The Well‑Tempered Retiree: Rational Choice in an Uncertain Retirement

Behavioral science has helped investors who are accumulating savings for retirement through well-known interventions such as auto-enrollment to a 401(k), auto-escalation, and other nudges. For those entering the decumulation stage of retirement, there has been less progress. There is little regulatory guidance, no single-product solution, and even practitioner rules of thumb are relatively scarce.

To address this gap, PIMCO conducted a proprietary research study last December in collaboration with The Harris Poll, looking to apply behavioral insights to this “decumulation dilemma.” Responses were collected and analyzed from 758 U.S. adults age 55 and older with over $500,000 in investable assets. Here we summarize the study’s results and what they mean for PIMCO’s approach to decumulation.

Confidence and overconfidence

Just over half of respondents (55%) either had no plan or planned to ignore their assets completely in their retirement. Despite this lack of planning, this group is equally, if not more confident than others. In fact, 83% of our respondents were highly confident about their ability to meet their retirement spending needs. Particularly concerning is that the investors who are both very confident and have no plan expect their assets to last the longest.

Investors may feel such confidence because they have successfully grown their investment portfolios as accumulators. But successful accumulation does not guarantee a successful decumulation. Regardless of one’s investing skill, in a portfolio that is being spent down, as in retirement, the assets are far more vulnerable: They are now exposed to the impact of both market shocks and spending. The portfolio is governed by new laws of gravity and exposed to greater levels of uncertainty, so it’s crucial to have “calibrated” confidence in one’s decumulation plan.
