“…In this perspective, banks that hold a large amount of liquid assets are likely to perform less than banks investing in riskier assets (Goddard et al, 2013;Molyneux and Thornton, 1992). Apart from the impact of capital and of liquid assets holding on profitability, the literature focuses on other determinants of profitability such as market concentration (Bourke, 1989;Dietrich and Wanzenried, 2014;Molyneux and Thornton, 1992), cash and bank deposits (Bourke, 1989;Molyneux and Thornton, 1992), credit risks and loan loss provisions (Dietrich and Wanzenried, 2014;García-Herrero et al, 2009), tax variables (Albertazzi and Gambacorta, 2009;Chia and Whalley, 1999) and non-performing loans (García-Herrero et al, 2009). The impact of macroeconomic variables on profitability has also been assessed by many papers, for instance the impact of GDP growth rates (Bordeleau and Graham, 2010;Dietrich and Wanzenried, 2014), that of inflation (Bordeleau and Graham, 2010;Bourke, 1989;Dietrich and Wanzenried, 2014) and that of monetary policy (Borio et al, 2017).…”
