Bu çalışmanın amacı, banka kartelinin Türkiye kredi pazarındaki rekabete olan etkisini ölçmektir. Buna yönelik olarak, alternatif arz ilişkisi tanımlarını temel alarak Bresnahan-Lau modelini kullandık. Sonuçlar, Turkiye’de bankaların kartel içerisinde olmadıkları dönemlerde tam rekabet koşullarında faaliyetlerini sürdürdüklerini göstermektedir. Ancak, kartelin aktif olarak yürütüldüğü Eylül 2007 ve Eylül 2011 ayları arasındaki dönemde, kredi pazarındaki rekabet önemli seviyede zarar görmüştür. Tüm alternatif model tanımlamaları, banka kartelinin kredi pazarındaki rekabeti olumsuz yönde etkilediğine işaret etmektedir.

Anticompetitive Effects of the Banking Cartel in Turkish Loan Market

Öz

The aim of this paper is to measure the effect of the banking cartel on the competition in the Turkish loan market. In doing this, we use Bresnahan-Lau model with alternative supply relation definitions. Our results suggest that Turkish banks operate in the perfectly competitive conditions during the non-cartel period. However, with the enforcement of the cartel actively between September 2007 and September 2011, the competition intensity in the market was damaged significantly. All alternative models witness the robust conclusion that the banking cartel affected the competition in the loan market adversely.
