A first stab at embedding the Diamond-Mortensen-Pissarides search model of unemployment into an equilibrium asset pricing framework.
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.
A comparison of new factor models (with Hou and Xue), 2014.
The Hou, Xue, and Zhang (2014) q-factor model is better than the Fama-French (2014) five-factor model on both economic and empirical grounds.
