“…Besides economic activities, researchers explored other macro indicators as potential influencers of remittance outflows, which significantly improved the understanding of the sources of remittances volatility. Among these indicators is the interest rate and return on investment (or, in some studies, the interest rate differential between the host and home countries), which capture the investment motive and thus play a role in migrants' decisions to invest in the host or home country (El-Sakka and McNabb 1999;Aydas, Neyapti, and Metin-Ozcan 2005;Alleyne, Kirton, and McLeod 2008). Moreover, other studies have investigated the role of the exchange rate and (most of them) found that a depreciation in the home country's exchange rate has a positive impact on remittance outflows, as more funds can be transferred at low exchange rates (Higgins, Hysenbegasi, and Pozo 2004).…”
