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 …. Population growth exhibits a U-shaped relationship with initial population density, and only becomes uncorrelated with initial …

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 …

start with the relation between development and rural-urban migration. Moving beyond the coarse rural-urban distinction, we … with development. As we discuss, these spatial dynamics often mask important differences across sectors. We then turn our … development, we draw on empirical evidence from both the historical evolution of today's developed economies and comparisons …

We present a theory of spatial development. A continuum of locations in a geographic area choose each period how much … to innovate (if at all) in manufacturing and services. Locations can trade subject to transport costs and technology … diffuses spatially across locations. The result is an endogenous growth theory that can shed light on the link between the …

This regime leads to large development …Interactions between economic development and financial development are studied by looking at the roles of financial … institutions in selecting R&D projects (including both imitation and innovation).

This Paper studies the theoretical micro-foundations of urban agglomeration economies. We distinguish three types of … characterization of some of the main theoretical underpinnings of urban agglomeration economies, to discuss modeling issues that arise … when working with these tools, and to compare different sources of agglomeration economies in terms of the aggregate urban …
