International Transmission of Inequality through Trade
利用企业层面和加总数据，研究发现向更不平等国家出口会加剧国内不平等，并通过构建国际消费者细分模型解释了这一机制，模型校准表明国际不平等传导解释了观察到的基尼系数和顶层1%收入份额的约4.4%和4.8%。
I examine the international transmission of income inequality through trade. Using firm-level and aggregate data, I find that exporting to more unequal countries increases domestic inequality. I rationalize this finding by developing a model of international consumer targeting in which firms serve specific consumer segments in each market. Inequality in export markets shapes the distribution of firms’ profits and, therefore, the incomes of individuals linked to them, widening domestic inequality. The calibrated model suggests that international inequality transmission explains 4.4 percent and 4.8 percent of the observed levels of Gini coefficients and income shares of the top 1 percent, respectively.
