TThis paper investigates the persistence of profit in Turkish banking system for the period of 2004:1 – 2009:4 by focusing net income after tax to total equity (ROE) as profit measures by utilizing panel unit root tests. We found that competition among surviving banks is high in the Turkish...

This aim of this paper is to use asymmetric causality tests to examine the coal consumption and Gross Domestic Product (GDP) relationship in Turkey based on data from 1980 to 2006. To investigate this relationship, a multivariate system is employed by including fixed capital formation and labor...

Purchasing Power Parity has most likely been one of the most investigated issues of the last decades within economic literature. The results from such studies are not consistent and not only important for policy makers and economists but also extremely important for policy implications in...

This paper examines the unit root properties of energy consumption per capita for 15 East Asia & Pacific countries employing the Lagrange Multiplier (LM) panel unit root test with one structural break for 1971-2007. When we apply the LM univariate test without break, we find a unit root in per...

This study examines the validity of the purchasing power parity (PPP) in Turkey for annual data from 1953 to 2009. While results from both the ADF unit root and the DF-GLS unit root test indicate mixed results, PPP holds for Turkey with the presence of structural breaks which are obtained by...
