What impact do remittances have on stimulating overall economic growth? Remittances can be used for consumption and investment which further stimulates demand for goods and services, as well as contribute to financial development. On the other hand, they can create dependence in recipients and cause real exchange-rate appreciation which adversely affects domestic production.
The answer is an empirical one which we can answer using available data. Our findings echo recent economic research which shows that remittances, even when not invested directly, can have an important multiplier effect.
In our study, we focused only on the magnitude of the impact of remittances on aggregate demand in Bangladesh and calculated the traditional Keynesian multiplier effect, that is how much income is generated from every remittance dollar, following the approach adopted by Nicholas Glytsos by estimating a consumption function, an investment function, and an imports function. To estimate the parameters we used data from the Bangladesh Bureau of Statistics national accounts covering the period 1981-2010. We ran simple Ordinary Least Squares regressions to estimate the structural parameters. Here is a summary of our results:
