These techniques allow us to develop a theory-consistent approach to the estimation of cross-sectional gravity equations that can accommodate the endogeneity of policy variables. We apply this approach to a data set in which the policy decision of interest is the engagement in a free trade agreement. We explore ways to exploit the transitivity observed in the formation of trade agreements to construct instrumental variables with considerable predictive ability. Within a bilateral model, the use of these instruments has strong theoretical foundations. We obtain point estimates of the partial effect of a preferential-trade agreement on trade volume that range between 20% and 30% and find no statistical evidence of endogeneity. publisher: TSE Working Paper date: 2021-11-19 type: Monograph type: NonPeerReviewed format: text language: en identifier: https://publications.ut-capitole.fr/id/eprint/44014/1/wp_tse-1271.pdf identifier: Jochmans, Koen and Verardi, Vincenzo (2021) Instrumental-Variable Estimation Of Exponential Regression Models With Two-Way Fixed Effects With An Application To Gravity Equations.
