"This paper investigates why Third World cities have been growing in the last several decades much more quickly than cities in industrialized countries. For this purpose, we develop a Krugman-type model of economic geography with two continents, North and South, each of which consisting of two regions, East and West. We study the impact different levels of transport costs and tariffs exert on the distribution of economic activities among the regions. We find that lower costs for transport between the regions in the South, for instance, induced by an improved infrastructure, as well as lower tariffs on intercontinental trade tend to lead to less concentrated economies."

本文探讨了为何在过去几十年里，第三世界城市的发展速度比工业化国家的城市快得多。为此，我们构建了一个克鲁格曼式的经济地理模型，该模型包含两大洲，即北方和南方，每个洲又由东部和西部两个地区组成。我们研究了不同水平的运输成本和关税对各地区经济活动分布的影响。我们发现，例如，南方地区内部各区域间运输成本的降低（如基础设施改善所致）以及洲际贸易关税的降低，往往会导致经济集聚程度降低。 （德语和法语摘要）
