This paper examines the relationship between money market fund (MMF) risks and outcomes during crises, with a focus on the ABCP crisis in 2007 and the run on money funds in 2008. I analyze three broad types of MMF risks: portfolio risks arising from a fund's assets, investor risk reflecting the...

While the Dodd Frank Act (DFA) broadens the regulatory reach to reduce systemic risks to the U.S. financial system, it does not address some important risks that could migrate to or emanate from entities outside the federal safety net. At the same time, it limits the types of interventions by...

Early withdrawals from retirement accounts are a double-edged sword, because withdrawals reduce retirement resources, but they also allow individuals to smooth consumption when they experience demographic and economic shocks. Using tax data, we show that pre-retirement withdrawals increased...

Many U.S. corporations have frozen defined benefit (DB) pension plans, replacing new DB promises with contributions to defined contribution (DC) plans. We estimate expected DB accruals from the age-service and salary distributions of a large sample of U.S. corporate pension plans with more than...

I show how to use data from the Flow of Funds Accounts of the United States to estimate how much funding of nonfinancial businesses, households, and governments is provided by the domestic shadow banking system. I define the shadow banking system as the set of entities and activities that...

By stepping between bilateral counterparties, a central counterparty (CCP) transforms credit exposure. CCPs generally improve financial stability. Nevertheless, large CCPs are by nature concentrated and interconnected with major global banks. Moreover, although they mitigate credit risk, CCPs...

Even risky pension sponsors could offer essentially riskless pension promises by contributing a sufficient level of resources to their pension trust funds and by investing those resources in fixed-income securities designed to deliver their payoffs just as pension obligations are coming due....

Non-banks originated about half of all mortgages in 2016, and 75% of mortgages insured by the FHA or VA. Both shares are much higher than those observed at any point in the 2000s. We describe in this paper how non-bank mortgage companies are vulnerable to liquidity pressures in both their loan...

We examine the relation between changes in hedge fund stock holdings and measures of informational efficiency of equity prices derived from transactions data, and find that, on average, increased hedge fund ownership leads to significant improvements in the informational efficiency of equity...

We build a model of a financial intermediary, in the tradition of Diamond and Dybvig (1983), and show that allowing the intermediary to impose redemption fees or gates in a crisis -- a form of suspension of convertibility -- can lead to preemptive runs. In our model, a fraction of investors...
