Publication Bias and the Cross-Section of Stock Returns with Andrew Y. Chen
Review of Asset Pricing Studies, 2020, vol 10(2), pp. 249–289
In a sample of around 150 replicated cross-sectional stock return predictors, publication bias adjusted returns are only 13% smaller than in-sample returns. Among predictors that can survive journal review, a low t-stat hurdle of 1.8 controls for multiple testing using statistics recommended by Harvey, Liu, and Zhu (2015)

Journal of Financial Economics, 2020, vol 135(3), pp. 678-703
Employment in counties with stronger presence of banks more affected by QE grew more than employment in counties with weaker presence of such banks. This can be traced to credit supply effects in the mortgage and commercial & industrial lending markets.

The “Privatization” of Municipal Debt
with Ivan Ivanov
Municipal goverments have been increasing their reliance on private bank loans with relatively little disclosure requirements. These loans have high effective debt priority relative to municipal bonds and they are more likely to be used by local governments that experienced adverse income shocks.

Bottom-up leading macroeconomic indicators: An application to non-financial corporate defaults using machine learning
with Tyler Pike and Horacio Sapriza
We construct an indicator of non-financial corporate health aggregating default predictions from different machine learning models. The indicator predicts real economic outcomes such as GDP growth and employment for up to 8 quarters ahead.

Tree-based conditional portfolio sorts: The relation between past and future stock returns
with Benjamin Moritz
We introduce a regression tree approach to predict cross-sectional stock returns from many predictors. A trading strategy based on our method has an information ratio about twice as high as the information ratio from a standard Fama-MacBeth approach.
