Additional Topics on Data Envelopment Analysis

This chapter continues the discussion of data envelopment analysis (DEA) which began in the previous chapter. In the previous chapter, we introduced the efficiency measurement concepts of Farrell (1957) and described how they could be implemented using the linear programming approach known as DEA. We discussed the basic constant returns to scale (CRS) and variable returns to scale (VRS) DEA models from both the input- and output-orientations.
