Economic Integration and Income Convergence: Not Such a Strong Link?
检验1870-1914年全球化与两次世界大战间经济解体对收入趋同的影响，发现两次大战间趋同更强，贸易保护对趋同影响不显著，质疑贸易驱动趋同的观点。
We would expect that the process of globalization between 1870 and 1914 and subsequent disintegration of the world economy during the interwar period would have led first to income convergence and then to income divergence between the participating countries. But in fact we find stronger evidence for income convergence during the interwar period than during the first globalization. Similarly, the average level of import protection in the world cannot be shown to have either helped or hampered convergence. The evidence for trade-induced convergence is therefore weak.
