Corrigendum: Sex Selection and Gender Balance

摘要

In my paper, "Sex Selection and Gender Balance" published in the February 2011 issue of the American Economic Journal: Microeconomics, I presented estimates of the extent of marriage market imbalance in China and India (see Table 1, 266). Unfortunately, the estimates for India were incorrect, due to an error in computing the rate of growth of cohort size. Table 1 here reports the correct figures for India, based on the population in the age group 0-6 in the 2001 census, and projecting to the marriage market situation facing these cohorts in the future. Cohort sizes are growing slowly in the country as a whole. Given the age gap at marriage, this implies that one needs 103.6 boys per 100 girls for marriage market balance. Since the actual number of boys per 100 girls is 107.8, there is an excess of 4.2 boys per 100 girls.
