NEGATIVE VALUES IN DEA: EXAMINATION OF THE RELATIONSHIP BETWEEN ECONOMIC GROWTH RATES AND AIRLINE PERFORMANCES

Abstract

The main goal of this study is to determine whether there is a relationship between the economic growth rates and the performances of airline companies. From this point of view, Data Envelopment Analysis DEA is applied to star alliance member airlines for a period of 2012-2014. Firstly, the technical, pure technical and scale efficiency scores were calculated. Then, airlines are divided into four regional groups as America, Europe, Asia and Africa in order to determine the most efficient region. Further, countries economic growth rates which the airline is located are analyzed to support DEA results. Finally, Asia group is found as the most efficient airline group

DEA’DA NEGATİF DEĞERLER: HAVAYOLU PERFORMANSLARI VE EKONOMİK BÜYÜME ORANLARI ARASINDAKİ İLİŞKİNİN İNCELENMESİ

Öz

Bu çalışmanın genel amacı, ülkelerin ekonomik büyüme oranları ile o ülkede yer alan havayolu şirketlerinin performansları arasında bir ilişki olup olmadığını belirlemektir. Buradan hareketle, Star Alliance üyesi havayolu şirketlerinin 2012-2014 yılları arasındaki verileri üzerinde bir Veri Zarflama Analizi gerçekleştirilmiştir. Öncelikle, her bir havayolu şirketinin teknik ve ölçek etkinlikleri hesaplanmıştır. Daha sonra, havayolu şirketlerinin yer aldığı ülkeler, en verimli bölgeyi belirlemek amacıyla Amerika, Avrupa, Asya ve Afrika olmak üzere dört grup altında toplanmıştır. Veri Zarflama Analizi sonuçlarını destekleyebilmek ve verimlilik ile büyüme oranları arasında bir ilişki bulabilmek adına her bir ülkenin ekonomik büyüme oranları hesaplanmış ve sonuç olarak en verimli ve en yüksek büyüme oranına sahip bölge Asya bölgesi olmuştur.
