a) Migrant workers send monies as gifts to their relatives in their home countries, they increase the purchasing power of their relatives. More money equals more purchasing power. This purchasing power is futher magnified by the (in many cases) huge difference in purchasing power between the currency in the migrants home country and the country of temporary residence.
b) migrant workers send remittances in order maximize the added purchasing power afforded by the huge variances in exchange rate. These monies sometimes are gifted to family members to help them or for some other project to be executed on behalf of the migrant.
