Individuals consume differentiated goods (or services) and firms purchase differentiated inputs (or services) in product (or service) markets where forms compete under monopolistic competition. Workers rent their residential lots in an urban land market and contribute to the production of differentiated goods and inputs. We show that firms and workers co-agglomerate and endogenously form a city. We characterize and discuss the spatial distribution of firms and consumers in such cities on one- and twodimensional spaces (linear city and planar city). We show that final demand and vertical linkages raise the urban density and reduce the city spread. We finally show that a city is too much dispersed compared to the social optimum.
