“…Nevertheless, conclusions are not consistent as the analyses arrived at different conclusions. On the one hand, a positive effect of firm size on profitability emanated from the explosion of economies of scale and of economies of scope, the lower cost to access capital than smaller firms, the generation of higher income, the better access to capital markets or the lower cost of borrowing (Titman and Wessels, 1988;Barbosa and Louri, 2005;Stierwald, 2009;Argyrou et al, 2016;Genovevo da Costa et al, 2017). On the other hand, studies have found a non-important (Ha-Brookshire, 2009) or a negative effect of firm size on profitability (Zhou and de Wit, 2009;Yasuda, 2005;Almus and Nerlinger, 2000;Bottazzi and Secchi, 2006;Calvo, 2006;Dunne and Hughes, 1994;Goddard et al, 2002), which is due to increased monitoring costs, bureaucratisation, policies based on non-pecuniary benefits, diseconomies of scale or diversified production structure (Glancey, 1998;Barbosa and Louri, 2005).…”
