Çalışmanın temel amacı, rekabet ve riskin önemli ölçüde farklılaştığı son yıllarda bankalarda rekabet ile risk alma davranışı arasındaki ilişkiyi sorgulamak ve yeni kanıtlar sunmaktır. Ayrıca, finansal gelişmişlik düzeyinin rekabet ve risk arasındaki ilişkiye etkisinin sorgulanması da amaçlanmaktadır. Bu bağlamda çalışma literatürde ilk olma özelliği taşımaktadır. OECD (Ekonomik İşbirliği ve Kalkınma Örgütü) üye ülkelerinde faaliyet gösteren 6,478 bankanın 2013-2021 dönemi verileri ile kapsamlı bir çalışma yürütülmüştür. Analiz sonuçlarına göre, rekabet ile risk alma davranışı arasında elde edilen bulgular, ‘Rekabet-istikrar’ görüşü ile tutarlıdır. Sonuçlar ayrıca ‘Doğrusal olmayan’ görüş ile de tutarlı olup, bankaların sektörün durumuna göre aldıkları pozisyona göre oluşan rekabet ile risk alma davranışı arasında doğrusal olmayan bir ilişki olduğunu ortaya koymaktadır.

Does Banking Competition Enhance or Mitigate Risk? New Evidence from OECD Countries

Öz

The primary aim of the study is to question the relationship between competition and risk-taking behavior in banks in recent years, when competition and risks have significantly differentiated, and to provide new evidence. In addition, it is also aimed to question the impact of the level of financial development on the relationship between competition and risk. In this context, the study is the first of its kind in the literature. A comprehensive study was conducted with the data of 6,478 banks operating in OECD (Organization for Economic Co-operation and Development) member countries for the period 2013-2021. Panel data analysis results obtained from the nexus between competition and risk-taking behavior are found to be consistent with the ‘Competition-stability’ view. The results are also consistent with the ‘Non-linear’ view, revealing a non-linear relationship between competition and risk-taking behavior, which is formed according to banks' actions by the position they have taken according to the situation of the sector.
