Abstract
|
|
|
|
|
We
derive a measure of scale efficiency change in the case
of a translog output-oriented, multi-input, multi-output
distance function without imposing restrictions in
previous analogous works by Ray (1998, 1999) and Balk
(2001). This may be particularly useful in productivity
analysis based on the Malmquist productivity index.
