Y’a-t-il vraiment un besoin pour changer de referentiel comptable au Maroc? la prétendue value relevance des normes comptables IFRS[Is there really a need to change accounting references in Morocco? the alleged value of IFRS accounting standards]

The adoption of IFRS aims to improve the quality of accounting, thus increasing its value to stakeholders. But often the adoption of these standards did not originate from an internal need of the emergent’s countries but are usually offered by international financial institutions that require "IFRS label" to align with the best practices of developed countries. The question that arises in this research is to know, beyond the motivations African companies to adopt IFRS; Ahsina (2012) and Sy and Tinker (2013), is that IFRS are of top quality local standards? A review of abundant literature was conducted in developed countries, but did not decide categorically on the superiority of IFRS by local standards. By cons, There are few studies on emerging markets as the Moroccan financial market, hence the usefulness of this work. This article is based on a model of price and yields developed by Amir et al (1993), Barth and Clinch (1996) and Harris and Muller (1999). This is to achieve association studies between market values and financial information from the national database by incorporating the differential amount resulting from the application of IFRS. The findings emerged from the study suggest that the informational relevance of IFRS is low for both models; the R2 is less than 30% for the first model and 10% for the second model. Thus, the obligation to adopt IFRS standards imposed by the AMF and the central bank of Morocco on the recommendations by international financial institutions, is not timely, since it did not leads to the production of more relevant financial information and of good quality.
