Age-Dependent Labor Supply Reduction Near Retirement
Observational StudyReview
Income transfer programs affect demographic groups differently depending on their position in the life cycle [21, 22]. Identifying whether unearned income induces uniform work reductions or selectively triggers early retirement among older workers is essential for structuring pension and social security incentives [10, 23].
Picture this
Imagine runners in a marathon. Young runners who receive a boost of energy mid-race keep running with a slightly adjusted pace, but runners who are already within sight of the finish line use that extra energy to cross the line early and sit down on the bench immediately.
What the evidence says
Individuals aged 55 to 65 at the time of winning exhibit a significantly larger labor earnings reduction, with an additional MPE interaction coefficient of -0.167 (standard error 0.070), whereas individuals over 65 show no such additional reduction [4, 10, 23].
- Who was studied
- N = 194 human Massachusetts Megabucks lottery winners receiving $100,000 or less annually, segmented by age categories (under 55, 55–65, and over 65) [4, 5].
- How
- Interaction-effects linear regression of post-lottery Social Security earnings on yearly lottery prize crossed with demographic indicators for age groups 55–65 and over 65 [4, 5, 23].
What to do
1. Incorporate a 2.3-fold greater work reduction response among workers aged 55–65 compared to younger workers when modeling unearned income impact on retirement decisions.
From the source
"Individuals between 55 and 65 at the time of winning the lottery reduce their labor earnings significantly more than younger workers. Looking at the average post-lottery earnings, their MPE is lower by -0.167 (0.070)." [23]
