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...

Two issues stand out in this conversation. The first concerns the unfinished business of the global fight against the scourge of poverty, which impacts one region more than most: Africa. At the same time, a key pre-requisite for economic performance - affordable and efficient public...
