| Research Abstract |
This study explores the method which allows the presence of environmental load factors in measuring the total factor productivity. For this end, treating environmental load factors as undesirable outputs, we model the technological relationship between producible desirable outputs and controllable undesirable outputs given inputs. This model is then utilized to measure the Hicks-Moorsteen-Bjurek productivity index extended by environmental load factors. The proposed procedure is applied to analyzing real data on the Japanese electric utility firms and the total factor productivity with environmental load factors and the shadow values of SO_2 and CO_2 are measured. This procedure is also applicable to testing scale and scope economies when environmental load factors exist.
