İKİ SINIRLI MALMQUIST VERİMLİLİK ENDEKSİ YÖNTEMİYLE ISO500 FİRMALARINDA DİNAMİK VERİMLİLİK ÖLÇÜMÜ

Öz

In the literature, it is observed that most of the Malmquist Productivity Index (MPI) studies use classical DEA models with an optimistic point of view. Since traditional DEA models do not include a pessimistic perspective, decision makers are deprived of some important managerial information. In this study, productivity analysis is performed using double frontier DEA-based MPI model, which addresses optimistic and pessimistic perspectives together. In the application, the productivity changes between the years 2018-2019 of 9 electrical equipment manufacturing firms listed in ISO500 firms announced by Istanbul Chamber of Industry (ISO) is conducted. Thanks to the proposed model, decision makers are given the opportunity to make a more comprehensive assessment by taking into account two conflicting perspectives simultaneously.
