What should applied macroeconomists know about local projection (LP) and vector autoregression (VAR) impulse response estimators? The two methods share the same estimand, but in fi…
Double Robustness of Local Projections and Some Unpleasant VARithmetic
José Luis Montiel Olea, Mikkel Plagborg-Møller, Eric Qian +1
We consider impulse response inference in a locally misspecified vector autoregression (VAR) model. The conventional local projection (LP) confidence interval has correct coverage…
Heterogeneity-robust granular instruments
Eric Qian
Granular instrumental variables (GIV) has experienced sharp growth in empirical macro-finance. The methodology's rise showcases granularity's potential for identification across ma…
