How Well is US Intrafirm Trade Measured?
利用美国经济分析局和人口普查局的两套独立数据，比较了美国企业内部贸易的衡量结果，发现两者总体一致，但差异需研究机密微观数据。
Using two independent data sources—the intrafirm trade data from the US Bureau of Economic Analysis and the related party trade data from the US Census Bureau—I construct and compare measures of US intrafirm exports and imports. I find that, in general, the two datasets provide similar measures of US intrafirm trade, particularly for exports. Understanding the differences that do exist in measurement will likely require study of the confidential micro data at both the Bureau of Economic Analysis and the Census Bureau.
