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...

We exploit time variation in the degree of development of local credit markets and matched employer-employee data to assess the role of the firm as an internal credit market. In less developed local credit markets firms can offer a flatter wage-tenure profile than firms in more developed credit...

We present a model in which the owner of the firm enjoys a private benefit from developing a personal relationship with the executives. This may lead the owner to retain a senior executive in office even though a more productive replacement is available. The model shows that the private returns...

We use linked employer-employee data from Italy to explore the relationship between exports and wages. Our empirical strategy exploits the 1992 devaluation of the Italian Lira, which represented a large and unforeseen shock to Italian firms’ incentives to export. The results indicate that the...

We contrast two potential explanations of the substantial differences in entrepreneurial activity observed across geographical areas - entry costs and external effects. We extend the Lucas model of entrepreneurship to allow for heterogeneous entry costs and for externalities that shift the...

The 1998 reform of the Italian retail trade sector delegated the regulation of entry of large stores to the regional governments. We use the local variation in regulation to determine the effects of entry barriers on sectoral performance. We address the endogeneity of entry barriers through...

We study the relation between workers’ skill dispersion and firm productivity using a unique dataset of Italian manufacturing firms from the early eighties to the late nineties with individual records on all their workers. Our measure of skill is the individual worker’s effect obtained as a...
