“…The dynamic of return on total assets at FB has been driven by return on sales, although the advantage in this margin was diluted during the previous decade to the point of disappearing in 2008, suggesting that their market power to translate differentiation into higher prices is low. This contradiction is not surprising considering the typical portrait of FB, revealing the persistence of important competitive disadvantages in key intangible assets for differentiation (Casillas, Moreno, & Barbero, 2011;Cooper, Upton, & Seaman, 2005;Kontinen & Ojala, 2010;Miller, McLeod, & Oh, 2001;Westhead, 1997), related to the lack of intellectual capital, knowledge (Block et al, 2011;Le Breton-Miller, Miller, & Lester, 2011) and innovation (Block, 2012;Chin, Chen, Kleinman, & Lee, 2009;Chrisman & Patel, 2012), and lower search breadth (Classen, Van Gils, Bammens, & Carree, 2012). As pointed out by Comi and Eppler (2014), family businesses lose their competitiveness as family managers are averse to taking entrepreneurial risks, over-exploiting existing competences and preventing the firm developing dynamic capabilities.…”
