Using robust FDH estimates, we show how to decompose the overall inefficiency of a unit (a pupil) into a unit specific and a higher level (a school) component. By a sample of entry and exit attainments of 3017 girls in British ordinary single sex schools, we test the robustness of the non-parametric and parametric estimates. Finally, the paper uses the traditional MLM model in a best practice framework so that pupil and school efficiencies can be computed.

Mean and bold? On separating merger economies from structural efficiency gains in the drinking water sector / K. De Witte in Journal of the operational research society (JORS), Vol. 61 N° 2 (Fevrier 2010)  

Public ISBD [article]  inJournal of the operational research society (JORS) > Vol. 61 N° 2 (Fevrier 2010) . - pp. 222–234 Titre : Mean and bold? On separating merger economies from structural efficiency gains in the drinking water sector Type de document : texte imprimé Auteurs : K. De Witte, Auteur ; E. Dijkgraaf, Auteur Année de publication : 2011 Article en page(s) : pp. 222–234 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Mergers and acquisitions Efficiency Scale economies Water sector Nonparametric parametric estimation Index. décimale : 001.424 Résumé : The Dutch drinking water sector experienced two drastic changes over the last 10 years. Firstly, the sector association started a voluntary benchmarking aimed to increase the efficiency and effectiveness of the sector. Secondly, merger activity arose. This paper develops a nonparametric model to dissect and distinguish the effects on efficiency of these evolutions. Parametric corrected ordinarily least squares (Fourier) tests show the robustness of the model with respect to the specification and its variables. Although detecting an efficiency enhancing effect of benchmarking, we find insignificant merger economies due to the absence of scale economies and the absence of increased incentives to fight inefficiencies.
