Resource Curse Analysis

Resource dependence — the share of resources in exports or GDP — is partly a symptom of underdevelopment: a country with no other industries mechanically has a high resource share, so dependence can be high precisely because the rest of the economy is weak. Resource abundance — the physical endowment or reserves per capita — is closer to an exogenous geological fact. Studies using dependence measures tend to find a curse, while several using abundance measures find resources are neutral or beneficial. The distinction is central to the debate because it bears directly on whether resources cause poor outcomes or merely correlate with them.

The modern consensus is that it is conditional. Mehlum, Moene, and Torvik showed that resource wealth tends to retard growth in countries with weak ('grabber-friendly') institutions but can promote it where institutions are strong ('producer-friendly'), implying the curse coefficient depends on institutional quality. This is why credible analyses include an interaction between resource dependence and institutional measures: the same resource windfall is a blessing in Norway and a curse in a kleptocracy, and a single unconditional coefficient masks that contingency.

Several strategies are used. One is instrumental variables, using exogenous geological endowment or proven reserves to instrument for observed dependence. Another is panel data with country fixed effects, which absorb stable national characteristics and exploit within-country changes in resource income, often driven by world price shocks interacted with endowment. Controlling for pre-existing institutions before the resource boom also helps separate the effect of resources from the institutions that may have predated them. Haber and Menaldo's panel approach, finding little within-country curse, illustrates how addressing endogeneity can temper the cross-sectional results.
