Impact of COVID19 on the Islamic cryptocurrencies

Cryptocurrency is a new form of digital asset based on a network distributed across a large number of computers. The main objective of this work is to investigate the impact of COVID-19 on the Islamic cryptocurrency markets returns. In this methodology, we identify a group of Islamic cryptocurrencies consisting of the X8X, Hellogold and OneGram. This paper uses the Newey-West standard errors regression to estimate the effect of the COVID-19 pandemic on the Islamic cryptocurrencies returns. The empirical results show that COVID-19 total deaths have a negative effect on respectively the X8X cryptocurrency, HelloGold, and OneGram cryptocurrencies. In the same way, the COVID-19 total confirmed cases growth has a negative effect on respectively the X8X cryptocurrency, and OneGram cryptocurrencies. This study contributes to the literature by identifying the impact of COVID-19 on the Islamic cryptocurrency markets

A COGNITIVE APPROACH TO CORPORATE GOVERNANCE: A VISUALIZATION TEST OF MENTAL MODELS WITH THE COGNITIVE MAPPING TECHNIQUE

The idea of this paper is to determine the mental models of actors in the fi rm with respect to the cognitive approach of corporate governance. The paper takes a corporate governance perspective, discusses mental models and uses the cognitive map to view the diagrams showing the ways of thinking and the conceptualization of the cognitive approach. In addition, it employs a cognitive mapping technique. Returning to the systematic exploration of grids for each actor, it concludes that there is a balance of concepts expressing their cognitive orientation

Islamic view towards Bitcoin

This paper proposes to analyze the agent behavior by means of big data extracted from the search engine « Google trends » and Twitter API to visualize the emotions and the manner of thinking about « Bitcoin » in the Islamic context. Two kinds of sentiment measures are constructed. The first is based on the search query of the word « Bitcoin » with religious connotation all over the world from 14/04/2017 to 14/04/2018 in weekly frequency. The second is built on twitter data from 03/04/2018 to 13/04/2018, by using a Bayesian machine learning device exploiting deep natural language processing modules to assign emotions and sentiment orientations. In the next step, the Granger causality analysis is used to investigate the hypothesis that this sentiment causes the volatility and the returns of « Bitcoin ». The results show that, at a first-level that twitter users of the word « Islamic Bitcoin » improve positive sentiment. Secondly, the Twitter sentiment measure has a significant effect on lagged Bitcoin returns and volatility. Furthermore, this sentimental variable Granger causes Bitcoin returns and volatility.  This study contributes to the literature by studying the influence of the doctrinal view towards Bitcoin on his prices dynamics. Knowing that Bitcoin is a new financial asset and there is a large debate on his compliance with sharia

Influence des actionnaires institutionnels et dominants sur le comportement des dirigeants en matière de choix d'investissement : Une étude dans le contexte français de 1994 à 1998

Cet article examine l'hypothèse selon laquelle la présence d'actionnaires dominants ou d'investisseurs institutionnels dans le capital ou le conseil d'administration influence le comportement des dirigeants en matière d'horizon temporel et de risque des investissements (DRHTI) Les indicateurs retenus pour le DRHTI sont la volatilité de la rentabilité, le , le ratio R&D/Actif et le ratio Placement LT/CT. L'étude empirique se base sur des données françaises dans la période 1994-1998. Les résultats de l'étude empirique sont plutôt ambigus mais confirmeraient la thèse de la myopie des institutionnels et le rôle des actionnaires dominants dans l'orientation en long terme des choix des dirigeants. Ces résultats sont beaucoup plus nets lorsque l'échantillon est segmenté en fonction du caractère technologique de l'activité de la firme. Dans l'ensemble, les résultats obtenus vont dans le même sens que les travaux anglo-saxons sur ce même thème.Gouvernement de l'entreprise; actionnaires institutionnels; administrateurs institutionnels; actionnaires dominants; risque des investissements; horizon temporel des investissements

Normal, Abnormal Book-Tax Differences And Accounting Conservatism

The present paper investigates the effect of book-tax differences on the accounting conservatism (as a proxy for financial reporting quality). The major objective of this study was to examine the extent to which regulatory and opportunistic information in book- tax differences influence accounting conservatism. We also aim to examine if book-tax differences are a signal of “bad news” for investors. Using publicly available financial statements from 2005 to 2012 for 28 Tunisian listed firms on the Tunis Stock Exchange and operating in the industrial and commercial sectors, we use a current measure for accounting conservatism and documents that observation with large book-tax differences are associated with low levels of accounting conservatism. Also, we find that firms with abnormal book-tax differences and normal book-tax differences exhibit less accounting conservatism. Overall, the results suggest that the total and differing components of book- tax differences have differential implications on accounting conservatism. Our research is valuable for researchers, shareholders as well as regulators. For researchers, it appears to an innovative area for future research. For shareholders, it shows the role of the information transmitted by book-tax differences into the analysis of earnings quality published by firms. This study also helps regulators to improve accounting rules and tax rule

Environmental Audit and Environmental Disclosure Quality

In this study we explore the association between environmental audit and the quality of environmental disclosure as measured by voluntary and timely disclosure. Relying on a multiple theory framework and using a sample of 81 French non-financial companies listed on the SBF 120 index covering the six-year period from 2012 to 2017, we found a positive and statistically significant relationship between the level of voluntary disclosure of environmental information and the environmental audit committee, the environmental auditor's BIG 4, debt levels, firm size, earnings management, and the industry. In addition, findings indicate that the environmental audit committee, CSR committee, the environmental auditor's BIG 4, earnings management, firm size, and the industry have an impact on the timely disclosure of environmental information. However, the regression of the results showed that there is no relationship between CSR committee and the level of the voluntary disclosure of environmental disclosure.JEL Codes - M4

The Impact of Audit Characteristics on Corporate Tax Avoidance: The Moderating Role of Gender Diversity

The purpose of this paper is to investigate the relation between audit characteristics and corporate tax avoidance and how board gender diversity (BGDs) moderates this relationship. Using a sample of 270 UK firms over the 2005-2017 period, we find that audit characteristics influence the corporate tax avoidance. Two of them (specialization and audit fees) had a negative effect; the other one (audit opinion, audit rotation) Have a positive effect on tax avoidance. We also find that BGDs moderates the effect of audit characteristics on corporate tax avoidance, except for audit opinion. The impact of the BGDs’ level increases as the presence of woman in the board escalated from 40 to 60 %, but then weakened at 10 % level. This study contributes to the existing literature and auditing practices by extending the auditing and tax literature on the examination of the moderating effect of board gender diversity on the relation between audit characteristics and corporate tax avoidance using the sensitivity analysis.JEL Codes - H26; M14; M
