On the long run effects of barriers to trade
(Escola de Pós-Graduação em Economia da FGV, 2001-10-17)
We study the macroeconomic effects of international trade policy by integrating a Hecksher-Ohlin trade model into an optimal-growth framework. The model predicts that a more open economy will have higher factor productivity. ...
