It Pays to Set the Menu: Mutual Fund Investment Options in 401(k) plans
This paper investigates whether mutual fund families acting as service providers in 401(k) plans display favoritism toward their own funds. Using a hand-collected dataset on retirement investment options, we show that poorly-performing funds are less likely to be removed from and more likely to be added to a 401(k) menu if they are affiliated with the plan trustee. 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 these trustee decisions are not ...

Complex mortgages
Complex mortgages became a popular borrowing instrument during the bullish housing market of the early 2000s but vanished rapidly during the subsequent downturn. These non-traditional loans (interest only, negative amortization, and teaser mortgages) enable households to postpone loan repayment compared to traditional mortgages and hence relax borrowing constraints. At the same time, they increase household leverage and heighten dependence on mortgage refinancing to escape changes in contract terms. We document that complex mortgages were chosen by prime borrowers with high income levels ...

The tradeoff between mortgage prepayments and tax-deferred retirement savings
We show that a significant number of households can perform a tax arbitrage by cutting back on their additional mortgage payments and increasing their contributions to tax- deferred accounts (TDA). Using data from the Survey of Consumer Finances, we show that about 38% of U.S. households that are accelerating their mortgage payments instead of saving in tax-deferred accounts are making the wrong choice. For these households, reallocating their savings can yield a mean benefit of 11 to 17 cents per dollar, depending on the choice of investment assets in the TDA. ; In the aggregate, these ...

Out of Sight No More? The Effect of Fee Disclosures on 401(k) Investment Allocations
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 ...
