Gender‐Biased Breastfeeding in Egypt: Examining the Fertility Preference Hypotheses of Jayachandran and Kuziemko (2011)
在埃及检验了Jayachandran和Kuziemko的理论，即重男轻女导致母亲对女婴的母乳喂养存在被动偏见，结果支持该理论，并指出其对发展中国家的政策意义。
Summary Jayachandran and Kuziemko (Why do mothers breastfeed girls less than boys? Evidence and implications for child health in India. Quarterly Journal of Economics 2011; 126 (3): 1485–1538) develop and empirically validate a theory showing son preference in India generates ‘passive’ parental bias against girls in breastfeeding due to gender‐differentiated birth spacing and fertility stopping. I scientifically replicate their empirical exercises to test the validity of the theory in Egypt, where there is also high prevailing son preference, but little research on its implications for child health investments. I additionally examine whether using the exclusive breastfeeding rate as an alternative outcome yields supportive evidence for the theory. I find the theory is strongly supported by empirical results from Egyptian data, bolstering its policy relevance for developing countries besides India. Copyright © 2015 John Wiley & Sons, Ltd.
