RT Generic T1 Spatial Development A1 Desmet, Klaus A1 Rossi-Hansberg, Esteban AB 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 diĀ¤uses spatially across locations. The result is an endogenous growth theory that can shed lighton 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 that the model can generate the reduction in the employment share in manufacturing, the increase in service productivity in the second part of the 1990s, the increase in land rents in the same period, as well as several other spatial and temporal patterns.
