      abstract = {A generalization of Shephard's distance functions is  proposed, extending the usefulness of distance functions in  economic analysis. Applications to efficiency measurements  and productivity analysis are presented. New indexes of  productivity, and technical, allocative and scale  efficiency are proposed and analyzed. Interpretation of  these indexes in terms of ray-average cost, ray-average  revenue, and cost-to-revenue ratio is discussed.},
