Estimating the Trade Elasticity over Time

Abstract

Using quarterly data on the U.S. imports from its major trading partners and the corresponding trade costs, this paper estimates the trade elasticity by using a panel structural vector autoregressive model that can distinguish between short-run versus long-run elasticity measures in a continuous way and is robust to any endogeneity problem. The estimated trade elasticity measures are highly consistent with studies in alternative literatures, suggesting a short-run value of about 1 (after one quarter), a medium-run value of about 5 (after one year), and a long-run value of about 7 (after five years).
