A Data Envelopment
Analysis (Computer) Program
This page describes
the computer program DEAP Version
2.1 which was written by Tim Coelli.
This program is used to construct
DEA frontiers for the calculation
of technical and cost efficiencies
and also for the calculation of Malmquist
TFP Indices.
The program has three
principle DEA options:
- • Standard CRS and VRS DEA models
that involve the calculation of
technical and scale efficiencies
(where applicable).
- • The extension of the above models
to account for cost and allocative
efficiencies.
- • The application of Malmquist DEA
methods to panel data to calculate
indices of total factor productivity
(TFP) change; technological change;
technical efficiency change and
scale efficiency change.
All methods are available
in either an input or an output orientation
(with the exception of the cost efficiencies
option). The output from the program
includes, where applicable, technical,
scale, allocative and cost efficiency
estimates; slacks; peers; and TFP
indices.
The program is compiled
using a Lahey F77LEM/32 compiler for
an IBM compatible PC. The program
package includes the executable program;
data files for four simple examples;
and a 47 page user’s guide (in
pdf format).
If you wish to obtain
a copy of the program you can download
the zip file **DEAP-xp1.zip**
which contains all the necessary files.
If you obtain a copy
of the program you are advised to
send some brief email to me at t.coelli@economics.uq.edu.au
so that I am able to advise you of
any bugs or new versions.
For a description
of DEA methods and the presentation
of some worked examples using this
software please refer to our recently
released second edition of the book: An
Introduction to Efficiency and Productivity
Analysis.
If you have any technical
questions regarding the use of this
computer program you can contact me
by email at t.coelli@economics.uq.edu.au.
Brief questions (involving less than
10 minutes of time) will be answered
as quickly as is possible. A consultancy
service is available for those who
have more lengthy enquiries. Consultancy
fees will be provided on request. |
