We explore the pricing of variance risk by decomposing stocks' total variance into systematicand idiosyncratic return variances. While systematic variance risk exhibits a negative priceof risk, common shocks to the variances of idiosyncratic returns carry a large positive riskpremium. This...

This paper examines the role of bond ratings and the effects of rating-based regulations in thecorporate bond market. Exploiting an unanticipated mechanical change in how the benchmarkLehman bond indices are constructed in 2005, we show that rating-induced market segmentationof the bond market...

This paper documents a new channel for rating-based bond market segmentation which, in contrast to prior research, is based on non-regulatory asset management practices. A 2005 Lehman Brothers index redefinition provides a quasi-natural experiment in which a number of previously high-yield...

We use a dynamic model of cash management in which firms face competitive pressure to show that competition increases corporate cash holdings as well as the frequency and size of equity issues. In our model, these effects are driven by small, financially constrained firms, in contrast with the...

We model the joint effects of debt maturity and cash holdings on default risk. When firms have short-term debt outstanding, negative cash flow shocks lead to a drop in liquid reserves and may cause firms to suffer losses when rolling over their debt, due to weaker fundamentals. This mechanism...

We challenge the view that short-term debt curbs moral hazard and analytically demonstrate that, in a world with financing frictions and fair debt pricing, short-term debt increases incentives for risk-taking. To do so, we develop a model in which firms are financed with equity and short-term...
