When economic activity is concentrated over space or over time, it is more efficient. Most production occurs in geographic hot spots, and most production occurs between 9 and 12 in the morning and 1 to 5 in the afternoon on weekdays. The thick-market efficiencies that encourage the concentration...

The paper investigates whether firms have better access to bank credit in areas with a larger degree of urbanization. It uses bank-firm data drawn from the Credit Register maintained at the Bank of Italy to devise an indicator of ease of access to credit. The paper proposes an instrumental...

This paper explores how the interaction between firm heterogeneity, urban costs and transport costs determines spatial configuration across regions within a simple general-equilibrium model. We spot light on how firm heterogeneity affects the centrifugal and centripetal forces and reshapes the...

We estimate the effects of industrial localization on the spatial persistence of employment in the software industry. Locations with an initial concentration of software employment retain an excess number of employees, beyond that expected from job turnover and job persistence at the...
