CIRJE-F-414. Tabuchi, Takatoshi and Jacques-Francois Thisse, "Self-organizing Urban Hierarchy", April 2006.

We have considered a general equilibrium model with monopolistically competitive markets, in which urban centers are service suppliers to all the agricultural regions as well as to the other urban centers. We have retained the forward and backward linkages of NEG to generate the agglomeration of firms and workers in cities. Our main result is that central places arise endogenously when transport costs take intermediate values.
