Efficiency and Productivity [chapter]

Harold O. Fried, C. A. Knox Lovell, S. Schmidt Shelton
2008 The Measurement of Productive Efficiency and Productivity Change  
They constructed a "free disposal hull" (FDH) of the data that relaxes convexity while maintaining strong disposability and allowing for variable returns to scale.  ...  It truly does envelop a data set; it makes no accommodation for noise, and so does not "nearly" envelop a data set the way the deterministic kernel of a stochastic frontier does.  ...  oc (x t ,y t ,x t+1 ,µy t ) ≠ µ, µ>0 M oc (x t ,y t ,λx t ,y t+1 ) ≠ λ -1 , λ>0 M oc (x t ,y t ,λx t ,µy t ) = µ/λ, µ,λ>0 M4: Identity M oc (x,y,x,y) = 1 M5: Commensurability (independence of units of measurement  ...

Stochastic FDH/DEA estimators for frontier analysis

Léopold Simar, Valentin Zelenyuk
2010 Journal of Productivity Analysis

(1984) when only free disposabilty of inputs and outputs are assumed and Data Envelopment Analysis (DEA) estimator  ...
