We study the performance and behavior of Value at Risk (VaR) measures used by a number of large banks during and before the financial crisis. Alternative benchmark VaR measures, including GARCH-based measures, are also estimated directly from the banks' trading revenues and help to explain the...

We conduct an empirical analysis of the Federal Reserve's large-scale asset purchases (LSAPs) on MBS yields and mortgage rates. The Federal Reserve's accumulation of MBS and Treasury securities lowered MBS yields and mortgage rates by more than what would have been suggested by changes in market...

This paper examines whether banks strategically incorporate their competitors' liquidity mismatch policies when determining their own and how these collective decisions impact financial sector stability. Using a novel identification strategy exploiting the presence of partially overlapping peer...

How should regulators design effective emergency lending facilities to mitigate stigma during a financial crisis? I explore this question using data from an unexpected disclosure of partial lists of banks that secretly borrowed from the lender of last resort during the Great Depression. I find...

The concentration of risk within financial system is considered to be a source of systemic instability. We propose a theory to explain the structure of the financial system and show how it alters the risk taking incentives of financial institutions. We build a model of portfolio choice and...

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...

What are the consequences of a potential fire sale stemming from the exemption of repurchase agreements (repos) from automatic stay? This paper shows that repo's exemption from stay alters firms' financing and investment decisions ex ante. Specifically, a stay exemption changes firms' investment...

During the 2007-09 financial crisis, there were severe reductions in the liquidity of financial markets, runs on the shadow banking system, and destabilizing defaults and near-defaults of major financial institutions. In response, the Federal Reserve, in its role as lender of last resort (LOLR),...

I test and find supporting evidence for the precautionary motive hypothesis of liquidity hoarding for U.S. commercial banks during the recent financial crisis. I find that banks held more liquid assets in anticipation of future losses from securities write-downs. Exposure to securities losses in...
