We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-differences within the structural gravity model. To test the ETWFE, we estimate the effects of regional trade agreements (RTAs). The results suggest that RTA estimates in the current gravity literature may be...

Preferential trade agreements (PTAs) are signed between two or more countries following the conclusion of the negotiation process. The duration of this process varies considerably across existing trade agreements and ranges between 316 and 5125 days. This paper presents the consequences of the...
