Article dans une revue: 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.
