A Data Envelopment Analysis (Computer) Program This page describes the computer program DEAP Version 2.1 which was written by Tim Coelli. Spi serial flash programmer schematic drawings. 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 which contains all the necessary files. If you obtain a copy of the program you are advised to send some brief email to Tim Coelli at so that he can advise you of any bugs or new versions. If you have any technical questions regarding the use of this computer program you can contact Tim Coelli by email at. 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. FRONTIER is used to obtain maximum likelihood estimates of the parameters of a variety of stochastic production and cost frontiers, and estimates of mean and individual technical or cost efficiencies. The program can accommodate: • cross-sectional or panel data • half-normal or truncated normal distributions • any functional form which is linear in parameters • time-invariant or time-varying efficiencies • inefficiency effects can be explicitly influenced by a number of firm-specific factors. The program is compiled using a Lahey F77LEM/32 compiler for an IBM compatible PC. Persons who request a copy of the program receive the executable program file; the Fortran source code; some examples to practice with; and a 32 page user’s guide (in pdf format).

This is a Total factor Productivity Index Program which is used to calculate Tornqvist and Fisher TFP index numbers. The program can also calculate transitive versions of these index numbers using the EKS method. The program is compiled using a Lahey F77LEM/32 compiler for an IBM compatible PC. It is a DOS program.
