This Paper links the performance of new technology firms, measured in terms of growth, to geographic location. We introduce a model of firm growth that is specific to characteristics of the location as well as the firm and industry. The model is estimated using a new dataset identifying the...

This paper provides evidence that learning about demand is an important driver of firms' dynamics. We present a simple model with Bayesian learning in which firms are uncertain about their idiosyncratic demand parameter in each of the markets they serve, and update their beliefs as noisy...

This Paper studies the welfare implications of the location decisions of innovative newcomers that, though spinning off an industrial district, may choose whether to locate inside or outside its borders. Even if this choice has always been relevant, globalization has turned the issue, whether to...

Digital goods are bit strings, sequences of 0s and 1s, that have economic value. They are distinguished from other goods by five characteristics: digital goods are non-rival, infinitely expansible, discrete, aspatial, and recombinant. The New Economy is one where the economics of digital goods...

This paper constructs a model of endogenous growth and endogenous industry location where the two interact. We show that with global spillovers in R&D, a high growth rate and a high level of transaction costs are associated with relocation of the newly created firms to the South (the location...

We investigate the sources of productivity convergence using panel data for the Spanish regions. As a framwork, we develop a simple descriptive growth model which allows for factor accumulation, technological diffusion and rate effects from human capital and which includes fixed regional effects...

The literature on localised knowledge spillovers and growth focuses on the relative importance of intra vs. inter-industry externalities, but the nature and the characteristics of the dynamic linkages across manufacturing sectors are not investigated. In this Paper we perform a very...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

This paper explores the interactions between external trade and regional disparities in the Italian economy since unification. It argues that the advantage of the North was initially based on natural advantage (in particular the endowment of water, intensive in silk production). From 1880...

This paper presents new evidence on urbanization using sub-county data for the United States from 1880-2000 and municipality data for Brazil from 1970-2000. We show that the two central stylized features of population growth for cities - Gibrat's Law and a stable population distribution - are...
