“…In view of this, a closer look at the model and its components would be of great help to expand our knowledge on diversity not only in Top management teams (TMTs) but also in boards of directors (BODs) that can be viewed in the same context as TMT (Hofman, Lheureux and Lamond, 1997) and it should be noted that it is not organizational performance rather financial performance that is being investigated here and demographic diversity is represented by gender and ethnic diversity (Roberson and Park, 2007;Conyon and mallin, 1997;Daily et al, 1999;Zander, 1979;Costa and Kahn, 2003;Kang and Cnaan, 1995;Rutledge, 1994;Widmer, 1987;Martin and Midgley, 1999;Carson, Mosley and Boyar, 2004). Therefore, these arguments allow us to develop a set of directional hypotheses that explain the impact of the demographic diversity in TMTs and BODs on firm financial performance, thus the following hypotheses are proposed:…”
