AbstractThis study analyzes the intergenerational transmission of education in nine Sub‐Saharan African countries, using nationally representative household survey data on parents of adult individuals. It provides the levels and trends of intergenerational persistence of years of schooling over 50 years, and it also ranks the nine countries relative to other nations. There is a declining cohort trend in the intergenerational persistence of education, particularly after the 1960s. Nevertheless, the education of parents remains a strong determinant of the educational outcomes of children. The analysis also documents country heterogeneity (intergenerational educational mobility varies significantly across countries) and a marked gender effect: daughter's education attainment is more correlated with her parents' education than that of sons. From a policy perspective, our result points to the importance of targeted redistributive policies and the expansion of secondary education to improve mobility.

We build an economico-epidemiological Solow-Swan model. Mortality and morbidity effects on effective labor are taken into account. A Ben-Porath-like mechanism affects the dynamics of the saving rate and reduces labor productivity. Based on optimal projections of the demographic and economic South African series on the period 2000-2050, we identify a delayed effect of HIV/AIDS on economic growth: the growth rate gap between the AIDS and no-AIDS scenarios is rather stable between 2010 and 2020, but then it increases sharply between 2020 and 2030, keeps increasing at a much lower pace between 2030 and 2040, and finally stabilizes after 2040. The fall in active population is the main factor behind AIDS impact on economic growth during the decade 2020-2030 while the Ben-Porath mechanism on labor productivity is more relevant in the last decade. Physical capital accumulation plays a minor role.

We study dynamics of interactions among economic growth, population, and environmental quality when stochastic shocks in these systems display long‐memory property. We make two important contributions. First, we show that the long‐memory persistence in economic growth is determined jointly by the convergence speed of shocks in both environmental quality and population. Second, by simulating a modified Solow‐Swan economy we demonstrate that the convergence‐speed of shocks in these systems significantly affects the long‐run growth trajectory of output. Our empirical examination evince that adjustment of output to long‐run equilibrium is very slow, thanks to the slowly dissipating population and pollution shocks.

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
