Abstract
In this paper, we offer a non-parametric method of decomposing the Fis her Ideal index of productivity into individual factors measuring: (i) technical efficiency change, (ii) allocative efficiency change, (iii) shift in the cost function, (iv) scale economies due to output change , and (v) an adjustment factor reflecting change in the output attribu tes. Cross section data from the US airline industry for the years 198 3 and 1984 are utilised in an empirical application illustrating this method.
