Tariff-Based Product-Level Trade Elasticities

This repository contains all the SAS and STATA codes needed to replicate results in the manuscript "Tariff-Based Product-Level Trade Elasticities" by L. Fontagné, H. Guimbard and G. Orefice Abstract. Trade elasticity which varies widely across products is a crucial parameter in evaluating the welfare impacts of changes in trade frictions. We estimate trade elasticities at the product level by exploiting the variation in bilateral tariffs for each product category for the universe of country pairs over the 2001 to 2016 period. The predicted trade flows using the product-specific trade elasticities estimated here match the observed post-EPA import between the US and Chile, confirming the accuracy of our estimates.本仓库包含用于复现L. Fontagné、H. Guimbard与G. Orefice所撰写的论文《基于关税的产品层面贸易弹性》（Tariff-Based Product-Level Trade Elasticities）中所有研究结果所需的全部SAS与STATA代码。 摘要。 贸易弹性因产品而异且差异显著，是评估贸易摩擦变动所产生福利影响的关键参数。本文借助2001至2016年期间覆盖全球所有国家配对的各产品类别双边关税变动，估算了产品层面的贸易弹性。使用本文估算得到的产品特异性贸易弹性所预测的贸易流量，与美国和智利EPA生效后的进口观测值高度吻合，验证了本研究估算结果的准确性。
