摘要

隐性知识的传播涉及直接的人际互动。这意味着知识的国际传播应遵循国际移徙的模式。我们用导致新出口的跨国生产率溢出作为知识扩散的代理来检验这一观点。我们发现，特定产品出口国的移民增加10%，东道国在未来十年开始“从零开始”出口该产品的可能性就会增加2%。高技能移民的结果似乎更强，移民的质量相似，并且在重力框架中对移民进行了强有力的测量。

Migration, Knowledge Diffusion and the Comparative Advantage of Nations

The diffusion of tacit knowledge involves direct human interactions. This implies that the international diffusion of knowledge should follow the pattern of international migration. We test this idea using cross-country productivity spillovers leading to new exports as proxy for knowledge diffusion. We find that a 10% increase in immigration from exporters of a given product is associated with a 2% increase in the likelihood that the host country starts exporting that good ‘from scratch’ in the next decade. The results appear stronger for highly-skilled migrants, qualitatively similar for emigrants and robust to instrumenting for migration in a gravity framework.
