Ítem Solo Metadatos The specific factors of heterogeneity characterizing investors' beliefs(Universidad ESAN. ESAN Ediciones, 2024-03-30) Chenini, Hajer; Jarboui, AnisPurpose: A separate study of the different behavioral biases does not allow for a full understanding of the complexity and stability of the heterogeneity of beliefs. Therefore, through a more global view of these anomalies, the authors wish to show that they can converge on a single concept, which is the heterogeneity of beliefs. Design/methodology/approach: It is therefore essential to stress that the importance of this study is mainly reflected in the methodological approach used in the construction and analysis of the map and not only in the results achieved. This contribution states that structural analysis, as a means of building the cognitive map, can facilitate the task of investors and other decision-makers, in the identification and analysis of the heterogeneity of beliefs that can therefore guide investors' strategy in decision-making. Findings: The authors have studied the behavior of the investor and its way of interpreting the information and the authors have emphasized the value of studying the concept of heterogeneity of beliefs in its complexity. So that part of the work seems to be relevant and crucial to filling, if you will, that void. In this sense, the authors have shown that behavioral abnormalities are multidimensional concepts: “self-deception”, “cognitive bias”, “emotional bias” and “social bias”. Originality/value: In particular, this article will aim to achieve the objective of proposing a model for measuring the heterogeneity of beliefs. Thus, the authors want to show that the heterogeneity of beliefs can be measured directly through the different behavioral anomalies.Ítem Solo Metadatos The relationship between dividend policy and earnings management: a causality analysis(Universidad ESAN. ESAN Ediciones, 2024-03-30) Ben Salah, Olfa; Jarboui, AnisPurpose: The objective of this paper is to investigate the direction of the causal relationship between dividend policy (DP) and earnings management (EM). Design/methodology/approach: This research utilizes the panel data analysis to investigate the causal relationship between EM and DP. It provides empirical insights based on a sample of 280 French nonfinancial companies listed on the CAC All-Tradable index during the period of 2008–2015. The study initiates with a Granger causality examination on the unbalanced panel data and employs a dynamic panel approach with the generalized method of moments (GMM). It further estimates the empirical models simultaneously using the three-stage least squares (3SLS) method and the iterative triple least squares (iterative 3SLS) method. Findings: The estimation of our various empirical models confirms the presence of a bidirectional causal relationship between DP and EM. Practical implications: Our study highlights the prevalence of EM in the French context, particularly within DP. It underscores the need for regulatory bodies, the Ministry of Finance, external auditors and stock exchange organizers to prioritize governance mechanisms for improving the quality of financial information disclosed by companies. Originality/value: This research is, to the best of our knowledge, the first is to extensively investigate the reciprocal causal relationship between DP and EM in France. Previous studies have not placed a significant emphasis on exploring this bidirectional link between these two variables.Ítem Solo Metadatos Institutional investors, corporate governance, and earnings management around merger: Evidence from French absorbing firms(Universidad ESAN. ESAN Ediciones, 2013-12-30) Njah, Mouna; Jarboui, AnisThis paper examines the association between institutional ownership and the earnings management beha-vior of some French absorbing firms. Using a sample of 76 French mergers and absorptions concluded over the period ranging from 2000 to 2010, we undertake to present some empirical evidence highlighting that absorbing-firms manipulate earnings relevant to the year preceding the merger-offer in the presence of institutional cross-holding. However, the presence of active institutions turns out to limit the managerial accruals discretion. The monitoring role exerted by the active-institutional investors does restrict the oppor-tunities of earnings management around mergers and acquisitions. Further analyses suggest that the average value of discretionary accruals with regards to the absorbing firms proves to be influenced by the nature of merger deal (takeover vs. restructuring).Ítem Solo Metadatos External audit quality and ownership structure: interaction and impact on earnings management of industrial and commercial Tunisian sectors(Universidad ESAN. ESAN Ediciones, 2014-12-30) Kouaib, Amel; Jarboui, AnisThis article emphasizes the significance of researching the cross effect of using jointly external audit quality and ownership structure over managerial discretion in a largely unexplored non-Western and emerging context. The analysis is based on a sample of 61 Tunisian firms listed and unlisted on the Tunis Stock Exchange and operating in the industrial and commercial sectors during the period 2007-2011. To provide evidence on this topic we conduct an empirical examination. First we examine the effect of external audit quality and ownership structure on the discretionary accruals for the whole sample. We find that only auditor reputation has a negative and significant effect on earnings management. Second this article provides empirical evidence on the cross effect of external audit quality variables and capital concentration on earnings management. This test suggests that this combination has a negative and significant effect on earnings management in industrial firms but it has a positive and non significant effect in commercial firms. Finally the third empirical test concerns the combined effect of external audit quality and institutional property on earnings management.We find that the cross effect of this combined relation is negatively and significantly associated with earnings management of industrial firms but it has no significant effect on the earnings management of commercial firms. As for the cross effect of the auditor seniority and the institutional property it has a positive and a significant effect in the commercial sectors while it is positively and non-significantly associated with earnings management of industrial firms.Ítem Solo Metadatos Does innovation strategy affect financial, social and environmental performance?(Universidad ESAN. ESAN Ediciones, 2016-06-01) Ezzi, Ferdaws; Jarboui, AnisIn the very study the emphasis lays on the specific problem of analyzing the impact of the innovation strategy (in particular investment in research and development) on the financial social and environmental performance. After discussing this subject theoretically we propose our research hypotheses which in turn will be corroborated by an empirical study of 96 Tunisian companies. Indeed the results are noteworthy and important to the extent that one can say that the innovation strategy has a crucial impact on the performance of the companies.
