Renewable energy deployment in the MENA region:Does innovation matter?

This paper contributes to the renewable energy literature from two perspectives. First, we investigate the factors driving renewable energy deployment in the MENA countries using economic, financial, and political variables including financial development, government effectiveness and political stability. This investigation is empirically carried out by the Panel Smooth Transition Model (PSTR) (Gonzales et al., 2017) that explicitly explores the threshold effect within the determinants of renewable energy production. Second, we introduce innovation as a new determinant of renewable energy deployment to account for the mediating role of technological innovation in the achievement of SDGs and especially the SDG7. Using two proxies of innovation (i.e. ICT and percentage of internet users), we show that higher innovation performance is likely to increase the impact of governance quality on renewable energy deployment. Therefore, governance quality, innovation, political stability, and financial development are the main drivers of renewable energy deployment. The paper calls for sustainable policy options that increase innovation performance and governance quality to increase the production of renewable energy

Delayed payment of residential water invoice and sustainability of water demand management

This paper investigates empirically the reasons for delays in the payment of clean water invoice in Algeria. Using a data set of 27,363 households connected to the water services network and a small-sample survey of 172 household, we estimate several duration models to better understand the main determinants of water invoice time to payment. The delayed payment of water bills could be explained by three determinants: the household financial constraints, the quality of the public service provided, and disincentives through increasing water tariff structure, which is used to manage sustainably the demand for water. This study calls for a modification in the tariff structure to promote equity and water resource protection. It also suggests providing additional efforts to improve the quality of the public water service offered

Dans les brumes de l'endogénéité. Une étude critique des relations entre performance sociétale et performance économique

International audienceManagers engage in CSR practices improvement strategies, not randomly, but takinginto account the anticipation of the marginal financial impact of these strategic decisions. The purpose of this article is to raise awareness among researchers, in the field of social issues in management, about endogeneity bias that plagued the econometric models used so far. This article offers an approach for understanding endogeneity bias in studies based on panel data models. It presents statistical demonstrations of possible sources of endogeneity (i.e., omissions of variables, simultaneity, measurement errors), and provides an overview of the most commonly used econometric methods to overcome them. Finally, this article shows the superiority of the Generalized Method of Moments (GMM) in the case of studies based on panel data.Les décisions managériales relatives à l’amélioration des pratiques RSE ne sont pas aléatoires. Elles sont endogènes à l’anticipation de l’impact financier marginal de ces pratiques. L’objectif de cet article est de sensibiliser les chercheurs dans le domaine des problématiques sociétales en management au biais d’endogénéité qui entache nombre de modèles économétriques utilisés jusqu’à présent. Cet essai méthodologique propose une démarche destinée à déceler et décrypter le biais d’endogénéité tel qu’il se glisse dans bien des études sur données de panel. L’article présente des démonstrations statistiques des sources potentielles d’endogénéité (i.e., omissions de variables, simultanéité, erreurs de mesures), et fournit un aperçu des méthodes économétriques les plus utilisées pour y pallier. Enfin, il montre la supériorité de la méthode des moments généralisés (GMM) dans le cas des études basées sur des données de panel

Two Lip Carcinomas following Allogeneic Hematopoietic Stem Cell Transplantation: A Case Report and Literature Review

Background. Secondary solid cancers are severe complications in patients who have undergone allogeneic hematopoietic stem cell transplantation (AHSCT) for malignant and nonmalignant lymphohematopoietic diseases. Objective. The aim of this work was to report a case of two lip carcinomas following AHSCT and to warn doctors about the importance of regular check-ups of patients who have received HSCT. Observation. A 57-year-old man was referred by the dermatology department for the management of exophytic budding lesions on the lower lip evolving since 5 months. The patient was in complete remission following allogeneic bone marrow transplantation for acute myeloid leukemia since five years. Clinical and histological findings confirmed the diagnosis of a squamous cell carcinoma of the two lesions. Conclusion. It is of paramount importance to seek an oral squamous cell carcinoma in the presence of persistent lesions in HSCT recipients
