We study the effects of a decrease in trade costs on the spatial distribution of industry in a multi-regional economy, when a rise in the regional population of workers generates higher urban costs. We show that high and low trade costs imply that all regions involve a positive share of the...

New economic geography models predict migration flows from peripheral regions toward central ones. Agglomeration occurs in these models because firms, which tend to locate in large demand regions, and workers, who look for high real wages, are driven by the same force defined by the market...
