本文利用双胞胎和对混合兄弟姐妹性别组成的偏好以及这些变量影响的种族差异引起的准实验变异，提供了关于儿童数量/儿童质量权衡的证据。我们的样本包括生育率非常高的群体。我们计量经济学方法的一个创新是将多个工具变量策略的结果并置，捕捉不同范围内生育率对不同类型人群的影响。为了提高精度，我们开发了一个估计，结合不同的工具集在部分重叠的奇偶性特定的子样本。我们的研究结果非常一致，没有证据表明数量-质量权衡。
This article presents evidence on the child-quantity/child-quality trade-off using quasi-experimental variation due to twin births and preferences for a mixed sibling sex composition, as well as ethnic differences in the effects of these variables. Our sample includes groups with very high fertility. An innovation in our econometric approach is the juxtaposition of results from multiple instrumental variables strategies, capturing the effects of fertility over different ranges for different sorts of people. To increase precision, we develop an estimator that combines different instrument sets across partially overlapping parity-specific subsamples. Our results are remarkably consistent in showing no evidence of a quantity-quality trade-off.
