“…Recent studies that have incorporated asymmetry into exchange rate have focused mainly on export (Adaramola, 2016;Oyovwi, 2012;Rahman & Serletis, 2009;Verheyen, 2013), pass through (Bussiere, 2013), trade balance (Arize et al, 2017;Mohsen Bahmani-Oskooee et al, 2018;Buba, Garba, & Guza, 2018;Jibrilla Aliyu & Mohammed Tijjani, 2015;Kyophilavong, Shahbaz, Rehman, Souksavath, & Chanthasene, 2018;Nathaniel, 2020), reserve (Adler & Mora, 2011;Chen & Lin, 2019;Pontines & Rajan, 2011), inflation (Wimanda, 2014), etc. with little or no known study on the asymmetric effect of exchange rate on output especially in Africa which is one of the developing region and worst hit by factors that could make exchange rate respond asymmetrically.…”
