Effects of regional integration on FDI: An empirical approach

This study uses an augmented gravity model to capture the effect of regional economic integration on Foreign Direct Investment (FDI) flows in the cases of the EU, NAFTA, MERCOSUR, and ASEAN. Three important conclusions emerge: (i) regional integration has had a positive and significant effect on FDI, which is a combination of investment creation and diversion; (ii) investment diversion does occur in a significant number of cases, and hence it is a legitimate cause for concern, especially among developing countries that are not part of a regional grouping with at least one developed country; and (iii) FDI acts as a substitute for trade in a significant number of cases, although in some cases, it complements trade.
