The purpose of this study is to estimate an import demand and export supply function for Côte d'Ivoire. The econometric estimation was performed using the ARDL model on annual data from the World Bank database from 1985 to 2021. The results show that real income is a very important factor in the import demand and export supply of Côte d'Ivoire because in the short run, an increase in real income leads to a more than proportional increase in imports and exports from Côte d'Ivoire. In the long run, real income appears inelastic to import demand and export supply. Relative prices are inelastic to import demand and export supply in the short and long run. However, a rise in relative prices disadvantages imports and favors exports from Côte d'Ivoire. We recommend that Côte d'Ivoire's policymakers encourage and promote Ivorian exports and promote import demand for capital goods for the agribusiness industry.
