In Simple Words
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.
Lottery winners receiving at most $100,000 a year
- Under 55 at winning
- Reference earnings response
- Age 55 to 65 at winning
- 16.7 cents larger drop per prize dollar
Estimated age interaction for average earnings in years one to six; standard error 7.0 cents per prize dollar. Over-65 group omitted.

Income transfer programs affect demographic groups differently depending on their position in the life cycle. 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.
Participants
N = 194 human Massachusetts Megabucks lottery winners receiving $100,000 or less annually, segmented by age categories (under 55, 55–65, and over 65).
Study Design
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.
Results
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.
Takeaway
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.
