      abstract = {This paper was conceived as an extension of the  contribution by Kopp (1981) in developing an approach to  efficiency measure that synthesizes. Farrell efficiency  measure and the frontier production function. The extension  is in the aspect of providing a measure for comparing  productive efficiency differential between two groups of  firms existing in the same competitive industry. To test  the efficiency differential, we proposed the Mann-Whitney  Test Statistic. As an illustration of the proposed measure,  we used data from three Malaysian agricultural processing  industries, that is, rice milling, rubber remilling and  oilpalm processing. In the exercise, we estimated and test  the technical efficiency differential between private and  public firms in each industry and found that in rice  milling and rubber remilling, private firms are technically  more efficiency than their public counterpart. In oilpalm  processing, the two groups of firms are equally efficient  (or equally inefficient).},
