The asymmetric J-curve implies that there could be an asymmetric relationship between the exchange rate changes and trade balance. The asymmetric effects of real exchange rate on trade balance were initially reported by the American economist Mohsen Bahmani-Oskooee from the University of Wisconsin–Milwaukee. However, the term asymmetric J-curve was coined by the British economists Muhammad Ali Nasir and Mary Leung. They employed cumulative dynamic multiplier analysis and reported empirical evidence of an asymmetric J-curve in an article on US trade deficit.
