A peer-reviewed study published in the Review of Finance1 (Volume 30, Issue 5, 2026) delivers some of the most rigorous empirical evidence to date that financial advisors create genuine, measurable value when they proactively raise the subject of retirement savings. Authored by Daniel Hoechle, Stefan Ruenzi, Nic Schaub, and Markus Schmid, the paper draws on more than a decade of client-level data from a large Swiss retail bank spanning January 2011 to June 2021, covering over 20,000 clients, to make a compelling near-causal argument for the positive impact of advisor-initiated retirement-related contact.
The institutional backdrop is Switzerland's voluntary third-pillar pension system, where tax-exempt retirement accounts shield contributions from both income and wealth taxes. Despite an annual tax saving worth roughly 2 percent of income for a median Swiss earner, only 56 percent of employees contribute regularly. The researchers train their lens on this gap and whether an advisor's call can close it.
The Numbers Are Striking
The findings are direct and economically large. The unconditional probability that a client without a retirement account opens one in any given month is 0.3 percent. Following an advisor-initiated retirement-related contact, that probability jumps by 7.4 percentage points, a roughly 25-fold increase. For clients already holding retirement accounts, monthly net flows run 3.8 percentage points higher after advisory outreach, more than tripling the baseline of 1.7 percent. Daily-level analysis of fund trades confirms the direction of causality: purchases cluster on and immediately after the day of advisor contact, with no pre-trend in the days before.
The primary vehicle is retirement fund accounts rather than savings accounts, a distinction the authors acknowledge directly: advisors receive payments from fund providers, creating an institutional incentive to promote funds. Yet the authors argue the outcome is not compromised. "After-tax returns of advisor-induced retirement fund investments exceed returns of plausible alternative investments," they write. Even index funds and ETFs, the most competitive counterfactual, outperform retirement funds by only 64 basis points annually before tax, well below the 2 percent threshold needed to offset the tax advantage.
No Dark Side Found
A recurring concern in the financial advice literature is that advisors serve the institution at the client's expense. Hoechle and colleagues test this rigorously on multiple fronts. They find no evidence of clients redirecting savings from other accounts; contributions flow predominantly from checking accounts and external income, particularly bonus payments. Clients who contribute are not more likely to overdraw their checking accounts in the five subsequent years and are, in fact, significantly less likely to carry a loan. "We find no indication that advisor-induced contributions to retirement accounts lead to negative side effects, such as reductions in other savings or liquidity constraints," the authors state, adding that their evidence "points toward a bright side of financial advice."
The bank's profitability picture is addressed head-on. An additional CHF 100,000 in retirement fund balances increases average monthly client profit for the bank by CHF 25.3, equivalent to 47 percent of a typical monthly client profit. Commission and fee income drive the effect; retirement savings accounts neither profit nor cost the bank materially. The researchers describe this as a "win-win situation with rent-sharing between the bank and its clients."
The Access Gap Remains
The paper's most pressing concern is distributional. Advisors are systematically more likely to contact male, older, wealthier, and better-educated clients precisely the groups at lower risk of under-saving. Women, less wealthy individuals, and less-educated clients, those the literature consistently identifies as most vulnerable to retirement shortfalls, are least likely to receive a proactive call. When those clients are reached, their responsiveness at the extensive margin is somewhat higher, reinforcing what the researchers observe directly: the value of advice is highest where its delivery is lowest. "Advisors do not in particular target clients that are at a higher risk of under-saving for retirement," the authors note plainly.
5 Key Takeaways for Advisors and Investors
- Proactive outreach drives action. Advisor-initiated retirement conversations produce account openings at roughly 25 times the unconditional baseline rate.
- Tax advantages clear the performance hurdle. Even low-cost passive alternatives do not outperform retirement fund investments by enough to overcome the tax benefit.
- Retirement contributions are additive, not substitutive. The evidence shows new money, not reshuffled assets, funding these accounts.
- Liquidity risk is not a deterrent. Clients who contribute are less likely to carry debt in subsequent years, not more.
- The access gap is the field's unfinished work. The clients most vulnerable to under-saving remain the least likely to receive a retirement-related advisory contact.
