“…It was discovered that a percent change in interest rates will positively influence level of reserves. A nearest intention to the current study was indicated by Keskin (2021) which showed that social prosperity wasted by the OPEC members was about 40% while utilising about 60% for the development of their countries. This appeared to a general average as some would have gained more while other would have lot more.…”

“…In the proposed model, the inputs are considered crisp, and the outputs are considered fuzzy to solve the problem of vagueness and inaccuracy of the data. Keskin (2021) proposed a slacks-based network DEA model to assess the social prosperity efficiency levels of the OPEC member countries to consider whether these countries used their oil wealth effectively to increase the social prosperity in their countries.…”

“…In addition, the most of traditional DEA models are radial-based models, which assume the inputs and output change in the same proportion. It does not accommodate the slack inputs and outputs (slack means input excesses or output shortages), thus, these methods do not provide an accurate efficiency evaluation (Keskin, 2021).…”
