Devaluation on the trade balance in recent times emerged as a vital policy issue in Nigeria due to the recent economic crisis. This paper examines the nexus between devaluation and Nigeria’s trade balance by empirically investigating the Marshall-Lerner condition using annual data covering the period of 1986-2015. It also examines the dynamics of the relation between Nigeria’s trade balance and the real exchange rate. The Engel-Granger OLS-based Cointegration technique and the Error Correction Mechanism (ECM) modelling technique were employed to conduct these analyses. Findings suggest that the Marshall-Lerner condition is not satisfied in Nigeria and that real exchange rate has no significant effect on the trade balance both in the long-run and short-run. Also, findings revealed that income effects dominate price effects on trade in Nigeria.
