In this research, the Hausman test will be used to make my choice is (FFM) Fixed Effect model or Random Effect model (REM) to analyze impact factors on the net interest margins (NIM). In addition, the data serving for research come from the World Bank (WB) Indicators database and Bankscope database. According to the expected results, there will be three main group impacts on bank margins: the bank specific characteristics, the macroeconomic conditions, the banking market characteristics.
