This paper develops new estimates of export quality, based on bilateral data, which are far more extensive than previous efforts. The data cover 166 countries and more than 800 products over the period 1962–2014. The analysis finds that, within any given product line, export quality on average converges rapidly across countries. However, there is also significant cross-country heterogeneity in the growth rate of quality. Institutional quality, liberal trade policies, foreign direct investment inflows, and human capital all promote quality upgrading, although their impacts vary across sectors.

发达和发展中经济体的出口质量：来自新数据集的证据

本文根据双边数据得出了出口质量的新估计值，其范围比以前的工作要广泛得多。数据覆盖1962-2014年间的166个国家和800多种产品。分析发现，在任何给定的产品系列中，平均而言，出口质量在各个国家之间迅速收敛。但是，跨国产品质量的增长率也存在明显的异质性。机构质量，自由贸易政策，外国直接投资流入和人力资本都促进质量升级，尽管它们的影响因行业而异。
