【Abstract】 This paper presents a growth model in which education investment shows positive externalities which build up knowledge capital. A prerequisite for these spillovers to take place is that a country devotes time to education. Externalities associated with investment need education to raise the stock of knowledge capital. Furthermore, we demonstrate that in the social optimum model a cou ntry should devote money and time to education in order to improve the whole social optimum and promote economic growth.更多还原
