Nudging Retirement Savings: A Field Experiment on Supplemental Plans
By Robert L. Clark, Robert G. Hammond, Melinda Sandler Morrill, Christelle Khalaf
Although supplemental saving plans can be an important part of an individual’s financial security in retirement, contribution rates remain low, particularly among those with lower salaries and less education. We report findings from a field experiment that distributed an informational nudge containing information on key aspects of the employer-provided supplemental saving plans of older public employees in North Carolina. Among workers participating in a supplemental plan, individuals who received an informational nudge increased their contributions in the months following the intervention relative to the control group. Moreover, those that received the nudge reported in a subsequent survey that they were more likely to have developed a retirement plan and report more confidence in their retirement preparedness. In contrast, individuals who were not enrolled in a retirement saving plan were not moved to begin contributing to a supplemental plan.
