There is an extensive literature demonstrating a positive link between export diversification and economic growth. In parallel, the resource curse thesis posits export concentration as an important mechanism curtailing growth in mineral-rich countries. Our analysis contributes to this literature by empirically investigating the interaction between oil dependence captured by the share of oil rents in GDP and export diversification and economic growth for Sudan. We do this with the help of a VAR model using annual data between 1960 and 2018. In comparison to earlier studies, our dataset covers also Sudan’s post-oil boom period, which coincided with a substantial drop in oil dependence after the 2011 secession of South Sudan. We find that oil rents appear to have a statistically significant and negative effect on export diversification, although contemporaneously rather than in the long-term. However, we find no evidence of a statistically significant impact of either oil dependence or export diversification on economic growth, as suggested by the resource curse hypothesis.
