We construct the large sample distributions of the OLS and GLS R^2’s of the second pass regression of the Fama-MacBeth (1973) two pass procedure when the observed proxy factors are minorly correlated with the true unobserved factors. This implies an unexplained factor structure in the first...

We propose the double robust Lagrange multiplier (DRLM) statistic for testing hypotheses specified on the minimizer of the population continuous updating objective function. The (bounding) χ2 limiting distribution of the DRLM statistic is robust to both misspecification and weak identification,...

In contrast with a large body of existing literature, Nekoei and Weber (2017, NW henceforth) find a positive effect of unemployment insurance on job quality. This comment shows that NW's finding is driven by unnecessarily large bandwidths used in their regression discontinuity analysis. When the...
