摘要：In "new economic geography" models, spatial concentration typically arises either because of worker mobility or because of vertical linkages among firms. We examine a setup that combines those two approaches in conjunction with local congestion costs. We find that, as trade costs are lowered, the spatial concentration of total activity ("agglomeration") follows an inverse u-shaped evolution, while the degree of specialization of locations increases. The evolution of spatial configurations accommodated by this model is consistent with changes in sectorial employment patterns within US metropolitan areas over the 1850-1990 period.
