Private Debt versus Bank Debt in Corporate Borrowing, 2026. With Sharjil Haque and Simon Mayer
Forthcoming Journal of Financial Economics
Using administrative bank loan-level data matched to private debt deals, we study the interaction between private and bank debt for a large segment of dual borrowers. These firms use private debt for investment and bank credit lines for liquidity insurance. Private debt carries higher spreads and commonly features flexible, equity-like terms that are associated with greater reliance on bank credit lines. Relative to bank-only borrowers, dual borrowers obtain more and larger credit lines and draw them more intensively following liquidity shocks. Our findings suggest that private debt substitutes for bank term loans but complements banks’ provision of liquidity through credit lines.
Mutual Fund Revenue Sharing in 401(k) Plans, 2025. With Clemens Sialm and Veronika Pool.
Management Science
Recordkeepers in DC pension plans are often paid indirectly in the form of revenue sharing from third-party funds on the menu. We show that these arrangements affect the investment menu of 401(k) plans. Revenue-sharing funds are more likely to be added to the menu and are less likely to be deleted. Overall, revenue-sharing plans are more expensive as higher expense ratios are not offset by lower direct fees or by superior performance. Rebates increase with the market power of the recordkeeper suggesting that third-party funds may revenue share to gain access to retirement assets.
3. Out of sight no more? The effect of fee disclosure on 401(k) Investment allocations, 2021. With Mathias Kronlund, Veronika Pool and Clemens Sialm.
Journal of Financial Economics
We examine the effects of a 2012 regulatory reform that mandated fee and performance disclosures for the investment options in 401(k) plans. We show that participants became significantly more attentive to expense ratios and short-term performance after the reform. The disclosure effects are stronger among plans with large average contributions per participant and weaker for plans with many investment options. Additionally, these results are not driven by secular changes in investor behavior or sponsor-initiated changes to the investment menus. Our findings suggest that providing salient fee and performance information can mitigate participants’ inertia in retirement plans.
4 . Cost savings and the freezing of corporate pension plans, 2020. With Joshua Rauh and Steve Zeldes
Journal of Public Economics
Companies that freeze defined benefit pension plans save the equivalent of 13.5 percent of the long-horizon payroll of current employees. Furthermore, firms with higher prospective accruals are more likely to freeze their plans. Cost savings would not be possible in a benchmark model in which i) all workers receive compensation equal to their marginal product and ii) workers value equally all identical-cost forms of pension benefits. We find evidence consistent both with firms’ reneging on implicit contracts to provide workers with high pension accruals later in their careers and with shifts in employee valuation of different forms of retirement benefits.
5 . Pay me now (or later): Bonus boosts before pension freezes and executive departures, 2018. With Yupeng Wang, Kangzhen Xie and Jun Yang
Journal of Financial Economics
Large U.S. firms modify top executives’ compensation before pension-related events. Top executives receive one-time increases in pensionable earnings through higher annual bonuses one year before a plan freeze and one year before retirement. Firms also boost pension payouts by lowering plan discount rates when top executives are eligible to retire with lump-sum benefit distributions. Increases in executive pensions do not appear to be an attempt to improve managerial effort or retention, and are more likely to occur at firms with poor corporate governance. These findings suggest that in some circumstances managers are able to extract rents through their pension plans.
6. It Pays to Set the Menu: Mutual Fund Investment Options in 401(K) Plans, 2016. With Veronika Pool and Clemens Sialm
Journal of Finance
This paper investigates whether mutual fund families acting as service providers in 401(k) plans display favoritism toward their own affiliated funds. Using a hand-collected dataset on the menu of investment options offered to plan participants, we show that fund deletions and additions are less sensitive to prior performance for affiliated than for unaffiliated funds. We find no evidence that plan participants undo this affiliation bias through their investment choices. Finally, the subsequent performance of poorly-performing affiliated funds indicates that this favoritism is not information driven.
7. Financial Misrepresentation and its Impact on Rivals , 2012. With Eitan Goldman and Urs Peyer
Financial Management
Firms targeted by Securities and Exchange Commission enforcement actions for fraudulent financial misrepresentation, on average, experience a significant drop in shareholder value. This paper highlights the additional impact of such enforcement actions on the shareholders of rival firms. Consistent with the importance of the industry competition effect we find that rivals in less competitive industries benefit from the event. However, in competitive industries, the information spillover effect dominates the competition effect, resulting in negative returns to rival shareholders following the event. We find that the spillover effect increases in importance with the severity of the accusation of financial misrepresentation. We also find that the information spillover effect is more important for opaque rivals and for rivals that had positive stock price reactions to past positive earnings surprises of the accused firm. Results from this paper shed light on the differential impact of financial misrepresentation on rival firms.
8. How do pension plans affect corporate capital structure decisions?, 2010. Joint with Anil Shivdasani
The Review of Financial Studies
This paper examines the capital structure implications of defined benefit corporate pension plans. The magnitude of the liabilities arising from these pension plans is substantial. We show that leverage ratios for firms with pension plans are about 35% higher when pension assets and liabilities are incorporated into the capital structure. We estimate that the tax shields from pension contributions are about a third of those from interest payments. Pension contributions have a modest effect in lowering firms’ marginal corporate tax rates. Once pensions are considered, firms are less conservative in their choice of leverage than has been previously thought. We show that firms incorporate the magnitude of their pension assets and liabilities into their capital structure decisions.
9. Why are Firms in the United States Abandoning Defined Benefit Pension Plans?, 2009. With Joshua Rauh
Rotman International Journal of Pension Management
This article investigates why many publicly listed corporations in the United States reduced or terminated the availability of defined benefit plans during 1998-2007. Firms limited benefit accruals in a variety of ways, including standard and distress terminations, freezes, and conversions to cash balance plans. While the decision to change the pension plan is related to the financial health of the sponsor, total benefit costs do not immediately decline when pension plans are frozen, as contributions to defined contribution plans increase almost immediately. However, we find that ‘freeze firms’ experience significant reductions in their projected benefit obligations of their defined benefit plans. This implies that most of the cost savings are generated from avoiding defined benefit plan accruals relating to future salary increases for current plan participants.

Asset Reclassification and Mutual Fund Flows , 2026, With Nicolas Bollen, Veronika Krepely Pool, Irina and Alexey Vasilenko
This paper documents substantial asset `reclassification' in the U.S. mutual fund industry: fund assets are moved into twin separate accounts and collective trusts sharing the same strategy and portfolio team. In 2021, transfers between mutual funds and their twin vehicles exceeded $550 billion. These reclassifications involve no investor flows, yet they distort measured fund flows, creating a non-classical measurement error that biases coefficient estimates in flow-based regressions. Adjusting for reclassification changes the estimates of central relationships in the mutual fund literature, such as flow-performance sensitivity, flow sensitivity to the Morningstar rating, and smart- and dumb-money tests.
Choosing Pension Fund Investment Consultants, 2026. With Aleksandar Andonov and Matteo Bonetti
Pension funds rely on the advisory services of investment consultants for asset allocation decisions, manager selection, and performance benchmarking. Pension funds have increased the number of investment consultants over time, particularly in alternative assets, such as real assets, private equity, and hedge funds. We examine the selection and termination of investment consultants by U.S. public pension funds between 2001 and 2020. We find that the replacement of general consultants is strongly related to prior returns while the hiring of specialized consultants strongly depends on target allocations gaps and board composition. General consultants replacements are followed by changes in target allocations but no significant improvements in pension fund performance. Specialized consultants allow pension funds to access and scale up investments in private markets as pension funds are more likely to invest in private funds from the consultants' networks. However, relaxing pension fund rationed access to private markets does not translate into access into better performing funds.
The Geography of Savings Opportunities in Retirement Plans, 2026. With Veronika Pool, Clemens Sialm and Hanjiang Zhang
We study mutual fund fees in 401(k) plans from 2011 to 2021 to examine disparities in retirement savings opportunities. We find that despite an increase in ERISA-based lawsuits and regulatory attention, workers face significant inequalities across geographies. We also show that the savings gap is further exacerbated by the asset allocation decisions of participants in higher-fee plans and the lower performance of the investment options available on these menus.
