This article scrutinizes the leader’s emotional intelligence effect on the enterprises’ performance (diversification is the main strategy). After the theoretical discussion which approaches our subject matter, we propose our research assumptions. Thus, this research attempts to answer our central question: How can emotional intelligence affect the performance of Tunisian enterprises (diversifiable companies)? Our methodology consists of two parts. The first is used to identify the data sample selection and the second is devoted to the results interpretation. The main contribution of this work is to explain how the behavioral finance (we speak about emotional intelligence) allows to present answers regarding performance of companies (which the strategy the adopted is the diversification). The results obtained from the linear regressions made on a sample of the show well the significant and positive CEO emotional intelligent on the financial, social and environmental performance.

This research examines the determinants of firms’ investment introducing a behavioral perspective that has received little attention in corporate finance literature. The following central hypothesis emerges from a set of recently developed theories: Investment decisions are influenced not only by their fundamentals but also depend on different factors. One factor is the biasness of any CEO to their investment, biasness depends on the cognition and emotions, because some leaders use them as heuristic for the investment decision instead of fundamentals. Keeping this in view, this paper shows how CEO emotional bias (optimism, loss aversion and overconfidence) effects the investment decisions. I will use Bayesian Network Method to examine this relation. Emotional bias has been measured by means of a questionnaire comprising several items. As for the selected sample, it has been composed of some100 Tunisian executives. Our results have revealed that the behavioral analysis of investment decision implies leader affected by behavioral biases (optimism, loss aversion, and overconfidence) adjusts its investment choices based on their ability to assess alternatives (optimism and overconfidence) and risk perception (loss aversion) to create of shareholder value and ensure its place at the head of the management team.

This paper deals with the relationship existing between the emotional aspect and decision-making. More specifically, it examines the links between managerial optimism, and effectiveness of the investment decision. We introduce an approach based Decision Tree analysis with a series of semi-directive interviews. CEO optimism level was measured using a questionnaire with several items. As for the selected sample was composed of 100 Tunisian managers. The originality of this research paper is guaranteed since it traits the behavioral corporate policy choice in emergent markets. In the best of our knowledge, this is the first study in the Tunisian context that explores such area of research. Our results show that Tunisian optimistic leader who seeks the pioneering advantage for him and his company is encouraged to adjust its specific investment decision (investment, overinvestment or under-investment in the short term or long term ...) to ensure that advantage pioneer.

The aim of this article is to show, theoretically and empirically, the importance of the social responsibility of national companies in the creation of wealth. The aim is to explain the indirect relationship between economic growth and social responsibility. This relationship shows the effect of socially responsible investment on creativity, job creation, the innovation effort of companies and, subsequently, on economic growth. Analysis of the data collected revealed the importance of corporate social responsibility in explaining the positive variation in sectoral GDP. Empirical analysis of the relationship between corporate social responsibility and economic growth shows the role of socially responsible investment in explaining the wealth of nations. The social performance of companies has a positive impact on their levels of competitiveness, profitability, job creation and innovation. But it is negatively associated with value added. The analysis of economic growth through the integration of social responsibility is consistent with that of endogenous growth theory, which shows the importance of organisational learning (Through practice) as a factor in economic growth. From this point of view, the contribution of this study is to encourage Tunisian companies to invest in socially responsible projects and actions that create wealth.
