Bankacılık Sektöründe Rekabet ile Mali Sağlamlık Arasındaki İlişkinin İncelenmesi: Gelişmekte Olan Ülkeler için Panel ARDL Modeli

Rekabet, çoğu sektörde verimliliği arttırdığı ve yeniliği teşvik ettiği için genellikle itici bir güç olarak kabul edilmektedir. Finans sektöründe de ülkeler rekabeti arttırıcı reformlar gerçekleştirmektedir. Bu çalışmada, 1996-2015 dönemi için 16 gelişmekte olan ülke bankacılık sektöründe, Panel ARDL havuzlanmış ortalama grup (PMG) tahmincisi kullanılarak, rekabet ile mali sağlamlık arasındaki ilişkinin incelenmesi amaçlanmıştır. Sonuçlar, rekabetin ve mali sağlamlığın hem uzun dönemde hem de kısa dönemde birlikte hareket ettiğini ortaya koymuştur. Ayrıca rekabetin uzun ve kısa dönemde finansal sağlamlık üzerinde negatif bir etkisi olduğu tespit edilmiştir. Elde edilen bulgular gelişmekte olan ülke bankacılık sektörlerinde “rekabet-kırılganlık” görüşünü destekler niteliktedir.

Testing The Relationship between Competition and Soundness in Banking Sector: Panel ARDL Model in Emerging Countries

Competition is generally considered as a positive driving force in many sectors as it enhances efficiency and promotes innovation. In the financial sector, countries are implementing reforms that increase competition. This study aims to examine the relationship between competition and financial soundness employing Panel ARDL pooled mean group (PMG) estimations in 16 emerging countries’ banking sectors for 1996-2015 periods. Results show that competition and financial soundness are moving together in the short and long-run. Also, it is found that competition has a negative effect on financial soundness in the short and long-run. Findings tend to support “competition-fragility” approach in emerging country banking sectors.
