Persistence Of Income Inequality: Does Child Mortality Matter?

In: The journal of developing areas, Band 46, Heft 2, S. 105-123

Abstract

Many developing countries are afflicted by persistent inequality in the distribution of income. While a growing body of literature emphasize differential fertility as a channel through which income inequality persists, this paper investigates differential child mortality - differences in the incidence of child mortality across socioeconomic groups - as a critical link in this regard. Using evidence from cross-country data to evaluate this linkage, we find that differential child mortality serves as a stronger channel than differential fertility in the transmission of income inequality over time. We use random effects and generalized estimating equations techniques to account for temporal correlation within countries. The results are robust to the use of an alternate definition of fertility that reflects parental preference for children instead of realized fertility.
