Summary
Data Envelopment Analysis, or DEA, is a method for measuring efficiency. Students learn how to use DEAP software to apply DEA to real-world data.
Introduction to DEA
DEA is a non-parametric method for measuring production efficiency. It does not require any specific functional form. It measures technical efficiency, cost efficiency and scale efficiency.
Using DEAP Software
DEAP software helps apply DEA to real data. Students learn how to set up data files and run the software. It includes five files: the program, a start-up file, a data file, an instruction file and an output file.
Example Case
The document gives an example of using DEA to analyse seafood processing companies. It shows how to measure technical efficiency, allocation efficiency, cost efficiency and scale efficiency.
Key terms
- Data Envelopment Analysis
- A method for measuring production efficiency without assuming a specific functional form.
- Technical efficiency
- The ratio of actual output to the maximum possible output given the inputs.
- Allocation efficiency
- The ratio of actual input prices to the minimum possible input prices given the output.
- Scale efficiency
- The ratio of technical efficiency under constant returns to scale to technical efficiency under variable returns to scale.
- DEAP software
- A program for applying Data Envelopment Analysis to real data.
- Constant returns to scale
- A situation where output changes in proportion to changes in inputs.
Questions this document helps with
- How can DEA measure production efficiency?
- What files does DEAP software use?
- How do you set up a data file for DEAP?
