Abstract

Bu çalışmanın amacı finansal serbestleşmenin bankaların etkinliği üzerindeki etkisini analiz etmektir. Çalışmada finansal serbestleşme dışında yer alan ekonomik özgürlük göstergeleri ve yönetimsel ve kurumsal düzenlemelerin bankaların etkinliği üzerindeki etkisi de ortaya konulmaktadır. Analiz kısmı iki aşamadan oluşmaktadır. Birinci aşamada 2005 -2017 yılları arasında Türk bankacılık sektöründe faaliyet gösteren 26 mevduat bankasının etkinlik skorları veri zarflama analizi ile hesaplanmaktadır. İkinci aşamada yönetimsel göstergeler ve bankaya özgü kontrol değişkenleri veri iken, finansal serbestleşme endeksinin bankanın etkinlik skorları üzerindeki etkisi Simar ve Wilson’un (2007) dirençli bootstrap yöntemi ile tahmin edilmektedir. Ayrıca tahmin edilen katsayılar parçalı logit tahmincisi ile duyarlılık analizi çerçevesinde dirençlilik analizine tabi tutulmaktadır. Elde edilen sonuçlar, ekonomik özgürlük göstergelerinden finansal serbestleşme endeksi ile bankanın etkinlik skorları arasında pozitif bir ilişkinin olduğunu göstermektedir. Bu sonuca göre, finansal serbestleşmeye yönelik politikalar, bir yandan bankaların gelirlerini maksimize etmelerine imkân verirken; diğer yandan etkinlik kanalıyla finansal kaynakların optimal dağılımının yapılmasına katkı sağlayabilir. Ayrıca Türk Bankacılık sektöründe kurumsal düzenlemeler yoluyla etkinliğin artırılabileceği ve bu yolla maliyetlerin azaltılabileceği yönünde bir genel bulguya ulaşılmıştır.

The Impact of Financial Freedom on Bank Efficiency: Evidence from A TwoStage Double-Bootstrap Data Envelopment Analysis

Abstract

The objective of this study is to investigate the impact of financial liberalization on the efficiency of banks. In the study, the effects of administrative and institutional regulations on efficiency are also presented. The analysis consists of two stages. In the first stage, the efficiency scores of 26 deposit banks operating in the Turkish banking industry between 2005 and 2017 are estimated by Data Envelopment Analysis. In the second stage, the impact of the financial liberalization on a bank’s efficiency is estimated by the bootstrap method of Simar and Wilson (2007). In addition, the estimated coefficients are subjected to robustness analysis within the framework of the fractional logit estimator. The results confirm that there is a positive correlation between the financial liberalization index, which is one of the indicators of economic freedom, and the efficiency of the banks. Accordingly, financial liberalization policies can contribute to the optimal allocation of financial resources through efficiency channel, while making it possible for banks to maximize their profit. In addition, a general finding has been obtained that the efficiency in the Turkish Banking sector can be increased through institutional regulations and the associated costs could be reduced.
