We disentangle the contribution of unobserved heterogeneity in idiosyncratic demand and productivity to firm growth. We use a model of monopolistic competition with Cobb-Douglas production and a dataset of Italian manufacturing firms containing unique information on firm-level prices to reach...

data support the model predictions.

We use matched employer-employees data for Italy to study the joint response of wages and employment to firm-level shocks. We construct a simple dynamic general equilibrium model of labor demand and supply that allows us to identify separately firing (or internal) and mobility (or external)...

We study the role of employment protection legislation (EPL) in determining firm size distribution. In many countries the provisions of EPL are more stringent for firms above certain size thresholds. We construct a simple model that shows that the smooth relation between size and growth...
