One of the most important trends in modern macroeconomics is the shift from small firms to large firms. At the same time, financial markets have been transformed by advances in information technology. We explore the hypothesis that the use of big data in financial markets has lowered the cost of...

This paper studies U.S. banks' exposure to interest rate and credit risk. We exploit the factor structure in interest rates to represent many bank positions in terms of simple factor portfolios. This approach delivers time varying measures of exposure that are comparable across banks as well as...

Among stock market entrants, more firms over time are R&D–intensive with initially lower profitability but higher growth potential. This sample-selection effect determines the secular trend in U.S. public firms' cash holdings. A stylized firm industry model allows us to analyze two competing...

We propose a dynamic bank theory with a delayed loss recognition mechanism and a regulatory capital constraint at its core. The estimated model matches four facts about banks' Tobin's Q that summarize bank leverage dynamics. (1) Book and market equity values diverge, especially during crises;...

This paper develops a parsimonious static model for characterizing financing terms in collateralized lending markets. We characterize the systematic risk exposures for a variety of securities and develop a simple indifference-pricing framework to value the systematic crash risk exposure of the...

We document that the risks and pre-fee returns of broad hedge fund indices can be accurately matched with simple equity index put writing strategies, which provide monthly liquidity and complete transparency over their state-contingent payoff profiles. This nonlinear risk exposure combines with...

This paper examines asset fire sales, and institutional price pressure more generally, in equity markets, using market prices of mutual fund transactions caused by capital flows from 1980 to 2003. Funds experiencing large outflows (inflows) tend to decrease (increase) existing positions, which...
