Rentier state
In current political-science and international-relations theory, a rentier state ( RON-tee-ay or ) is a state which derives all or a substantial portion of its national revenues from the economic rent paid by foreign individuals, concerns or governments. The academic use of the term rentier states and rentier states theories (RST) became well known after the works of Hazem El Beblawi and Giacomo Luciani on the development of oil-rich countries, known as petrostates, in the Persian Gulf.
