Competition and Stability: An Analysis of the Turkish Banking System

Tomak, Serpil

This paper examines the relationship between competition and stability in the Turkish banking sector using quarterly bank level data of 15 private commercial banks (domestic and foreigned-owned) between 2002-2012. There have been many theories stand out on the relationship between competition and stability of the banking sector so far. But theories of the competition-fragility view and competition-stability view are widely accepted theories in the literature. Dynamic panel data approach is employed to test the related tehories. However our findings indicate that the relationship between concentration and competition is not clear enough to emphasize a strict inference.

The Impact of Overconfidence on Capital Structure in Turkey

The aim of this study is to investigate the relationship between the overconfidence and capital structure in Turkish manufacturing firms. In addition to management confidence, the impact of the fundamental factors on the market leverage is analyzed. The annual data of 115 manufacturing firms on the Istanbul Stock Exchange (ISE) for the period between 2002 and 2011 is used for the analysis by means of the ordinary least squares regression model. The results show that the relationship between confidence and leverage is ambiguous. There isn’t enough evidence for the idea of overconfident managers tends to use more debt level. However, this study provides some evidence for firm specific factors like size and profitability effects on leverage.
