We summarize and evaluate Fannie Mae and Freddie Mac's credit risk transfer (CRT) programs, which have been used since 2013 to shift a portion of credit risk on more than $1.8 trillion of mortgages to private sector investors. We argue that the CRT programs have been successful in reducing the...

I develop a framework of the buildup and outbreak of financial crises in an asymmetric information setting. In equilibrium, two distinct economic states arise endogenously: "normal times", periods of modest investment, and "booms", periods of expansionary investment. Normal times occur when the...

In the conduct of monetary policy, there exists a risk-return trade-off between financial conditions and financial stability, which complements monetary policy's traditional trade-off between inflation and real activity. The trade-off exists even if monetary policy does not target financial...

We construct a new systemic risk measure that quantifies vulnerability to fire-sale spillovers using detailed regulatory balance sheet data for U.S. commercial banks and repo market data for broker-dealers. Even for moderate shocks in normal times, fire-sale externalities can be substantial. For...

We examine the properties of a method for fixing Libor rates that is based on transactions data and multi-day sampling windows. The use of a sampling window may mitigate problems caused by thin transaction volumes in unsecured wholesale term funding markets. Using two partial data sets of loan...

We study a dynamic model of collateralized lending under adverse selection in which the quality of collateral assets is endogenously determined by hidden effort. Complementarities in incentives lead to non-ergodic dynamics: Asset quality and output grow when asset quality is high, but stagnate...

This paper studies a recent tick size reduction in the U.S. Treasury securities market and identifies its effects on the market's liquidity and price efficiency. Employing difference-indifference regressions, we find that the bid-ask spread narrows significantly after the change, even for large...

Since the global financial crisis of 2007-09, policy makers and academics around the world have advocated the use of prudential tools for macroprudential purposes. This paper presents a macroprudential tabletop exercise that was aimed at confronting Federal Reserve Bank Presidents with a...

The London Interbank Offered Rate (LIBOR) is a widely used indicator of funding conditions in the interbank market. As of 2013, LIBOR underpins more than $300 trillion of financial contracts, including swaps and futures, in addition to trillions more in variable-rate mortgage and student loans....

In response to the sharp decline in prices of financial stocks in the fall of 2008, regulators in a number of countries banned short selling of particular stocks and industries. Evidence suggests that these bans did little to stop the slide in stock prices, but significantly increased costs of...
