In political science, the term “rentier state” refers to a state that derives the majority of government revenues from the sale of domestic resources to external clients. Today, the term almost exclusively applies to the world’s major oil-producing states, particularly in the Middle East, Africa and Latin America, which boast massive state-controlled oil and gas reserves and firms to utilize them. Academics hypothesize on the effects of rentier economics on democratic, institutional, economic and human development, the general consensus being that the practice is rarely a good thing – the debate over the “oil curse” is a common one.
