Bank characteristics effect on capital structure: Evidence from PMG and CS-ARDL

The main aim of this paper was to investigate the impact of bank characteristics on capital structure empirically. The study employed a panel data analysis, Pooled Mean Group (PMG) and Cross-Sectionally Augmented Autoregressive Distributed Lag (CS-ARDL) estimators were utilized, for the period spans between the years 2008 and 2018. Both the borrowing (leverage) ratio and equity ratio used in the analysis cover short-term deposits and long-term deposits as a fundamental determinant variable on the capital structure. The main findings confirm that the deposit ratio has a positive relationship with the size of the bank. In other words, big banks use more foreign sources than small banks to use the tax shield advantage. At the same time, a percentage increase in bank size and liquidity ratio enhance the bank deposit rate by 0.0068% and 0.479%, respectively, in the long-run, while a percentage change in interest income coverage will reduce the bank deposit rate by 0.004% in the long-run. Meanwhile, the significant causal relationship of growth rate with the bank deposit rate could not be established. In addition, the short-run coefficients of the variables reveal that size, interest coverage, and liquidity have a positive and significant causal relationship with bank deposit rate in the short-run. The findings of the study are in line with the results of capital structure theories, especially the hierarchy theory and balancing theory.
