While recent trade regime reforms and changes in transport and information technologies have greatly promoted international trade, a major remaining nontariff barrier derives from transport institutions inherited from the era of closed trade regimes.

Such progress in institutional reform is reviewed in the NAFTA, European Union and Mercosur trade regions.
