Quasi-fixed inputs are present in virtually all sectors of the economy and cannot be adjusted to their optimal value even in the long-run. This constraint must be incorporated in models to correctly measure efficiency and technological change. Assuming that all inputs can be freely and instantly set to their optimal level overestimates firms/sectors/countries' capacity to adjust, biases results, and weakens DEA method as a working tools for managers. We propose a modified DEA approach introducing quasi-fixed inputs and apply the method to hospital emergency services in Montreal to show that such limitations can be lifted. (C) 2002 Elsevier B.V.
