The aim of this study is to examine the relationship between board structure of commercial banks and their profitability in Turkey. The study covers the time period of 2007-2013 and dynamic panel regression models (Pooled OLS, fixed effects and system GMM estimators) are used in the analysis process. The variables such as board size, the proportion of independent directors, the proportion of foreign directors and the dual position of the chairman of the board and the general manager of the bank are used for the board characteristics. According to the results obtained from the study, there is no statistically significant association between board size and profitability. In addition, both the proportion of independent directors and the proportion of foreign directors are found to be negatively related to bank profitability. It has also been observed that the influence of dual position of the chairman of the board and general manager of the bank on profitability is positive. As for the control variables, there is no statistically significant link between bank size and lending level variables and profitability. However, the effect of bank capital on profitability is positive and statistically significant.

YÖNETİM KURULU YAPISI VE BANKA KARLILIĞI ARASINDAKİ İLİŞKİ: DİNAMİK PANEL VERİ ANALİZİ

Öz

Bu çalışmanın amacı, Türkiye’de mevduat bankalarının yönetim kurulu yapısı ile banka karlılığı arasındaki ilişkiyi incelemektir. Çalışma 2007-2013 dönemini kapsamaktadır ve analizlerde dinamik panel regresyon modelleri (Havuzlanmış EKK, sabit etkiler ve sistem GMM tahmincileri) kullanılmıştır. Yönetim kurulu değişkeni olarak, yönetim kurulunun büyüklüğü, bağımsız yönetici oranı, yabancı yönetici oranı ve liderlik yapısı değişkenleri kullanılmıştır. Çalışmadan elde edilen sonuçlara göre, yönetim kurulu büyüklüğü ile karlılık arasında istatistiksel olarak anlamlı bir ilişki bulunamamıştır. Hem yönetim kuruluna atanan bağımsız yönetici sayısı ile hem de yönetim kurulunda yer alan yabancı yönetici sayısı ile karlılık arasında negatif yönlü bir ilişki olduğu tespit edilmiştir. Genel müdürlük ve yönetim kurulu başkanlığı görevlerini aynı kişinin icra etmesi durumunun ise karlılığı artırdığı görülmüştür. Banka düzeyinde kullanılan kontrol değişkenlerinden banka büyüklüğü ve kredilendirme düzeyi değişkeni ile banka karlılığı arasında istatistiksel olarak anlamlı bir ilişki çıkmamıştır. Banka sermayesi değişkeni ile banka karlılığı arasında ise istatistiksel olarak anlamlı ve pozitif yönlü bir ilişki bulunmuştur.
