Book excerpt: Children in poor countries are subjected to exploitation characterized by low wages and long hours of work, as well as by unclean, unhygienic and unsafe working and living conditions, and, more importantly, by deprivation from education, all of which hampers their physical and mental development. Child labour is a complex issue, and clearly it has no simple solution. This book sheds some understanding of its root causes. The book attempts to delve into many of the important theoretical aspects of child labour and suggests policies that could indeed be useful in dealing with the problem under diverse situations using alternative multisector general equilibrium models.
