DEA
DEA-NETWORK: Two-Stage Network DEA with Undesirable Outputs
Fukuyama, H., Weber, W. L. · 2010
Method assistant
Grounded explanations: it explains the method, it does not compute.
Assumptions to verify
- •Two-stage production structure is appropriate for the application
- •Intermediate products clearly defined and measurable
- •Bad outputs jointly produced with good outputs (not separable)
- •All data strictly positive
When not to use
- •Production structure has no intermediate products: use standard DEA
- •No undesirable outputs: use standard two-stage network without weak disposability
- •Small sample (J < 3*(N+Q+M+L))
