This paper examines whether the relatedness of populations across the world shapes international trade flows. Using data on common ancestry for 172 countries covering more than 99% of global trade, we document that country pairs with weaker ancestral relationships are less likely to trade with each other (extensive margin) and, if they do trade, they exchange fewer goods and smaller volumes (intensive margin). The effect of ancestry is robust to a vast array of micro-geographic control variables and mitigated, yet still sizable and significant, when controlling for other measures of cultural distance as well as for current migrant stocks.

血统与国际贸易

本文研究了世界各地人口的相关性是否影响了国际贸易流动。使用覆盖全球 99% 以上贸易的 172 个国家的共同祖先数据，我们记录了祖先关系较弱的国家对彼此进行贸易的可能性较小（边际较大），如果他们进行贸易，他们交换的商品和较小的交易量（密集保证金）。血统对大量微观地理控制变量的影响是稳健的，并且在控制其他文化距离度量以及当前的移民存量时，血统的影响仍然是可观的和显着的。
