Remittances are expected to exert a positive effect on economic growth. However, it seems difficult to provide strong and robust support for this idea. Indeed, empirical studies have typically showed contradictory results.
The effect of remittances on economic growth is sharply mixed. Sometimes, it appears positive, other times it seems negative, but mostly it is low and insignificant.
How can we explain this result? Is this due essentially to the quality of data? the different econometric methods used among studies? Or to the fact that the impact may be indirect via productivity, health, human capital, exchange rate (Dutch Disease), the volatility of economic growth and so on?
