Education, Poverty and Child Labour

The purpose of the paper is to investigate the effects of poverty and educational policies on school attendance, child labour and growth. We consider an OLG model, with parental educational choices. It is assumed there is a trade off between child labour and human capital accumulation. If parents don't choose for quality of education, it is shown that a poverty trap may occur in the presence of a consumption subsistence or when the quality of education is inadequate. A private education system, where schooling quality is endogeneized can improve growth and reduce child labour, and cycles may occur. A public education system does not generate cycles, but it can generate more easely a poverty trap. In this case, only subsidies would help to reduce poverty and, consequently, child laboueducation, child labour, consumption subsistence, growth, educational policies

Periodic orbits of a seasonal SIS epidemic model with migration

We consider a seasonally forced SIS epidemic model where the population is spatially divided into two patches. We consider that periodicity occurs in the contact rates by switching between two levels. The epidemic dynamics are described by a switched system. We prove the existence of an invariant domain D containing at least one periodic solution. By considering small migrations, we rewrite the SIS model as a slow-fast dynamical system and show that it has a harmonic periodic solution which lies in a small tubular neighborhood of a curve . We deduce from this study the persistence or not of the disease in each patch
