Key Findings:
  • Low-cost, behaviorally informed emails increased the number of U.S. Department of Labor (DOL) employees saving at least 5 percent of their salary by 7.5 percentage points.
  • Emails raised the overall contribution rate by up to 0.4 percentage points, or approximately $11,500, over an employee’s lifetime.
  • Emails were not effective in causing non-contributors to start contributing a percentage of their salary to the Thrift Savings Plan.
This project brief summarizes findings from Mathematica's behavioral insights study conducted for the U.S. Department of Labor's Employee Benefits Security Administration (EBSA).
