On ratio-based RTS determination: An extension
We consider identifying the RTS status of DMUs in Weight-Restricted DEA models. We extend some of the results from our EJOR 2011 paper. Under suitable circumstances Constant Returns to Scale prevail. We also present partial results for another previously unresolved case. Our techniques are based on simple ratio calculations, and not on LP.
