Spatial development by Klaus Desment and Esteban Rossi - Hansberg December 2009

چکیده
We present a theory of spatial development. Manufacturing and services rms located in a continuous geographic area choose each period how much to innovate. Firms trade subject to transport costs and technology di¤uses spatially across locations. The result is a spatial endogenous growth theory that can shed light on the link between the evolution of economic activity over time and space. We apply the model to study the evolution of the U.S. economy in the last few decades and nd that the model can generate the reduction in the employment share in manufacturing, the increase in service productivity starting in the second part of the 1990s, the increase in the value and dispersion of land rents in the same period, as well as several other spatial and temporal patterns.

It has long been recognized that the forces that lead to the agglomeration of economic activity and to aggregate growth are similar. Unfortunately, few formal frameworks have been advanced to explore this link. We critically discuss the literature and present a simple framework that can circumvent some of the main obstacles we identify. We discuss the main characteristics of an equilibrium allo...
