This paper explores the growth-enhancing role played by heterogeneity in human capital accumulation. It develops a growth model that takes into account more than one mechanism for accumulating human capital; in particular, schooling and on-the-job training are considered. The paper demonstrates...

We examine the impact of natural disasters on GDP per capita by applying the synthetic control approach. Our analysis encompasses two large-scale earthquakes that occurred in two different Italian regions in 1976 and 1980. We show that the short-term effects are negligible in both regions,...

Unit roots in output, an exponential 2 per cent rate of convergence and no change in the underlying dynamics of output seem to be three stylized facts that cannot go together. This paper extends the Solow-Swan growth model allowing for cross-sectional heterogeneity. In this framework, aggregate...

This paper presents an endogenous growth models with intertemporally dependent preferences and "Ak" technology. We derive sufficient conditions for a balanced growth path to be an equilibrium, provide a full characterization of the equilibrium dynamics of the economy, and explore the...

We empirically characterize the sectoral distribution of firm size for a set of European countries, finding substantial differences. We then study the relationship between productivity growth at the sectoral level and size structure. We find a positive and robust association between average firm...

We introduce a novel methodology to measure the relative TFP of the tradeable sector across countries, based on the relationship between trade and TFP in the model of Eaton and Kortum (2002). The logic of our approach is to measure TFP not from its "primitive" (the production function) but from...

We analyze the foundations of the relationship between trade and total factor productivity (TFP) in the Ricardian model. Under general assumptions about the autarky distributions of industry productivities, trade openness raises TFP. This is due to the selection effect of international...
