DOES TECHNOLOGICAL PROGRESS MAGNIFY REGIONAL DISPARITIES?
研究了制造业技术进步与迁移成本如何相互作用，塑造空间经济格局，发现生产率提高促进集聚，而运输成本下降促进分散，最终结果取决于两者与迁移成本的互动。
Abstract We study how technological progress in manufacturing and migration costs interact to shape the space economy. Rising labor productivity in the manufacturing sector fosters the agglomeration of activities, whereas falling transport costs associated with technological and organizational innovations foster their dispersion. Since these two forces have been at work for a long time, the final outcome must depend on how drops in the costs of producing and trading goods interact with the various costs borne by migrants. Various extensions show the robustness of these conclusions.
