Defining extreme liquidity as the tail of the illiquidity for all stocks, I propose a direct measure of market-wide extreme liquidity risk and find that it is priced cross-sectionally in the U.S. Between 1973 and 2014, the stocks with low extreme liquidity risk beta earned value-weighted average...

This paper investigates the asset pricing implications of investor disagreement about the likelihood of a systematic disaster. I specify a general equilibrium model with multiple trees and heterogeneous beliefs about rare event risk, to understand how risk-sharing mechanisms affect equity and...

I show that the composition of the financial sector has important asset pricing implications beyond the health of the aggregate financial sector. To assess the impact of massive balance sheet adjustments within the intermediary sector during the Great Recession and resolve conflicting asset...

This article proposes a general equilibrium model to explain the positive and sizable term premia implied by the data. The authors introduce a slow mean-reverting process of consumption growth and a segmented asset-market mechanism with heterogeneous trading technologies into an otherwise...

WThis doctoral thesis focuses on the effects of investor sentiment on asset pricing and the challenges of portfolio optimization under parameter uncertainty. The first essay "Sentiment risk premia in the cross-section of global equity" applies a recently developed sentiment proxy to the...

I propose a parsimonious econometric model for the stochastic process governing the evolution of per capita consumption and stock market dividend over time. The model features stochastic volatility of consumption and dividend growth rates, and time-varying likelihood of rare disasters. I embed...
