Does trade openness cause higher GDP per capita? Since the seminal instrumental variables (IV) estimates of Frankel and Romer [F&R](1999) important doubts have surfaced.

We quantify the partial and general equilibrium effects of GATT/WTO membership on trade and welfare. Using an extensive database covering manufacturing trade for 186 countries over the period 1980-2016, we find that the average impact of GATT/WTO membership on trade among member countries is...

We build on the latest developments in the structural gravity literature to quantify the partial and general equilibrium effects of GATT/WTO membership on trade and welfare. Using an extensive database covering manufacturing trade for 186 countries over the period 1980-2016, we find that the...
