during latter waves for all. Coding Involuntary Job Loss and Retirement Unbalanced panel data 6 waves – 1992, 1994, 1996, 1998, 2000 and 2002 N=7,780 (all those employed in 1992, 51-61 years old) Coding Survey does not ask R if suffered involuntary job-loss, but reason for unemployment. Involuntary job loss Retirement (voluntary) If R reports business closure or layoff, and started looking for job immediately. If R accepts early retirement incentives, and does not look for job immediately. These individuals also call themselves – ‘self-retired’. Plus, those who report retirement as labor market status.

(2000) use data from 1992 and 1994 HRS. Sample selection is sufficient to take care of latent effects – exclude retirees, self-employed individuals, disabled, and those who left their jobs for reasons other than plant closure and lay-off. Involuntary job loss – plant closure and lay-off Method – OLS regression. Replicate their coding and methodology, and obtain estimate of involuntary exit similar to theirs.
