Although often seen as a path to prosperity, natural resources, especially oil, are associated with slow economic growth, authoritarianism, and civil war. Pathologies caused by natural resources are collectively referred to as the “resource curse,” and numerous scholarly works have been published on this subject over the past 20 years. This article reviews the political regime branch of the resource curse literature, classifying existing research into three categories. First, early studies found a negative relationship between oil and democracy. However, recent research casts serious doubt on this, arguing that there is no significant correlation between oil and political regimes or that the effects of oil are conditional on other factors, which respectively constitute the second and third categories of the resource curse literature. Notably, newer studies tend to qualify the original theory of the resource curse in some way, either spatially (i.e., arguing that the theory applies to only specific countries) or temporally (i.e., arguing it applies to only a specific time period). These spatial and temporal modifications might appear to be refinements of the theory, but this paper argues that they can also cause problems. Specifically, by focusing on particular countries in a particular time period, researchers can overlook the historical and international factors that led to the resource curse. Based on an extensive survey of the resource curse literature, this review article suggests that scholars can achieve a more comprehensive understanding of the causal relationship between natural resources and political regimes by taking the colonial period and the decolonization proctitess into account and considering the influence of international factors.
