I am a financial economist who loves to solve real-world problems using models and data. 

A Stanford PhD, I am a professor at Copenhagen Business School, director of the BIGFI center, and a principal at AQR. I have served as Director of the American Finance Association, in the Liquidity Working Group meeting at the Federal Reserve Bank of New York to address liquidity issues, on the Economic Advisory Boards of NASDAQ and FTSE, and on several editorial boards, including the Journal of Finance and Quarterly Journal of Economics. 

My academic awards include the Bernácer Prize to the best E.U. economist under 40 years of age, the Banque de France-TSE Prize, the Stephen A. Ross Prize, Journal of Financial Economics Fama-DFA Prizes, Review of Financial Studies Michael Brennan Award, Journal of Finance DFA Prize and Brattle Prize, and FAJ Graham and Dodd Top Awards.

My research is highly used by academics, practitioners, regulators - e.g., the most cited paper in SEC regulation - and the Nobel Prize committee’s scientific background.  

Research Summary

One research agenda is liquidity risk, showing that a security’s required return is increased by market liquidity risk (as captured by the liquidity-adjusted capital asset pricing model) and funding liquidity risk (as captured by the margin CAPM), and how the interaction of market and funding liquidity can create liquidity spirals and systemic financial crisis. Indeed, when everyone runs for the exit, prices drop-and-rebound, margins increase, and risk management tightens. These liquidity risk models can help explain equity returns, option prices, bond yields, currency crashes, valuation in OTC search markets, the CDS-bond basis and other failures of the Law of One Price, the effect of unconventional monetary policy such as central banks’ lending facilities, low-beta returns, embedded leverage, predatory trading, shortselling, and the why markets are efficiently inefficient

Another research agenda explores the other factors that drive asset prices across markets and asset classes: betting against beta, quality minus junk, carry, size, value, momentum, time series momentum, and ESG. These factors help explain the returns of hedge funds, Warren Buffett, and global markets, and may be explained by social networks

A related effort studies the economics of capital markets and investment management, including sharpening the arithmetic of active management, and how to measure risk, use return signals, make optimization work, trade optimally accounting for transaction costs, and apply machine learning

I also show how ESG investing affects portfolio choice (ESG-efficient frontier), asset pricing (ESG-CAPM), corporate finance (ESG-Modigliani-Miller), and how green finance relates to carbon pricing

A final agenda studies whether finance research can be replicated, creating useful data sets for equities, corporate bonds, ESG measures, and beyond.
