This paper examines the evolution of risk in the U.S. financial sector using firm-level equity market data from 1975 to 2005. We find that over the past three decades, financial sector volatility has steadily increased, particularly from 1998 to 2002. Increased volatility, driven by common...

We propose a measure for systemic risk: CoVaR, the value at risk (VaR) of the financial system conditional on institutions being in distress. We define an institution's contribution to systemic risk as the difference between CoVaR conditional on the institution being in distress and CoVaR in the...

This paper examines the mechanism by which the incorporation of information into prices leads to cross-autocorrelations in stock returns. We present a simple model where trading on private information occurs first in the large stocks and is transmitted to small stocks with a lag. Such trading...

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...

We employ a model of leverage-induced explosive behavior in financial markets to develop a measure of financial market instability. Specifically, we derive a quantitative condition for how large levered investors can become relative to the whole market before the demand curve for securities...

The recent turmoil in global financial markets underscores the importance of the federal funds market as a means of distributing liquidity throughout the financial system and a tool for implementing monetary policy. In this paper, we explore the network topology of the federal funds market. We...

This paper explores the ability of theoretically based asset pricing models such as the CAPM and the consumption CAPM-referred to jointly as the (C)CAPM - to explain the cross-section of average stock returns. Unlike many previous empirical tests of the (C)CAPM, we specify the pricing kernel as...

This paper studies the role of detrended wealth in predicting stock returns. We call a transitory movement in wealth one that produces a deviation from its shared trend with consumption and labor income. Using U.S. quarterly stock market data, we find that these trend deviations in wealth are...

The consensus suggests that subdued nominal U.S. Treasury yields on balance since the onset of the global financial crisis primarily reflect exceptionally low, if not occasionally negative, term premiums as opposed to low anticipated short rates. Depressed term premiums plausibly owe to...

We identify and track over time the factors that make the financial system vulnerable to fire sales by constructing an index of aggregate vulnerability. The index starts increasing quickly in 2004, before most other major systemic risk measures, and triples by 2008. The fire-sale-specific...
