Culture capital humain et croissance économique

In this paper , we consider an economic growth model with human capital accumulation , positive externalities and a cultural system of social norms . We show that endogenous rational emergence of this cultural belief may lead to increasing the stock of human capital and hence accelerating national growth.The mechanism of this internalization is based on the existence of endogenous social status or identity pattern that encourages the accumulation of knowledge. This cultural norm is presented as an informal mechanism or informal institution which may be an effective substitute tool to a the formal institution given by a system of income taxation.
