Abstract: | In this note we show how alternative measures of technical inefficiency at the industry level, evaluated along different direction vectors, are related to one another. Based on the homogeneity property of the directional technology distance function with respect to the direction vector, we verify that aggregate efficiency evaluated relative to the industry aggregate input-output vector is equal to the average of individual efficiency scores evaluated relative to the average input-output vector. |
