Using the approach suggested by Gabaix (Econometrica 2011) this paper demonstrates that idiosyncratic shocks in the largest firms are important for an understanding of aggregate volatility in German manufacturing industries. The implications of this finding for theoretical and empirical research...

In this work we study the granular origins of business cycles and their possible underlying drivers. As shown by Gabaix (2011), the skewed nature of firm size distributions implies that idiosyncratic (and independent) firm-level shocks may account for a significant portion of aggregate...

The extraordinary events surrounding the Great Recession have cast a considerable doubt on the traditional sources of macroeconomic instability. In their place, economists have singled out financial and uncertainty shocks as potentially important drivers of economic fluctuations. Empirically...

In this paper, we analyse the effects of the stimulus packages adopted by the German government during the Great Recession. We employ a standard mediumscale dynamic stochastic general equilibrium (DSGE) model extended by nonoptimising households and a detailed fiscal sector. In particular, the...

To analyze the international transmission of business cycle fluctuations, we propose a new multilevel dynamic factor model with a block structure that (i) does not restrict the factors to being orthogonal and (ii) mixes data sampled at quarterly and monthly frequencies. By means of Monte Carlo...

This paper studies financial market disturbances as sources of investment fluctuations in Finland during 1995–2008. We construct a DSGE model of the Finnish economy that incorporates two domestic financial market shocks and financial frictions in the form of a BGG financial accelerator. We...
