A Stochastic Dynamic Analysis of Parental Sex Preferences and Fertility
构建了一个随机动态生育模型，证明传统计量检验只能判断是否存在性别偏好，但无法区分是偏好儿子还是女儿，挑战了现有研究中关于儿子偏好检验的有效性。
Formulates a stochastic dynamic model of fertility to evaluate the assumptions that underlie the widely used econometric tests for parental sex preferences. Unlike previous work on dynamic models of fertility, several tractable and testable predictions are established. It is shown rigorously that conventional econometric tests using fertility data are valid tests for sex preferences; however, they cannot separate son preference from daughter preference. The only definite conclusion that one can draw from fertility data is whether there are sex preferences. These results call into question the validity of conventional econometric tests for son preference. -Author
