Analysis of the authors' rights collection frontier using PCA-MDEA: an application to the valencia region

Abstract

If we use the modification proposed by Anderson and Peterson (Modified Data Envelopment Analysis (MDEA), 1993), we will additonally be able to establish categories within the efficient units themselves, constituting a more precise collection frontier. p. 151 From a basic DEA model, Anderson and Petersen (1993) proposed a simple modification to the programme; the central idea of this MDEA (Modified DEA) is the exclusion of the evaluated unit of the reference group, so it allows the comparison of both inefficient and efficient units. p. 152 It may be pointed out, nevertheless, that in spite of Andersen and Petersen(1993) explaining that their method is applicable under variable returns to scale, Xue and Harker (1999) affirm that possible infeasibility problems may exist. p. 152 Formel auf Seite 152 fur maximierungsproblem outputorientierung
