On the Sources of Business Cycles: Implications for DSGE Models
 Andrle, Michal ; Brůha, Jan ; Solmaz, Serhat
What are the drivers of business cycle fluctuations? And how many are there? By documenting strong and predictable co-movement of real variables during the business cycle in a sample of advanced economies, we argue that most business cycle fluctuations are driven by one major factor. The positive co-movement of real output and inflation convincingly argues for a demand story. This feature—robust across time and space—provides a simple smell test for structural macroeconomic models. We propose a simple statistic that can compare data and models. Based on this statistic, we show that the recent vintage of structural economic models has difficulties replicating the stylized facts we document.

Inflation and Output Comovement in the Euro Area: Love at Second Sight?
 Andrle, Michal ; Brůha, Jan ; Solmaz, Serhat
This paper discusses comovement between inflation and output in the euro area. The strength of the comovement may not be apparent at first sight, but is clear at business cycle frequencies. We propose a new estimation approach to trimmed mean inflation, determining jointly the upper and lower quantiles to be trimmed, as well as the frequency bandwidth of real output that best aligns inflation with the output cycle. Our results suggest that at business cycle frequency, the comovement of output and core inflation is high and stable, and that inflation lags behind the output cycle with roughly half of its variance. The strong relationship between output and inflation hints at the importance of demand shocks for the euro area business cycle.
