This book aims to investigate the impact of financial liberalization on the performance of the Algerian public banks. In order to achieve this goal, a quantitative analysis has been conducted for a panel data sample covering five public banks over the period (1997-2012). The model used includes the determinants of performance. This later is estimated by using return on assets (ROA), return on equity (ROE), and net interest margin (NIM). Besides, the financial liberalization measures are: the size of intermediation which is measured by both the ratio of M2 to GDP and CP to GDP, Real interest rate, and bank concentration. The study showed evidence that the size of intermediation impacts positively the performance of public Algerian banks. It showed equally that bank concentration impacts positively the banks' performance. In contrast, it showed that real interest rates do not impact the performance of public Algerian banks. ukryj opis
