This paper uses data from 10 countries of the African franc zone from 1996 to 2017, to gauge the effect of external debt on industrialization in the presence of non-linearity. Our analyzes are done based on two aspects. Firstly, using a Panel Smooth Transition Regression (PSTR), our results show that there is a non-linear relationship between external debt and industrialization in the African franc zone, which depends on the level of the external debt stock, the threshold is $58.91 \%$ of GDP. While before this threshold, external debt has no direct effect on industrialization, after this threshold it is harmful to it. Secondly, an analysis in two periods (1996-2006 and 2007-2017) by the GLS and SUR methods shows that before 2006, the external debt was an asset for industrialization but after, it gave way to domestic credit. Thus, the external debt has become obsolete after reaching the completion point of the HIPC initiative, and would be a danger for the industrialization of the franc zone in the event of excess.
This paper aims at highlighting the inequality aversion of the Cameroonian social planer. This is allowed by the multilevel (α, β)-decomposition of the α-Gini which integrate in its functional form a parameter of inequality aversion of the decision maker being related either to within-group inequality (α) or between-group inequality (β). Analysis are carried out by sex groups on data from the third and the fourth Cameroonian Survey on households. It's appear that the overall inequality index decrease between 2001 and 2007. The Cameroonian social planer appears sensitive to both within group and between group households' inequalities following decomposition by sex.
L’objectif de cet article est d’analyser les effets de la consommation d’énergie fossile sur la croissance économique et sur l’environnement dans 14 pays de l’Afrique Subsaharienne1, de 1970 à 2015. A partir d’un modèle vectoriel à correction d’erreur (VECM), les résultats montrent qu’il existe une relation de causalité en panel au sens de Granger, allant de la consommation d’énergie vers la croissance, et une autre allant de la consommation d’énergie vers les émissions de co2. Nous recommandons aux décideurs de mettre sur pied des politiques d’industrialisation et de protection de l’environnement.
