An analysis of the effect of mandatory adoption of IAS/IFRS on earnings management

This paper examines whether mandatory adoption of international accounting standards, IAS/IFRS, by French companies is associated with lower earnings management. In addition, the impact of six factors that may be related to earnings management level are also considered: the independence and the efficiency of the board of directors, the separation of roles of CEO and Chairman of the board, the existence of an independent audit committee, the existence of block shareholders, the quality of the external audit and the listing on foreign financial markets.Based on a sample of 353 French listed groups relating to the period 2003–2006, our results show that the mandatory adoption of IAS/IFRS is associated with a reduction in the earnings management level. In addition, the independence and the efficiency of the board of directors, the existence of an independent audit committee, the existence of block shareholders, the quality of the external audit and the listing on foreign financial markets are important factors for enforcement of IAS/IFRS in France. Mandatory adoption of IAS/IFRS has decreased earnings management level for companies with good corporate governance and those that depend on foreign financial markets.     

Big data tools for Islamic financial analysis

Behavioural science states that emotions, principles and the manner of thinking can affect the behaviour of individuals and even investors in their decision making on financial markets. In this paper, we have tried to measure the investor sentiment by three means of big data. The first is based on a search query of a list of words related to Islamic context. The second is inferred from the engagement degree on social media. The last measure of sentiment is built, based on the Twitter API classified into positive and negative directions by a machine learning algorithm based on the naive Bayes method. Then, we investigate whether these sensations and emotions have an impact on the market sentiment and the price fluctuations by means of a vector autoregression model and Granger causality analysis. In the final step, we apply the agent‐based simulation by means of the sequential Monte Carlo method with the control of our Twitter measure on Islamic index returns. We show, then, that the three social media sentiment measures present a remarkable impact on the contemporaneous and lagged returns of the different Islamic assets studied. We also give an estimation of the parameters of the latent variables relative to the agent model studied.     

Edge Cities and the Viability of Metropolitan Economies: Contributions to Flexibility and External Linkages by New Urban Service Environments

Economists have had little to say concerning the impact of Edge Cities in metropolitan complexes, much less about how they relate to the economy in general. The present paper is aimed at those concerns. It begins with a general overview of the Edge City concept as put forward by Joel Garreau. Following that it discusses metropolitan change in a pre-Edge City format. It then considers Edge Cities in the context of growth poles and discusses their role in providing economic linkages that facilitate change. The intent is to provide a better understanding of the impact of Edge Cities upon host metropolitan areas and the economy at large.     

A model of optimal portfolio selection under liquidity risk and price impact

We study a financial model with one risk-free and one risky asset subject to liquidity risk and price impact. In this market, an investor may transfer funds between the two assets at any discrete time. Each purchase or sale policy decision affects the rice of the risky asset and incurs some fixed transaction cost. The objective is to maximize the expected utility from terminal liquidation value over a finite horizon and subject to a solvency constraint. This is formulated as an impulse control problem under state constraints and we characterize the value function as the unique constrained viscosity solution to the associated quasi-variational Hamilton–Jacobi–Bellman inequality. We would like to thank Mihail Zervos for useful discussions.     

FDI inflows,economic growth,and governance quality trilogy in developing countries: A panel VAR analysis

This study provides evidence of the triangular relationship between governance quality, foreign direct investment, and economic growth. Unlike previous studies in the governance—foreign direct investment—growth literature, this study employed the panel vector autoregressive model to examine the impact of governance quality and foreign direct investment on economic growth. Moreover, we used the impulse response function tool, which was developed in the same context, to better understand the reaction of the two main variables of interest, foreign direct investment, and economic growth, after shocks to the governance quality variable. Finally, the analysis was completed by the variance decomposition of all variables. These analyses were conducted for 102 developing countries from 1996 to 2014. Overall, the results show that inward foreign direct investment has a significant impact and can strongly encourage economic growth. These results indicate that the quality of governance in developing countries does not affect foreign direct investment and economic growth.     

Former auditors on the audit committee and earnings management: Evidence from African banks

This paper investigates whether former auditors on the audit committee constrain earnings management through loan loss provisions. Based on an analysis of the annual reports of 82 African listed banks over the period 2011–2016, findings show that the presence of former auditors on an audit committee is associated with lower earnings management. This result suggests that audit committee members with auditing expertise and background contribute to effective monitoring of management’s accounting practices. Furthermore, results reveal that the reducing effect on earnings management of former auditors is strongest for directors who are unaffiliated with the bank’s current external auditor.
