Appendix 1: Input – oriented measures
Farrell illustrates his idea of technical efficiency using a simple example of firms using two inputs (x 1 and x 2 ) to produce one output (y) under constant returns to scale. Firms lying on the perfectly efficient isoquant, depicted by the curve SS' in the graph, allow for a measure of technical efficiency.
Technical efficiency by input approach

O
If firms use the inputs at point P to produce an output, then the firm's technical inefficiency is defined by the gap QP. This is the amount by which all inputs can be reduced without reducing output. This level of inefficiency is usually expressed as a percentage and is expressed as the ratio QP/OP. The firm's technical efficiency TE is measured by the ratio TE 1 = OQ/OP = 1 – QP/OP and ranges from 0 to 1. In this example, point Q is technically efficient because it lies on the efficiency isoquant.
This measure of efficiency assumes that the firm's production function is perfectly efficient, which is known. In practice, it is impossible to know the efficiency isoquant. Therefore, the efficiency isoquant must be estimated from sample data.
Farrell (1957) suggested using a non-parametric piecewise convex isoquant such that the observation points do not lie to the left or below it. And following this suggestion of Farrell, Charnes, Cooper and Rhodes (1978) developed the DEA model. The input minimizing DEA model is illustrated as follows:

O
Enterprises A, B and C are completely relatively efficient compared to other enterprises in the same research sample, so they are on the efficiency frontier. Enterprise P is not completely relatively efficient, so it is not on the efficiency frontier.
Appendix 2: Output – oriented measures
Output-oriented efficiency is the opposite of input-oriented efficiency. The difference between input-oriented and output-oriented efficiency is illustrated using a simple example of an output and an input as shown in Figures 1.3 and 1.4. According to Figure 1.3, under decreasing returns to scale, technical efficiency is represented by the function f(x) and the firm is inefficient at point P. Input-oriented technical efficiency is measured by the ratio AB/AP, while output-oriented technical efficiency is measured by the ratio CP/CD. The graph shows that these two ratios are different. According to Figure 3b, under constant returns to scale, input-oriented and output-oriented technical efficiency are equivalent.

Technical efficiency under conditions of variable output with scale Technical efficiency under conditions of constant output with scale
We can consider measuring technical efficiency in terms of the output bias for the two-output and one-input case. In the constant-return-to-scale case, technical efficiency can be calculated based on the unit production possibilities curve in two dimensions:
Technical efficiency based on production possibilities curve

Z'
The ZZ' curve is the unit production possibilities curve and point A is considered to be the inefficient point. The inefficient point A lies below the curve in this case because ZZ' represents the upper limit of the production possibilities frontier.
The output-oriented measure of efficiency can be defined as follows: The gap AB represents technical inefficiency. Therefore, it is the proportion of output that can be increased without requiring additional inputs. Then TE 0 = OA/OB. The output-maximizing DEA model is illustrated similarly to the input-minimizing DEA model.
DEA model maximizes output
