Convergent trends in aggregate and firm volatility
Abstract
This article unearths the determinants of the volatility of aggregate and firm-level production proxied by output and turnover respectively. This article re-visits Comin and Mulani's Note on the diverging trends between aggregate and firm volatility. Similarly to their conclusions, I establish that firm volatility is not driven by a compositional bias in my sample and that it's entirely driven by its covariance element. Contrary to their conclusions, I find a convergence between firm-level and aggregate level volatility due in part to the 2007 financial crisis.
