Purpose This study aims to analyze the effects of natural resource rents on income inequality. Design/methodology/approach This study uses a panel quantile regression (QR) approach for 42 Sub-Saharan African (SSA) countries over the period 1998–2018. Findings The results show that natural resource rents have a negative and statistically significant effect on income inequality. Regarding the types of resources, the results show that coal rents increase inequality, while forestry and oil rents reduce income inequality. The results also show that the effects of mining and gas rents vary along the income inequality distribution. Finally, the results reveal a negative and significant effect of natural resource rents on income inequality in all sub-regions except Southern Africa. Practical implications The results suggest that the SSA Governments should intensify the implementation of income redistribution policies such as family allowances to poor families with multiple children and public sector job creation. SSA policymakers should also increase access to electricity, and internet, and allocate a portion of oil revenues to create an intergenerational sovereign wealth fund. Originality/value First, few studies have analyzed the effects of various types of natural resource rents on income inequality. To this end, this study used the QR method to examine the impact of natural resource rents on inequality, by laying emphasis on various types of natural resources. This study takes into account the likely heterogeneity across countries that may exist when considering a sample such as SSA countries, by examining the effects in the different sub-regions that make up this part of Africa (Central Africa, West Africa, Southern Africa and East Africa).

L’objectif de cet article est d’évaluer et d’analyser le potentiel commercial des pays de la CEMAC selon l’approche de l’intégration économique par le marché. Pour y parvenir, nous adoptons une démarche en plusieurs étapes. Après une analyse des faits stylisés, un modèle de gravité est appliqué et estimé selon plusieurs variantes pour évaluer les déterminants des échanges commerciaux. Les résultats obtenus sont ensuite utilisés pour le calcul du potentiel commercial communautaire. Nous parvenons aux principaux résultats suivants : (i) les faits stylisés montrent que les pays de la CEMAC sont faiblement intégrés commercialement, extravertis et hétérogènes; (ii) les coefficients des variables traditionnelles du modèle de gravité sont globalement de signes attendus; (iii) le faible niveau de revenu par habitant et surtout la faible diversification productive réduisent fortement le potentiel commercial dans la sous-région; (iv) des épisodes de création d’échanges, quoiqu’à un niveau faible, apparaissent, notamment dans les flux bilatéraux du Cameroun avec les autres États membres.This paper aims to evaluate and analyze trade potential of Monetary and Economic Community of Central Africa’s countries (MECCA) in the light of market integration theory. Gradually, we analyze stylized facts of member’s countries trade and estimate an augmented gravity model to evaluate the bilateral trade patterns in the subregion. The results obtained are used to compute the trade potential index in the community. The study found four major results: (i) the stylized facts show heterogeneity and a low level of integration in the subregion; (ii) the coefficients of the traditional variables of the gravity model globally keep their theoretical signs; (iii) the poor level of GDP per capita and the lack of diversification of productive structures are the main factors reducing trade potential in the sub-region; (iv) even though weak, there is some trade creation episodes, notably in the bilateral flows of Cameroon and others member’s countries
