Impact of Bankruptcy Risk and Competition on Profitability in the Iranian Banking System Using BOONE Indicator: Generalized Method of Moments
Abstract
The purpose of this study is to investigate the question that how is the impact of bankruptcy risk and improving competitive conditions on the profitability of commercial banks. We have studied the balance sheet information of 30 commercial banks, which include all Iranian banks, during the period 2006-2017. In this paper, the BOONE indicator is used to estimate competition, and to estimate profitability, two methods of rate of return on asset (ROTAB) and net interest margin (NIM) are used. The data analysis method in this study was based on the generalized least squares (GMM). The results showed that in the rate of return method, the impact of competition on the profitability of commercial banks, both in the deposit market and in the non-interest income market, was inverse and significant, and in the facility market, it has a positive and significant impact on the profitability of the banks.
