Testing the Effectiveness of a Future Selves Intervention for Increasing Retirement Saving: Evidence from a Field Experiment in Mexico
Abstract One psychological barrier impeding saving behavior is the inability to fully empathize with one’s future self. Future self interventions have improved savings by helping people overcome this obstacle. Despite the promise of such interventions, previous research has focused predominantly on hypothetical contexts and western settings where the target sample has been predominantly undergraduate. Do interventions that encourage people to more concretely consider their future selves during retirement still have a positive effect on behavior in consequential, real-world savings decisions? Using a field experiment in Mexico (N = 7,603), where less than 1% make a voluntary savings contribution annually, we developed a low-cost, easy-to-implement intervention to test whether concrete thinking about one’s future life improves recurring retirement savings signups relative to a status quo, control group. We find that future self decision aids significantly improved the likelihood of signing up for an automatic recurring savings plan by nearly four times compared to the control.
