Cet article étudie la relation entre consommation d'énergie par habitant et revenu par habitant, ainsi que les déterminants de cette relation, sur un échantillon de données de panel de 29 pays d'Afrique subsaharienne observés sur la période 1980-2011. Notre spécificité est la prise en compte explicite de l'hétérogénéité entre pays à l'aide d'un modèle de données de panel à coefficients hétérogènes. Les résultats montrent que la relation énergie-revenu est effectivement très hétérogène et que la courbe de Kuznets environnementale existe dans seulement quatre pays. Cette hétérogénéité est également observée dans les effets des variables affectant cette relation. Classification JEL : C23, O55, Q40

À l'aide d'une modélisation non paramétrique structurelle, nous montrons que les émissions de co 2 augmentent clairement avec le revenu pour de faibles niveaux de revenus. Cette relation est décroissante bien que non significative pour des niveaux de revenu élevés. Nous observons également que les émissions de co 2 augmentent de manière monotone, mais à un taux décroissant, avec la consommation d'énergie. Classification JEL : C14, O13

International audience ; This paper aims to determine an optimal allocation of the European Cohesion Fund (ECF) and compares it with the observed allocation. This optimal allocation is the solution of a donor optimization problem which maximizes recipient countries' GDP per capita to achieve economic convergence in the European Union. Compared to the observed allocation, our solution can identify the recipient countries that can benefit from higher ECF transfers than the observed levels, as those having low relative GDP per capita, large population size and where the ECF has a strong capacity to support economic growth. Result is robust to changes in the specification of the donor's utility function.

International audience ; We propose a structural approach to investigate total factor productivity (TFP) and economic growth of 58 provinces and municipalities of Vietnam (known as one of the most dynamic emerging economies in the last few years). The analysis is applied to the provincial data that are available to us for the period 2000–2007. TFP is composed of three components: an autonomous technological change, an observed deterministic part depending on external factors, and an unobserved stochastic part. Estimation results do not show any evidence regarding the impacts of national and local public spending on TFP and economic growth of Vietnam's provinces. On the contrary, human capital and industry share (compared to shares of agriculture and services) significantly increase the provincial TFP, helping to explain the cross-province differences in terms of productivity. Finally, TFP of Vietnam's provinces does not converge in the long run as it displays a polarization feature around two main groups of provinces, a large group with low TFP levels and a much smaller group with high TFP levels. This bipolar pattern of TFP distribution supports the competitiveness disparity among the Vietnam's provinces.
