Abstract
The sheer size of remittances has fostered an interest in investigating the consequences of these flows, particularly in remittance-dependent economies. This study relies on monthly data from 1995M01 to 2021M05 and uses both frequency-domain and time-varying causality approaches to investigate the asymmetric causality relationships between real effective exchange rates and remittances in Mexico. Two key results are obtained. First, according to the frequency domain causality test results, positive shocks to remittances lead to appreciation in the Mexican peso in the medium- and long-run cycles, but negative shocks to remittances do not lead to depreciation in the Mexican peso, thus suggesting non-asymmetry. Second, the results of time-varying causality based on heterogeneous errors support asymmetric behavior between real effective exchange rates and remittances, underscoring the importance of allowing asymmetries when investigating the causal relationship.
