Sex Selection and Gender Balance
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, s...

متن کاملParental Sex Selection and Gender Balance
We consider a society where parents prefer boys to girls, but also value grandchildren. Parental sex selection results in a biased sex ratio that is socially ine¢ cient, due to a congestion externality in the marriage market. Improvements in selection techniques aggravate the ine¢ ciency. These results are robust to allowing prices in the marriage market, if the market is subject to frictions. ...
متن کاملSex Selective Abortions and Gender Balance
We examine the implications of parental choice regarding the gender of their child in a context where boys are valued more than girls. In the absence of a bride price system, parental choice may reduce gender bias, but has an adverse e¤ect on welfare since it results in a sex ratio that is biased against girls. Bride prices can ensure e¢ cient outcomes with a balanced sex ratio if markets are W...
متن کاملMutation-selection balance, dominance and the maintenance of sex.
A leading hypothesis for the evolutionary function of sex postulates that sex is an adaptation that purges deleterious mutations from the genome, thereby increasing the equilibrium mean fitness of a sexual population relative to its asexual competitor. This hypothesis requires two necessary conditions: first, the mutation rate per genome must be of order one, and, second, multiple mutations wit...
