Türk bankacılık sektöründe karlılığın kalıcılığının incelenmesi

Artan rekabetin işletmeleri birçok şekilde etkilemesi beklenir. Yoğun rekabet altında özellikle işletmelerin normalüstü karlarının erimesi söz konusudur. Bu noktadan hareketle rekabetçi işletmelerde karlar kalıcılık gösteremeyerek uzun dönemde düşecektir. Çok sayıda ampirik çalışmada rekabet şartları altında normal üstü karların düşeceği hipotezi test edilmiştir. Bu çalışmada Türkiye’de bankacılık sisteminde Karlılığın Kalıcılığı (KK), aktif karlılığı verisi kullanılarak 1998 - 2009 dönemi için devamlılık gösteren 25 bankanın oluşturduğu panel veri seti ile SUR (Seeemingly Unrelated Regression) ve MADF (Multivariate Augmented Dickey Fuller) testleri kullanılarak incelenmiştir. Çalışmadan elde edilen sonuçlar, Türk bankalarında rekabet ortamının karlılığı etkilediğini ve karlılığın kalıcı olmadığını ortaya koymaktadır.

The research of profitability persistence in Turkish banking sector

It’s expected that the increasing competition will influence the firms on many ways. Under the competitive environment, firm’s abnormal profits will erode. On this context, profitability of competing firms will not be persistent in the long run and therefore decrease. The hypothesis which proposes that, under competition conditions the profits over the norms will decrease has been tested on many empirical studies. In this study Persistence of Profitability (PP) is researched by Return on Assets (ROA) data on a panel model for 25 surviving Turkish banks for the period 1998 – 2009, by Seemingly Unrelated Regression (SUR) and MADF (Multivariate Augmented Dickey Fuller) tests. The results indicate that the competition affects the profitability and profitability is not persistent in Turkish banks.
