Abstract: We resuscitated the mixed-frequency vector autoregression (MF-VAR) developed in Schorfheide and Song (2015) to generate macroeconomic forecasts for the United States during the COVID-19 pandemic in real time. The model combines 11 time series observed at two frequencies: quarterly and monthly. We deliberately did not modify the model specification in view of the COVID-19 outbreak, except for the exclusion of crisis observations from the estimation sample. We compare the MF-VAR forecasts to the median forecast from the Survey of Professional Forecasters (SPF). While the MF-VAR performed poorly during 2020:Q2, subsequent forecasts were at par with the SPF forecasts. We show that excluding a few months of extreme observations is a promising way of handling VAR estimation going forward, as an alternative of a sophisticated modeling of outliers.
