Efficiency measurement when producers control pollutants: a non-parametric approach

Rødseth, Kenneth - In: Journal of Productivity Analysis 42 (2014) 2, pp. 211-223

This paper treats efficiency measurement when some outputs are undesirable and producers control pollutants by end-of-pipe or change-in-process abatement. A data envelopment analysis framework that compares producers with similar pollution control efforts is proposed. First, my approach avoids...

Cost, revenue and profit efficiency measurement in DEA: A directional distance function approach

Sahoo, Biresh K.; Mehdiloozad, Mahmood; Tone, Kaoru - In: European Journal of Operational Research 237 (2014) 3, pp. 921-931

Estimation of efficiency of firms in a non-competitive market characterized by heterogeneous inputs and outputs along with their varying prices is questionable when factor-based technology sets are used in data envelopment analysis (DEA). In this scenario, a value-based technology becomes an...
