For this, we’ve employed a panel method for 30 Iranian provinces during time period 2003-2007. The estimation results suggest that the new economic geography provides a good description of the spatial structure of wages in the provinces of Iran. Our findings indicate that market size and distance-weighted will have positive relationship with wages. The overall result of this study corroborates the notion of centralization in the Iranian economy. The large wage variations explained by economic geography could cause significant internal migration. http://pubs.sciepub.com/ajmo/1/3/6/ajmo-1-3-6.pdf new economic geographyspatial structure of wagecentralizationsize of markettransport costs
