Save More Later? The Effect of the Option to Choose Delayed Savings Rate Increases on Retirement Wealth
Delaying increased contributions to a retirement plan can actually boost retirement savings, but it all depends on how the delay is positioned.
The authors found that employees who are offered a convenient way to increase their contribution rates, either immediately or at a delayed time, are no more likely to accept an increase than employees offered only an immediate option. In fact, the former group tends to save less over the coming months, as the delayed option attracts some employees. However, when the delayed option is tied to a psychologically meaningful event, such as an employee’s next birthday, the negative effect of offering a delay is undone.
The researchers conducted a field experiment to test the efficacy of different ways to encourage retirement savings, sampling 8,251 employees at four U.S. universities. These employees were randomly placed into three groups. Each received a different mailing concerning their university’s retirement plan:
A no delay mailing encouraged employees to begin saving or saving more immediately.
A standard delay mailing gave employees the option to begin saving or saving more either immediately or after a time delay ranging from two to six months.
A framed delay mailing was identical to the standard delay mailing, except the time delay reference was replaced by a reference to a meaningful future event with the same time delay (e.g., “following your next birthday,” “following Thanksgiving”).
Finally, the researchers compared the actual contribution rates subsequently made by employees in each of the three groups.
