See More + Like many other developing countries, South Asian nations have been experiencing increased foreign direct investment inflows over the past decade as developing countries get a larger share of cross-border investments that were once sent to developed countries. Nonetheless, South Asia's inflows of foreign direct investment remain the lowest relative to gross domestic product among developing country regions. Why are South Asia's foreign direct investment inflows so low and what lessons can be drawn for developing countries as a whole? The analysis in this paper uses a novel empirical model that accounts for possible trends in convergence in the ratio of foreign direct investment to gross domestic product between countries and cross-sectional data for 78 countries from 2000 to 2011. The sample contains 52 developing countries. The analysis finds that two key factors are at work -- high overall regulatory restrictions on foreign direct investment and specific restrictions placed on doing business with other countries.
