A mixed-frequency semi-structural model is used for estimating unobservable quantities such as the output gap, the Phillips curve and the NAIRU in real time. We consider two specifications: in one the output gap is observed as the official CBO measure, in the other is unobserved and derived via minimal theory-based restrictions. We find that the CBO model implies a smoother trend output but the second model better captures the business cycle dynamics of nominal and real variables. The methodology offers both a framework for evaluating official estimates of unobserved quantities of economic interest and tracking them in real time.
