Abstract

This paper employs a calibrated new-Keynesian DSGE model to assess the relative importance of two different, potentially important drivers of the Great Moderation in the U.S., namely 'good policy' vs. 'good luck'. The calibrated model is capable to replicate the actual standard deviations of inflation and output. Factual and counterfactual simulations are run in order to gauge the relative importance of the systematic monetary policy vs. the stochastic shocks hitting the economic system in shaping some macroeconomic volatilities. Importantly, under the bad policy scenario sunspots may influence the equilibrium values of the macroeconomic variables of interest, and distortions in the transmission mechanism going from the structural shocks to the variables of interest are allowed for. Our findings support the relevance of both drivers in causing inflation volatility. By contrast, output volatility can hardly be explained by a monetary policy switch like the one occurred in the U.S. at the end of the '70s.
