From Santa Claus I wish the inclusion in Stata 10 - or, at least, on SSC for Stata 9 - of Data Envelopment Analysis (DEA) techniques including most recent advancements by:
JOHN SALERIAN & CHRIS CHAN; Restricting Multiple-Output Multiple-Input DEA
Models by Disaggregating the Output�Input Vector. Journal of Productivity Analysis, 24, 5�29, 2005
Leopold Simar & Paul W. Wilson; Estimation and inference in two-stage,
semi-parametric models of production processes. Journal of Econometrics 136 (2007) 31�64
I think they are not less important than stochastic frontier analysis, which are already included as built-in commands.
Merry Xmas,
Nicola
