The aim of this paper is to investigate the relevance for stock market pricing of accounting earnings of voluntary disclosures in XBRL files considering the quality of corporate governance. Results are the following. It appears that XBRL extensions attract financial analysts. Good governance is positively associated with voluntary XBRL extensions. We observe that XBRL extensions enhance the positive relationship between accounting earnings and stock price. However, this positive association is reduced for firms with good governance, suggesting a substitution effect between XBRL extensions and corporate governance. Finally, it appears that XBRL extensions would strategically be related to earnings quality. This research highlights the importance to consider governance when assessing the value relevance of XBRL disclosures for stock market pricing.

International audienceThe purpose of this study is to prepare a diffusion model of the new international accounting standards known as the international financial reporting standards (IFRS). This model fits within the neo-institutional conceptual framework; more specifically, we used the DiMaggio/Powell analytical grid. Our desire to prepare this model was born from the observation that the analytical framework that is generally used to study the adoption of these new standards is the neo-institutional framework and that the principal methodologies implemented are qualitative. The question addressed in this study regards the forces leading an agent—in this case, an organisation providing standards for accounting—to adopt, at a given moment, these new standards. Existing studies, as interesting as they might be, are devoted to the question of adoption and leave aside the question of diffusion. In other words, the evolution of the system as a whole in time is ignored. Constructing a model appeared to us to be a way to move beyond these limitations. This model allows us to formalise the forces at work in the DiMaggio/Powell representation and to simulate the diffusion processes of the IFRS. To this end, we implement a multi-agent simulation. The various simulation scenarios are then compared to the observed diffusion of the IFRS

PurposeThis paper analyses the role of accounting information quality on leverage adjustments. More specifically, the authors investigate whether a better accounting information leads to a higher speed of adjustment to the target financial leverage.Design/methodology/approachThe authors use a two-step method. They first estimate the target financial structure and then the influence of accruals quality on the speed of adjustment to this target. The study sample consists of French listed companies in the CAC All-Tradable index. The sample contains 210 companies and 1,713 observations.FindingsAccounting literature showed the positive influence of accounting quality on financial management. The study findings are in line with these results. The authors give evidence of that a better quality of accruals is associated with a greater speed of adjustment.Research limitations/implicationsA common limitation in this field is the use of proxies. This makes results harder to generalize. For this reason, the authors implemented several models to improve the robustness of their results.Practical implicationsThe authors give evidence that firms have an incentive to disclose a good-quality accounting information. A weak accounting quality prevents firms from adjusting their leverage to their financial target and therefore reduce their value.Social implicationsThis work shows the need for accounting standardization bodies to strive to produce accounting standards allowing the production of high-quality accounting information. In a teaching dimension, these results highlight the importance in corporate finance of acquiring expertise in quality accounting information analysis.Originality/valueThis work is original because the authors study the influence of accounting quality on speed of adjustments of firms operating in the same legal environment and using the same accounting standards, when previous work compared different accounting frameworks. The French context is characterized by the weakness of market mechanisms and the important role of banks. These characteristics are known to reduce the role of accounting information in financing process. This result is interesting because the authors demonstrate that firms operating in this context still have an incentive in producing high accounting quality information.

Notre étude cherche à évaluer, dans un cadre théorique articulant le champ politique de la RSE et l’analyse institutionnelle comparée, la performance sociétale des entreprises dans différents modèles de capitalisme. Elle vise à interroger l’hypothèse très discutée de la convergence des différents modèles vers un type libéral anglo-saxon, dans un contexte de globalisation économique et financière. Nos résultats montrent que les modèles de capitalisme libéral, européen continental et social-démocrate demeurent soumis à des pressions institutionnelles qui impactent de manière différenciée la performance sociétale des entreprises nationales, remettant en cause l’hypothèse d’une convergence des pratiques sociétales entre économies de marché libéral et coordonnée.
