A simple derivation of scale elasticity in data envelopment analysis
No full textIn this paper, we Suggest a simple derivation of the formulae for the scale elasticity in the variable returns-to-scale technology as used in data envelopment analysis. Our development is consistent with the existing literature but the proof is much shorter and applies to the general case without any simplifying conditions. (C) 2008 Elsevier B.V. All rights reserved
