Disentangling the Impact of International Migration on Food and Nutrition Security of Left‑Behind Households: Evidence from Bangladesh

This paper explores the linkages between international migration and household food and nutrition security (FNS). First, building on existing literature, we discuss the main microeconomic channels through which international migration may affect household FNS. Second, taking Bangladesh as a case study, we estimate the overall impact of international migration on the FNS of left-behind households. Third, by disentangling the overall effect, we assess the importance of the various microeconomic channels that link international migration to household FNS. The empirical results suggest that international migration has a positive impact on the quantity, quality and variety of food consumed by left-behind households. Our findings also suggest that international migration might be considered among the possible drivers of the so-called Bangladesh paradox, i.e. the exceptional progress in health and nutrition achieved by the country during a period of relatively poor economic performance.
