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 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...
