Aim: Strategic alliance is defined as the act of two or more companies producing product or service together, acting in the direction of common interests for the sale of manufactured products or services. Today, especially those companies operating in the aviation industry seem to have established such strategic partnerships in order to adapt more rapidly to changing global conditions. In this study, it was aimed to perform a comparative efficiency analysis for the strategic alliances which established in the aviation industry Method: Additionally to basic Data Envelopment Analysis (DEA), Assurance Region approach was also applied to the 59 airline company and the interpretations of the findings were made with a different point of view in the light of this approach. Findings: In comparison with basic DEA, it was found quite different results under Assurance Region Method which consider weights of each input and output variables. Results: While mean efficiency score was found as %62 under basic DEA, however, it was found as %44 under DEA/AR approach. Theseresults show that efficiency score was decreased about %30 under DEA/AR approach. 11 airline company were found as efficient under basic DEA, only 3 of them were found as efficient under DEA/AR approach. And also, we can say that DEA/AR approach is more sensitive technique than basic DEA.

“…Consequently, some studies use only earning assets as outputs, a selection that is in line with an asset-wise approach, while others consider deposits as an extra output, a choice that is linked to a value-added approach. We find many applications in bank efficiency where the monetary value of deposits is part of the inputs (Tsionas et al , 2001; Drake and Hall, 2003; Pasiouras 2008) and a considerable number of studies where deposits are part of the output collection (Subramanyam and Reddy, 2008; Ulas and Keskin, 2015). Some studies, instead of using the net value of deposits, use interest expenses as an input (Athanassopoulos, 1997; Avkiran and Goto, 2011; Avkiran, 2015).…”

“…For instance, the traditional inputs, along with deposits, are fixed assets, personnel or expenses (Avkiran, 2011; Zao and Kang, 2015). In some papers, we find the use of branches (Kaur and Gupta, 2015; Ulas and Keskin, 2015), loan loss provisions (Drake and Hall, 2003; Tsonas et al , 2015) and equity (Kuosmanen and Post, 2001; Luo, 2003) as supplementary or alternate inputs. Another popular input is operating expenses (Yu et al , 2014, Tsolas and Charles, 2015).…”

Purpose The purpose of this paper is to examine the efficiency of the four largest Greek banking organizations for the period 2004–2014, including both a period of strong economic growth and a period of economic crisis and recession, which is still plaguing the Greek economy and more specifically the Greek banking sector. Design/methodology/approach The study incorporates the application of financial ratio analysis and the data envelopment analysis (DEA) in order to calculate the technical efficiency of Greek financial institutions. More specifically, a two-stage output-oriented DEA model is developed in order to estimate the global efficiency of banks. The banking function is considered as consisting of two stages in series, a service/operational efficiency and a profitability efficiency. In both output-oriented models, methods of constant returns to scale and variable returns to scale were applied. Findings The results show that in terms of operational efficiency, banks started from a low rate of return in 2004, which improved until 2008, which marked the peak of operational efficiency. By 2010, the operating efficiency varied with downward trend until 2012–2013. In terms of profitability efficiency, the image is clearer, since the impact the financial crisis had on bank’s profit efficiency led, by 2012, to a plunge in the average efficiency by 30–40 percent. Originality/value A multi-stage DEA process, input oriented, was used in order to estimate changes in the performance and efficiency of banking system. The period 2004–2014 has not been examined until recently and all previous studies used the output-oriented DEA model.

Data envelopment analysis is one of the tools that has been used frequently on evaluating the performance of the firms. Particularly in today's competitive conditions, since the firms have been facing many external and/or internal factors closely, data envelopment anaysis (DEA) method is used for measuring inputs and outputs on the relative efficiency of operational processes. When the banking sector is analysed in Republic of Turkey, the degree of competition among the banks has shown that it is necessary for them to use their resources more efficiently. Hence, in terms of financial performance of banks, defining the efficiency limitations would be easier and more efficient with some statistical tools. The purpose of this study is to analyze the performance of all deposit banks in Turkey by using data envelopment anaysis with entropic weights. Keywords:Data Envelopment Analysis, Banking Sector, Banking Performance, Entropic Weights TÜRK BANKACILIK SEKTÖRÜNÜN PERFORMANS DEĞERLENDİRMESİNDE ENTROPİK AĞIRLIKLARLA VERİ ZARFLAMA ANALİZİ ÖZVeri zarflama analizi firmaların performansını değerlendirmede sıklıkla kullanılan araçlardan birisidir. Özellikle günümüz rekabet şartlarında işletmelerin gerek dış gerekse iç faktörlere yakından maruz kalması ve bunun sonucunda girdi ve çıktıların operasyonel süreçlere göreli etkinliklerinin ölçülmesi için kullanılan bir yöntemdir. Türkiye'de bankacılık sektörü incelendiğinde bankalar arasındaki rekabetin düzeyi bankaların kaynak kullanımını en etkin şekilde kullanması gerektiğini göstermiştir. Bu yüzden bankaların finansal performansları açısından takip etmesi gereken etkinlik sınırlamalarının belirlenmesi bazı istatistiksel araçlarla daha kolay ve etkin olmaktadır. Bu çalışmanın amacı, entropik ağırlıkları içeren veri zarflama analizi ile Türkiye'de faaliyet gösteren tüm mevduat bankalarının performanslarının incelenmesidir.
