Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous - "trade-cost elasticity" plays a central role in computing general equilibrium trade-flow and...

We develop a novel two-stage methodology that allows us to study the empirical determinants of the ex post effects of past free trade agreements (FTAs) as well as obtain ex ante predictions for the effects of future FTAs. We first identify 908 unique estimates of the effects of FTAs on different...

We discuss recent regional trade and economic partnership agreements involving the large population rapidly growing economies (Brazil, Russia, China, India, South Africa, ASEAN, Mexico) who (with the exception of Mexico) are also outside of the OECD. Perhaps 50 out of 300 that exist worldwide...

We develop a new theoretical framework of trade agreement (TA) formation, called a "parallel contest", that emphasizes the political fight over TA ratification within countries. TA ratification is inherently uncertain in each country, where anti- and pro-trade interest groups contest each other...

Geo-political tensions and disruptions to global value chains have led policy makers to re-evaluate their approach to globalisation. Many countries are considering friend-shoring - trading primarily with countries sharing similar values - as a way of minimising exposure to weaponisation of trade...

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...

This paper analyses the effect of international borders and of trade agreements at international borders on subnational (i.e. regional) growth. We construct an extensive panel dataset covering 1,350 regions in 86 countries worldwide between 1950 and 2017. Our results show that international...
