Remittances and financial development: substitutes or complements in economic growth?

Recent studies indicate that the effect of migrants’ remittances on the economic growth of receiving countries depends negatively on the level of development of the domestic financial sector. In this paper, we introduce a new indicator of financial development to measure the efficiency of the domestic banking system, and find the existence of complementarity between remittances and bank efficiency in economic growth, such that remittances promote growth only in countries whose banks function well. This result is robust to controls for other traditional measures of financial depth and institutional quality indicators.
