The trade liberalization associated with NAFTA has affected the pattern of state exports by altering the origin as well as the destination of merchandise exports. We find that NAFTA has increased US merchandise exports to Mexico and Canada by just over 15 percent, and has increased total US merchandise exports by nearly 8 percent. We also find that although many states have seen large increases in exports to both Mexico and Canada, others have seen large decreases. NAFTA has also affected states. exports to non-NAFTA regions of the world, tending to decrease exports to Europe and Latin America and increase exports to Asia. States in the northeast regions of the United States have seen the smallest increases in exports in the wake of NAFTA.
