G7 ÜLKELERİNİN BANKALARININ SERMAYE YETERLİLİK RASYOLARI İLE KARLILIKLARI ARASINDAKİ İLİŞKİLER

Bu çalışmanın konusu G7 ülkelerinin bankalarının sermaye yeterlilik rasyolarının aktif getiri oranları arasındaki kısa ve uzun vadeli ilişki ile ilgilidir. Çalışmanın amacı panel veri analiz teknikleri ile G7 ülkelerinin bankalarının sermaye yeterlilik rasyolarının aktif getiri oranları ile arasındaki kısa vadeli ilişkiyi bulmak ve ARDL yöntemi ile uzun vadeli ilişkiyi bulmaktadır. Hausman testi kullanılarak modelde rassal etki olduğu tespit edilmiştir. Rassal etki modeli kullanıldığı için modele spesifik ülke etkisi ve spesifik zaman etkisi dahil edilmiştir. En düşük Akaike bilgi kriterine bakılarak en ideal ARDL modeli seçilmiştir. G7 ülkelerinin bankalarının panel veri setleri için analiz yapıldığında sermaye yeterlilik rasyosunun bankaların aktif getiri oranlarına 2000-2015 yılları arasında anlamlı ve negatif şekilde etki ettiği görülmüştür. Birleşik Krallığın ve 2004, 2005, 2006 yıllarının modelde önemli bir etkiye sahip olduğu bulunmuştur. Buna ek olarak, sermaye yeterlilik rasyosunun uzun vadede aktif getiri oranlarına anlamlı ve negatif şekilde etki ettiği gözlemlenmiştir.

THE RELATIONSHIPS BETWEEN G7 COUNTRIES BANKS CAPITAL ADEQUACY RATIOS AND PROFITABILITIES

Research topic is about the relationship between G7 countries’ banks capital adequacy ratios and return on asset ratios. By using panel data analysis techniques, the short-term relationship G7 countries’ banks capital adequacy ratios and return on asset ratios will be found. In addition, by using ARDL model, the long-term relationship between capital adequacy and return on asset ratios will be found. By using Hausman test, it has been found that there is random effect in the model. Since random effect model is used, specific country effect and specific time effect is included in the model. By looking at lowest AIC scores, optimum ARDL model was chosen. When analysis is done for G7 countries’ banks panel data, it was observed that capital adequacy ratio has significant negative impact on return on asset ratios for the period between 2000-2015. UK and years of 2004, 2005, 2006 has significant impact in the model. In addition to that, it was observed that capital adequacy ratios have significant and negative impact on return on asset ratios for the long term.
