Un réexamen de la relation « inflation - croissance économique » dans les pays africains
Get PDFThis paper returns on the non-linearity of the inflation - growth relationship. He estimates the role of the institutional quality appreciated by the independence of the central bank on the non-linearity of the inflation-growth relationship and identifies the optimal inflation rate in the African countries. In this respect, a panel of 53 African countries over the period 1980-2013 is used to make an analysis of regression of panel with progressive threshold (Panel Smooth Threshold Regression: PSTR developed by Gonzalez and al. 2005). A test of robustness is made with the method of moments generalized in system (GMM). Our results confirm the non-linearity of the relation inflation-growth. This non-linearity of the inflation growth relationship is conditioned by the quality of institutions. Countries with a higher quality of institutions experience less severe effects of inflation than countries having a lower quality of institutions. The optimal inflation rate for the African countries depends on the exchange regime. This rate diverges with those found for developed countries as well as for those of many developing countries.Ce papier revient sur la non-linéarité de la relation inflation-croissance. Il évalue le rôle de la qualité institutionnelle appréciée par le degré d\u27indépendance de la banque centrale sur la non-linéarité de la relation inflation-croissance et la détermination du taux d\u27inflation optimal dans les pays africains. A cet égard, un panel des 53 pays africains sur la période 1980-2013 est utilisé pour effectuer une analyse de régression de panel avec seuil progressif (Panel Smooth Threshold Regression -PSTR- développé par Gonzalez et al. 2005). Un test de robustesse est effectué avec la méthode des moments généralisés en système (GMM). Nos résultats confirment la non-linéarité de la relation inflation-croissance. Cette non-linéarité de la relation inflation croissance est conditionnée par la qualité des institutions. Les pays avec une qualité des institutions plus élevée éprouvent des effets moins sévères d\u27inflation que les pays ayant une qualité des institutions inférieure. Le taux d\u27inflation optimal pour les pays africains dépend du régime de change. Ce taux diverge avec ceux trouvés pour les pays développés ainsi que pour ceux de beaucoup de pays en développement
La rente des ressources naturelles et croissance économique en Afrique : Le rôle des canaux de transmission
No full textThe aim of this article is to assess the effects of natural resource rents on economic growth in Africa, based on various transmission channels such as: trade openness, foreign direct investment, institutional quality and human capital. Based on a sample of 44 African economies over the period 2002-2022, we used the Generalized Method of Moments (GMM) developed by (Arellano and Bond, 1991). As main results, natural resource rents do not have a significant direct influence on economic growth in Africa, the relationship between natural resource rents and economic growth is conditioned by trade openness, human capital (education and health), corruption control, political stability and regulatory quality.
Key words: Natural resource rents, Africa, economic growth, transmission channels.
Classification JEL : O22
Paper type: Empirical ResearchCet article vise à évaluer les effets de la rente des ressources naturelles sur la croissance économique en Afrique en s’appuyant sur les différents canaux de transmission comme : l’ouverture commerciale, les investissements directs étrangers, la qualité des institutions, et le capital humain. À partir d’un échantillon de 44 économies africaines sur la 2002-2022, nous avons fait usage de la Méthode des Moments Généralisés (GMM) développée par (Arellano et Bond, 1991). Comme principaux résultats, la rente des ressources naturelles n’a pas une influence directe significative sur la croissance économique en Afrique, la relation entre la rente des ressources naturelles et la croissance économique est conditionnée par l’ouverture commerciale, le capital humain (éducation et santé), la maitrise de la corruption, la stabilité politique et la qualité de la régulation.

Les changements des systèmes de contrôle de gestion des entreprises industrielles au Maroc : Une étude exploratoire
Get PDFInternational audienceThis article aims to study the determinants of changes in management control systems of industrial companies in Morocco. To address this topic, the concepts of management control systems and changes in these systems were defined. Theoretical frameworks and models were utilized, and previous empirical studies were reviewed, contributing to the development of a conceptual research model describing the determinants of these changes. This research refers to two theoretical frameworks, namely the contingent framework and the sociocognitive framework. Additionally, an exploratory study spanning five years (2017-2021) was conducted in the Moroccan context, involving 35 large companies operating in various industrial sectors and located in different cities across Morocco. For the analysis of the collected data, an approach based on exploratory factor analysis was adopted, implementing principal component analysis (PCA) using SPSS software.The results highlight the complementarity of the two theoretical approaches used in developing the model, incorporating variables such as age, size, decentralization, organizational intensity, differentiation strategy, technology, and organizational learning. These identified variables are factors influencing the observed changes in management control systems within the surveyed companies. The exploratory study will be complemented, in a subsequent research phase, by a confirmatory study on an expanded sample to test the research hypotheses. For this purpose, we plan to rely on structural equation modeling, using the PLS method and the Smart PLS software in an upcoming article.The first part of this article presents a literature review showcasing the employed theories (contingency approach and sociocognitive approaches). It highlights previous research and empirical studies that have utilized both theoretical frameworks. The second part introduces the developed conceptual research model, the adopted methodology, the selected sample, and the data collection process. The third part presents the results obtained from the exploratory study conducted with large industrial companies in Morocco, followed by an analysis of these results and the selection of an improved conceptual model.Cet article a pour objectif d’étudier les déterminants des changements des systèmes de contrôle de gestion des entreprises industrielles au Maroc. Pour traiter ce sujet, les concepts de systèmes de contrôle de gestion et des changements de ces systèmes ont été définis, des théories et modèles ont été mobilisées et des études empiriques antérieures réalisées ont été recensées et qui ont servi à élaborer un modèle conceptuel de recherche décrivant les déterminants de ces changements. Cette recherche fait référence à deux cadres théoriques, à savoir le cadre contingent et le cadre sociocognitif. Aussi, une étude exploratoire sur une période de cinq ans (2017-2021) a été réalisée dans le contexte marocain et portant sur 35 grandes entreprises opérant dans diverses branches industrielles et se situant dans différentes villes du Maroc. Pour l'analyse des données collectées, nous avons adopté une approche basée sur l'analyse factorielle exploratoire, mettant en œuvre une analyse par composante principale (ACP) à l'aide du logiciel SPSS.Les résultats obtenus mettent en lumière la complémentarité des deux approches théoriques qui ont servi à l’élaboration du modèle intégrant les variables âge, taille, décentralisation, intensité organisationnelle, stratégie de différenciation, technologies et apprentissage organisationnel. Ces variables identifiées sont des facteurs impactant les changements observés dans les systèmes de contrôle de gestion au sein des entreprises enquêtées. L’étude exploratoire sera complétée, dans une prochaine recherche, par une étude confirmatoire sur un échantillon élargi afin de tester les hypothèses de recherche. Pour cela nous prévoyons de nous baser sur l'approche des équations structurelles, selon la méthode PLS et en utilisant le logiciel Smart PLS dans un article prochain.La première partie de cet article présente une revue de la littérature montrant les théories mobilisées (l'approche contingente et les approches sociocognitives). Elle met en évidence les recherches et études empiriques antérieures ayant eu recours aux deux cadres théoriques. La seconde partie présente le modèle conceptuel de recherche élaboré, la méthodologie adoptée, l'échantillon sélectionné et la collecte des données. La troisième partie présente les résultats obtenus de l'étude exploratoire réalisée auprès de grandes entreprises industrielles au Maroc, et enfin une analyse de ces résultats a été réalisée et un modèle conceptuel amélioré a été retenu
An empirical assessment of the role of trade in services in export diversification in Sub-Saharan Africa
No full textThis paper identifies the dimensions of international trade in services that promote export diversification in an unbalanced panel of 48 countries in Sub-Saharan Africa over the period 1996 - 2020. Using the System-Generalized Method of Moments (GMM), the results show that tourism, services total export, export in transport services, travel services, insurances services, financial services, use of licenses services and other business services promote export diversification in SSA. Governments should improve their business environment and strengthen services sector liberalization to attract more foreign direct investments in services. They should also adopt policies and strategies to develop and orient the services sector towards more efficient and high-value-added services
Trade Policy and African Participation in Global Value Chains: Does Trade Facilitation Matter?
Get PDFThis study offers an empirical appraisal of the contribution of trade facilitation for Sub-Saharan Africa (SSA) countries participation in global value chains. We used new value-added data on a panel of 25 countries over the period 2004-2017. The results using pooled ordinary least squares (OLS) regression and instrumental variable-two-stage least squares (IV-2SLS) estimators reveal that trade facilitation indicators such as physical infrastructure, information and communication technology, and border and transport efficiency support SSA countries' participation in global value chains. More interestingly, these results are robust at the sectoral level, particularly in agriculture, food & beverages, and textiles & clothing sectors for physical infrastructure and ICT, while the business environment is conducive to upstream integration of GVCs in the agriculture and textiles & clothing sectors. These results underscore the increased importance of trade facilitation in the era of global value chains and call for well-targeted sectoral policies to reap the benefits of these GVCs

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
