Working Papers from New South Wales - School of Economics

Abstract: A firm may be an outlier either in terms of the mix of scale of its input-output vector. This paper develops separate mix and scale outlier measures. The mix measure is particularly relevant to Data Envelopment Analysis (DEA) since it will identify the firms thart exert influence on the resulting efficiency scores.
