Abstract: This research has focused on a number of important issues related to efficiency measurement. First, as was shown in this research, traditional measures may be a poor measure of performance in the presence of slack and the lack of value information. As a solution to this problem, value efficiency-the weighted global measure was introduced. One contribution of this research was to show that this measure may not perform better than traditional measures if inputs and outputs do not have equal factor weights in the production process. The major contribution was the development of an alternative model that both allows non-radial reduction in inputs and augmentation in outputs and incorporates unequal factor weights. In addition, this new measure of technical inefficiency combines production function estimation as part of a first stage and incorporates the resulting weights into a model. This measure is also useful for ranking efficient units, the units with undesirable inputs or outputs and the units without inputs or outputs.
