Resumen:
This paper summarizes the macro and microeconomic determinants of tariff andantidumping (AD) barriers in Argentina, Brazil and Mexico using pre- and post-2008 Great Recession trade and protection data. As to tariff barriers, institutional agreements appear to have kept applied tariff in control after the crisis, while the positive impact of intra-industry trade reveals the governmental dependence on tariff revenue in both Sud-American countries. As to AD determinants, the evidence indicates that Argentina have further increased AD investigations after the crisis as a complement to tariff. Finally, the Great Recession has not reinforced the relationship between movements in the exchange rate and the start of an AD procedure.
