"Measuring the Natural Output Level by DSGE Models: An Empirical Investigation for Switzerland"
Stefan Leist, Klaus Neusser
Zusammenfassung:The output gap plays an important role in the assessment and conduct of monetary policy. Most of the current literature, however, relies on filtering procedures which use ad hoc smoothness arguments for identification. Furthermore, they are subject to end-of-sample problems and do not provide estimates of the output gap based on economic theory. In contrast, our model-based approach relies on a precise definition of the natural level of output and consequently of the output gap. This paper provides, for the first time, an estimate of the output gap based on a DSGE small open economy model for Switzerland. We use Bayesian econometrics to derive an estimate of the output gap, which is then compared to some alternatives. Except for the last years, our measure of the output gap is close to zero most of the time. This suggests that price rigidities play a minor role in the propagation of the Swiss business cycle. We show that our estimate produces sensible and robust results which encourage further research.
