In Cameroun, around 18 percent of children aged between 10-14 years old grow up within a sibship extended to host one (or more) foster-child. This proportion is similar in other African countries and in particular West African ones. This paper aims at estimating the effect of foster-children...

The aim of this article is to show the easiness of exploratory graphs achievement with SAS/INSIGHT®, and the "cognitive" power of visual analysis. This visual analysis is part of learning strategy based on an exploratory approach of data. We demonstrate by variations around basic graphs, such...

This paper aims at explaining differences in education among foster-children and between foster and biological children in developing countries. Foster-children whose biological parents are alive may provide old-age support for both their host and biological parents. Therefore foster-children...

In this paper, we provide a theoretical framework for exploring the consequences of neighborhood informational effects - identified as role models - so as to deduce the urban configuration. With this aim, we have developed an overlapping generations model of community formation. When young, an...
