The Hou, Xue, and Zhang (2015) q-factor model outperforms the Fama-French (2015) five-factor model on both conceptual and empirical grounds.
The CAPM strikes back? An investment model with disasters (with Bai, Hou, and Kung), 2015. Slides
An investment model with rare disasters reproduces the failure of the CAPM in explaining the value premium in finite samples in which disasters are not materialized, as well as its relative success in samples in which disasters are materialized.
The textbook Diamond-Mortensen-Pissarides model of equilibrium unemployment, once solved accurately with a globally nonlinear algorithm, gives rise endogenously to rare disasters.
A search and matching model with credible bargaining, when calibrated to the mean and volatility of unemployment in the postwar sample, can potentially explain the unemployment crisis in the Great Depression.
Solving the DMP model accurately (with Petrosky-Nadeau), 2014.
An accurate global algorithm is critical for solving the search model of unemployment; loglinearization understates the volatility of unemployment but overstates the unemployment-vacancy correlation.
