Abstract Regardless of the degree of development of a country, its government’s education policy, including compulsory education and investment in the education sector, can increase household welfare. Besides, in developed and least developed countries, if the duration of compulsory education is sufficiently long, the government can increase economic growth by setting a longer period of compulsory education or investing more in the education sector. Accordingly, public education policy is one way in which poorer countries can catch up with developed countries. Furthermore, except for directly abolishing child labor, the government can use these sorts of policies to address the problem of child labor.
