Trade–Exchange Rate Nexus in Sub-Saharan African Countries: Evidence from Panel Cointegration Analysis

This study explores international trade–exchange rate interaction in sub-Saharan African (SSA) countries. Based on partial equilibrium analysis, we develop two equations for export and import in which exchange rate, real gross domestic product (GDP), stock of capital and technology are the independent variables. The results from empirical analyses show that export and import are inelastic to changes in exchange rate. It follows that depreciation of currencies in the region may not have the expected results in view of the structure of the economies and export compositions. In the same vein, depreciation would not depress imports but only aggravate balance of payments. Thus, in the light of the findings, a policy of exchange rate stability that hinges on long-run considerations, capital accumulation and technological capacity as well as the maintenance of comprehensive coherent macroeconomic packages remains a critical factor in ensuring that exchange rate policy performs its central role as a trade facilitation tool
