Abstract: We propose a novel approach to estimate the trade elasticity at various horizons. When coun-tries change Most Favored Nation (MFN) tariffs, partners that trade on MFN terms experienceplausibly exogenous tariff changes. The differential effects on imports from these countries rela-tive to a control group – countries not subject to the MFN tariff scheme – can be used to identifythe trade elasticity. We build a panel dataset combining information on product-level tariffs andtrade flows covering 1995-2018, and estimate the trade elasticity at short and long horizons usinglocal projections (Jordà,2005). Our main findings are that the elasticity of tariff-exclusive tradeflows in the year following the exogenous tariff change is about−0.76, and the long-run elasticityranges from−1.75 to−2.25. Our long-run estimates are smaller than typical in the literature,and it takes 7-10 years to converge to the long run, implying that (i) the welfare gains from tradeare high and (ii) there are substantial convexities in the costs of adjusting export participation.
