The literature on the macroeconomic effects of remittances is inconclusive. This study establishes a relationship between remittances and other important macroeconomic variables, such as consumption, investment and economic growth in Bangladesh, Egypt, Pakistan, and Syria over the period 1975-2006. Overall results suggest that remittances have a positive impact on economic growth in Pakistan and Syria but a negative impact in Bangladesh and Egypt. Negative remittance-growth coefficients in those two countries suggest a counter-cyclical relationship. A key objective of this paper is to identify how the remittance behavior of migrants varies across countries. Results from panel estimation procedure shows that a combination of self-interest and enlightened self-interest behavior of migrants is responsible for the growth impact in Bangladesh. The enlightened self-interest motivation is also the most likely cause of the growth impact in Egypt. Finally, the self-interest behavior explains the growth impacts in Pakistan and Syria. Results from this paper have policy implications for developing countries which face dilemmas and debates on the impact of remittances on economic growth.
