“…However, the net benefit of depreciation can only be positive if the elasticities of export and import sum up to a value greater than unity, i.e. the Marshall-Lerner condition (see Bahmani-Oskooee Ratha, 2004 or most recently Bahmani-Oskooee and Saha, 2017; Bahmani-Oskooee et al , 2018 for interesting insights).
