This work is based on the signalling theory that outlines the significance of organisations credibly conveying some relevant information about themselves to other parties – this is the signal (Spence 2001). Certo developed further the signalling theory to explain how information disseminated about the structure of the board of a firm “represents important nonfinancial information … when making investment decisions” (Certo 2003:432). Miller and del Carmen explore the signalling existing literature and they suggest that there is a link between board diversity and reputation.

Group decisions are more innovative as a consequence of abundant and varied information resulting from cognitive conflicts. Miller and del Carmen explore the behavioural theory and they point that there is a link between board diversity and innovation.
Based on the above mentioned theories a set of...
