Efficiency and cross efficiency measures: a validation using OECD data

This paper makes use of cross efficiency measures, a means of validating Data Envelopment Analysis (DEA) scores using different weighting schemes. It is demonstrated using data from 30 OECD countries. We recommend this as a means of bringing non stochastic DEA and stochastic modelling closer together, especially useful in modelling of health (and health care) production functions, given their multiple output nature.
