I apply the Qual VAR to forecasting the 2001 business recession out of sample and to analyzing the Romer and Romer (1989) narrative

Out of sample, the model predicts the timing of the 2001 recession quite well relative to the recession probabilities put forth at the time by professional forecasters. Qual VARs-which include information about the qualitative variable-can also enhance the quality of density forecasts of the other variables in the system. JEL classifications: F42, C25, C22
