ISOLATION AND DEVELOPMENT
利用航海和航空技术出现前各国地理隔离程度的差异，研究其对全球经济发展进程的影响，发现史前地理隔离对发展有持续的正面作用，并解释了当今生活水平的跨国差异。
This paper exploits cross-country variation in the degree of geographical isolation, prior to the advent of seafaring and airborne transportation technologies, to examine its impact on the course of economic development across the globe. The empirical investigation establishes that prehistoric geographical isolation has generated a persistent beneficial effect on the process of development and contributed to the contemporary variation in the standard of living across countries.
