Empirical Asset Pricing, Credit Risk, Fixed Income, Liquidity Risk




Pricing of Sustainability-Linked Bonds (with Kristoffer Halskov and Arthur Krebbers), Journal of Financial Economics, forthcoming


Is Capital Structure Irrelevant with ESG investors? (with Lasse Heje Pedersen), Review of Financial Studies, forthcoming


Debt Dynamics and Credit Risk (with Stephen Schaefer), 2023, Journal of Financial Economics, 149, 497-535

     Firms with low equity returns take on more debt in the short run and less debt in the long run compared to firms with high equity returns. We incorporate these stochastic debt dynamics into structural models of credit risk, improving predictions of credit spreads.


Leveraged Buyouts and Bond Credit Spreads (with Yael Eisenthal-Berkovitz and Vikrant Vig), 2020, Journal of Financial Economics, 135, 577-601

     We show that the threat of a leveraged buyout has a substantial ex-ante impact on bond credit spreads, on average 18-21bps. The impact is stronger in expansion periods and for long-maturity bonds.


The Myth of The Credit Spread Puzzle (with Stephen Schaefer), 2018, Review of Financial Studies, 31, 2897-2942.

    We propose a statistically more precise approach for calibrating structural models of credit risk to historical default rates. Using this new approach we find that a standard structural model matches the level of investment grade bonds well. Model spreads for speculative bonds are too low, partly due to bond illiquidity.

Risk Premia and Volatilities in a Nonlinear Term Structure Model (with Christian Heyerdahl-Larsen and Philipp Illeditsch), 2018, Review of Finance, 22, 337-380

    A nonlinear term structure model with closed-form solutions. The model with only three latent factors captures variation in expected excess returns and yield volatilities and exhibits features consistent with unspanned stochastic volatility and unspanned risk premia. 

Outstanding Paper Award, Wharton’s Jacobs Levy Equity Management Center for Quantitative Research, 2014


The Value of Creditor Control in Corporate Bonds (with Edith Hotchkiss and Oğuzhan Karakaş), 2016, Journal of Financial Economics, 121, 1-27.

    A new way to measure the premium in corporate bond prices that is related to creditor control. The premium increases as firm credit quality decreases and around defaults, bankruptcies, and covenant violations.


Can Affine Models Match the Moments in Bond Yields?, 2016, Quarterly Journal of Finance, 2, 1650009

    For a wide range of risk premium specifications, there is no three-factor affine model that can simultaneously capture the predictability in bond excess returns and time variation in yield volatility.


Corporate Bond Liquidity Before and After the Onset of the Subprime Crisis (with Jens Dick-Nielsen and David Lando), 2012, Journal of Financial Economics, 103, 471-492.

   Illiquidity premia in US corporate bonds were large during the subprime crisis. Bonds become less liquid when financial distress hits a lead underwriter.

Monthly time series 2002:07-2009:12 of illiquidity of all US corporate bonds, industrial bonds, and financial bonds in the paper: Download. Updated data through 2023:06: Download. Our results are used in an Oliver Wyman study on the impact of the Volcker Rule on corporate bond liquidity. The study and our results are discussed in New York Times and Financial  Times.


The Same Bond at Different Prices: Identifying Search Frictions and Selling Pressures, 2012, Review of Financial Studies, 25, 1155-1206.

   A new way to measure selling pressures in over-the-counter markets. The evidence shows strong selling pressure in GM bonds in May 2005 and market-wide selling pressures in US corporate bonds during the subprime crisis. 


Systematic and Idiosyncratic Default Risk in Synthetic Credit Markets (with Mads Stenbo Nielsen), 2012, Journal of Financial Econometrics, 10, 292-324.

   How to estimate an intensity-based model for correlated defaults without the usual assumptions. The model matches the time-series variation of CDO tranche spreads well.

Decomposing Swap Spreads (with David Lando), 2008, Journal of Financial Economics, 88, 375-405.

   Use swap rates not Treasury yields as riskless rates. Hedging activity in the MBS market occasionally pushes swap rates down.
