Abstract

The aim of this article is to highlight the impact of some characteristics of board of directors and CEO΄ duality on firms΄ innovation and performance. A series of hypotheses testing the links between the variables was formulated in the basis of a theoretical review. A quantitative research was performed via a questionnaire on a sample of 60 Tunisian listed companies. Moreover, we used a database published by the Stock Exchange of Tunisian Market and the Financial Market Council. Results of the empirical analysis show that innovation positively contributes to firms΄ financial performance. Findings reveal also that CEO΄ duality is negatively associated to innovation. This research may represent potential guide for the board of directors in order to improve firms΄ innovation and firms΄ financial performance.

Keywords: CEO-duality, innovation, financial performance, board size, independent directors, Tunisia.
