The current study analyses how CEO’s attributes could influence innovation. It is drawn on all listed firms on the SBF120 1 index between 2001 and 2013. Proxies for innovation effort are the ratio of R&D spending and the number of researchers/scientists per R&D team. First, we find that the CEO’s education background could influence innovation effort. Specifically, when CEOs have a science or an engineering degree, unlike business and management educated CEOs, they are more inclined to increase R&D spending. These effects are pronounced in innovative firms operating in sectors where innovation is not the heart core of their businesses. Also, we show that CEOs’ profile influence firms’ innovation investment only in non-technological industries. In high technological firms, attributes’ differences between CEOs are very small which may be due to high competition between firms listed on the SBF120 index. Finally, our results on the influence of gender diversity on boardrooms in Tech firms are consistent with the risk-avoidance hypothesis according to which women are risk averse agents.
The main objective of this article consists in determining the impact of the management power and the manager’s personal characteristics on the performance of the highly-rated enterprises. This paper examines two approaches. The first one specifies the leader’s power by referring to the management characteristics as a group of personal sociological and professional aspects. The second one is concerned with the effect of these characteristics on the companies’ performance. In order to test the validity of the theoretical hypotheses, the empirical study is based on a sample of 32 Tunisian highly-rated enterprises during the period 2000-2005. The results have shown that the leader’s power, made up of indicating variables, plays an important role on the stock exchange and accounting performance. This fact leads us to conclude that all management characteristics contribute to the reinforcement of this power and to its effects on the enterprises’ performance
