The study describes the patterns of concurrent wasting and stunting (WaSt) among children age 6–59 months living in the 1980s in Niakhar, a rural area of Senegal under demographic surveillance. Wasting and stunting were defined by z scores lower than −2 in weight for height and height for age. Both conditions were found to be highly […]

Objective To investigate whether children with concurrent wasting and stunting require therapeutic feeding and to better understand whether multiple diagnostic criteria are needed to identify children with a high risk of death and in need of treatment. Design Community-based cohort study, following 5751 children through time. Each child was visited up to four times at […]

The recent deployment of fibre-optic submarine cables (SMCs) in sub-Saharan Africa (SSA) raised the prospects for the digital economy expansion and the whole sub-continent take-off, but also exposed countries and populations to new sources of vulnerability. This paper provides empirical evidence on the ambivalent effect of SMC deployment on the digital divide in 46 SSA […]

Dans un article célèbre, Gordon (2012) souligne que l’impact de la troisième révolution industrielle, marquée par la pénétration des ordinateurs, de l’Internet et des téléphones portables, sur la productivité du travail et sur l’emploi aux États-Unis est très limité par rapport à celui de la première révolution industrielle (caractérisée par l’invention et le développement des […]

This paper is the first product of a project which aims to build a Collaborative Smart Mapping of Mini-grid Action (CoSMMA), whose principal objective is to identify best practice in decentralized electrification projects. By evaluation of 421 projects, from published research papers, we have built a pilot CoSMMA which proves its feasibility. Its relevance is […]

Fondé en 1962 en zone rurale à 150 km de Dakar, l’observatoire de Niakhar est le plus ancien observatoire de population en Afrique encore en activité. Au coeur d’une histoire scientifique et humaine originale, il a permis d’assurer le suivi sanitaire, démographique, social, économique et environnemental de plus de deux générations. En revisitant 50 années […]

This paper reviews integration among the eight African Regional Economic Communities by comparing their characteristics and progress with three other South–South Regional Integration Arrangements.  Three conclusions emerge: (i) slow progress towards meeting overly ambitious objectives; (ii) small changes in the destination of trade across all Regional Economic Communities, indicative of persistent high trade costs and […]

We develop a dynamic model of the world economy that jointly endogenizes individual decisions about fertility, education and migration. We then use it to compare the short- and long-term effects of immigration restrictions on the world distribution of income. Our calibration strategy replicates the economic and demographic characteristics of the world, and allows us to […]
