“…By contrast, the small UCM which embeds the real house prices variable (model 6) shows very unreliable PC-inflation forecasts. Both models 5 and 6 support the evidence from the literature that suggests that FNOGs may differ from standard output gap estimates (Katay et al, 2020) and therefore might not be adequate gauges of inflationary pressures. The output gaps estimated with the larger UCM (models 6 and 7) prove to have good predictive inflation performance in comparison with the EC output gap, although the forecast errors are larger than for the output gaps of the small UCMs.…”
