The banking
sector serves like a backbone for other sectors and the economy as a whole to
operate effectively. Therefore, market structure of the banking sector should
be followed closely and regulated. In this context, in the study the market
structure of the deposit sub-sector of Turkish banking sector is determined
through the estimation of market power. For the estimation, Bresnahan-Lau Model
is utilised and a non-linear system of equations comprising of two equations is
developed. The system is estimated simultaneously with the 2-SLS method and
with quarterly data for the period 2000-2013. According to the estimation results
the market power and the market structure of Turkish banking sector is
determined as 0.11 and monopolistic competition, respectively.

TÜRKİYE BANKACILIK SEKTÖRÜNDE PAZAR GÜCÜNÜN ÖLÇÜLMESİ

Öz

Bankacılık sektörü diğer sektörlerin ve bir bütün
olarak ekonominin etkin biçimde işlemesi için bel kemiği niteliğindedir.
Dolayısıyla bankacılık sektörü piyasa yapısının, yakından takip edilmesi ve
düzenlenmesi gerekir. Bu bağlamda çalışmada Türkiye bankacılık sektöründe
mevduat alt sektörünün piyasa yapısı, pazar gücünün ölçümü ile tespit
edilmiştir. Pazar gücünün ölçümü için Bresnahan-Lau Modeli kullanılmış ve
2000-2013 yıllarına ait çeyrek dönemlik veriler kullanılarak iki denklemli
doğrusal olmayan bir denklem sistemi geliştirilerek 2-SLS yöntemi kullanılarak
eş-anlı olarak tahmin edilmiştir. Tahmin sonuçlarına göre Türkiye bankacılık
sektörünün pazar gücü 0,11; piyasa yapısı ise tekelci rekabet olarak tespit
edilmiştir.
