【摘要】This paper introduces scale economies in transportation in a trade and geography modelwith heterogeneous firms. This relatively small change to the standard model produces a new patternof spatial sorting among firms. In contrast to the existing literature, our model produces the result thatfirms of intermediate productivity relocate to the large core region, whereas high- and low-productivityfirms remain in the periphery. Trade liberalization leads to a gradual relocation to the core with themost productive firms remaining in the periphery.
