The type of exchange rate a country uses affects how much remittances (money sent by people working abroad) can boost its economy. A study looked at data from 135 developing countries from 1970 to 2007. It found that countries with flexible exchange rates see bigger economic growth from remittances. But even with a fixed exchange rate, remittances still help the economy grow. For every 1% increase in remittances, the economy grows by about 0.79% with a fixed exchange rate. And this growth can increase by 0.13% with more exchange rate flexibility. This effect is also positive in less financially developed countries, but the impact doesn't change much based on how flexible the exchange rate is.
