Sex Selection and Gender Balance
نویسنده
چکیده
We model parental sex selection and the equilibrium sex ratio. With intrinsic son preference, sex selection results in a male-biased sex ratio. This is ine¢ cient, due to a marriage market congestion externality. Medical innovations that facilitate selection increase ine¢ ciency. If son preference arises endogenously, due to population growth causing an excess of women on the marriage market, selection may improve welfare. These results are robust to allowing prices or intra-household transfers in a frictional market. We analyze the e¤ects of sex ratio imbalances on parental investments, the e¤ect of fertility on sex selection and concerns for family gender balance.
