Just wage and just working conditions have always occupied a central position in Catholic social ethics. The social teaching of the Catholic Church has however preoccupied itself for a long time with the employment relationships in the formal economy. Consequently, the self-employment and the other individual economic activities in the informal economy, highly important in developing countries, have until now not been ethically reflected upon. In this excellent study, the author takes the Nigerian situation as a point of departure from which he offers new opportunities for developing a poverty alleviation strategy that aims, above all, at creating Decent Work opportunities in the informal economy. This is indeed an excellent contribution not only to the further development of the Catholic social ethics for the African context but also to the current efforts in the continent at reducing poverty in a sustainable way .
