This paper inquires the effects of globalization on child labor in developing countries via cross-country analysis by decomposing globalization to its components; foreign direct investment (FDI) and trade. The findings reveal that the relationship between the child labor supply and gross domestic product per capita (PCGDP) can be expressed as a U shape. The study indicates that the child labor increases in the developing countries whose PCGDP levels are above $7500 since the net effect of globalization is positive for the positive substitution effect is bigger than the negative income effect. Data have been collected from UNICEF and World Bank.
