Abstract: The dynamic relationship between exchange rate movements (appreciation and depreciation) and macroeconomic fundamentals had preoccupied the minds of researchers across the globe. Consequently, extensive research works have been conducted to unravel the puzzle; however, the findings remain inconclusive. The inconclusiveness of these researches may not be unconnected with the choice of model, the omission of key variables and erroneous assumption of symmetric interrelationships of the variables. To mitigate such error and fill the observed research gaps, this study leveraged on the non-linear autoregressive distributed lag to trace the possible asymmetric pass-through of the exchange rate to output growth in Nigeria. The study made use of monthly time series for the period 2000M1–2018M12 for empirical estimations. The empirical findings reveal an asymmetric pass-through from exchange rate to productivity. Exchange rate depreciation led to output retardation in the short run, but neither appreciation nor depreciation of the exchange affected output in the long run. The findings highlight that exchange rate depreciation of the local currency does not improve the country’s productivity. This reveals a disconnection and misalignment between exchange and productivity in Nigeria. The findings call for proper alignment of the Naira exchange rate with the U.S. dollar for improved productivity in the economy.
