6. Conclusions
The purpose of this paper was to investigate the link between globalization, defined as increase in trade openness and penetration of FDI, and incidence of child labour, while taking into account the role of credit market imperfections. The empirical assessment was based on the cross-sectional analysis of 129 developing countries for four decades, from 1970 to 2010. This study showed that income does affect child labour. The only difference in this study and all the previous studies is that it predicts the negative effect of income using two different measures of income after correcting endogeneity bias. To the best of the author’s knowledge, these measures have not been incorporated in earlier studies at the cross-sectional level.
The study first estimated the effect of income on child labour incidence by using real GDP per capita, and then estimated the effect by using an alternative measure of income: income held by bottom quartile of the population. This proxy helps in understanding the income inequality argument. This argument was tested by comparing the estimates of different proxies of income. The two alternative measures, real GDP per capita and income held by bottom quartile of the population showed a significant but non-linear effect. The study also concludes that the income of the bottom quartile of the population rather than real GDP per capita is the better income proxy to use when analysing child labour incidence. As this measure is based on Gini coefficient and income share of bottom quartile population, the study further concludes that an effective policy to reduce child labour incidence should also take into account inequality that exists in an economy.
