The effect of the Global Financial Crisis on the market structure: The case of the Turkish banking sector

In this study, the market structure and competition level of the Turkish banking sector are investigated by employing a dynamic panel data method and using the data of the 2003-2018 period. For this purpose, within the framework of the non-structural Panzar-Rosse model, H statistical values were calculated for the period 2003-2018 and sub-periods 2003-2009 and 2010-2018 to investigate the effects of the Global Financial Crisis. According to the findings, the Turkish banking sector has a monopolistic competitive structure in the period of 2003-2018, in accordance with the classification in the literature. However, considering the structure of the Turkish banking sector, it can be stated that the sector has an oligopolistic structure. H statistical values also calculated for the 2003-2009 and 2010-2018 sub-periods that the level of competition in the sector is notably low, although the oligopolistic structure is maintained. Also, it is observed that the competition level of the sector decreased after the Global Financial Crisis, when the H statistics calculated for the two sub-periods are compared.
