研究表明，生育率通过社交网络传播，并将这种现象归因于社会互动的影响。然而，目前尚不清楚先前的研究结果是否反映了网络伙伴的直接影响或环境和选择因素（例如共享环境和共同背景特征）。本研究使用工具变量来改善社会互动对生育率影响的识别。利用荷兰统计局社会统计数据集系统（SSD）的数据，我们确定了两个网络——工作场所的同事网络和家庭中的兄弟姐妹网络——来研究网络伙伴对个人生育决策的影响。具有随机效应的离散时间事件历史模型为社会互动效应提供了证据，表明同事和兄弟姐妹的生育能力对个人的生育能力有直接影响。此外，同事效应集中在女性与女性的互动中，女性更容易受到兄弟姐妹的影响，无论兄弟姐妹的性别如何。这些结果首次证明了跨越网络边界的溢出效应，表明生育效应不仅通过不同互动领域内的社会关系累积，而且还通过不同互动领域之间的社会关系累积。
Research has indicated that fertility spreads through social networks and attributed this phenomenon to social interaction effects. It remains unclear, however, whether the findings of previous studies reflect the direct influence of network partners or contextual and selection factors, such as shared environment and common background characteristics. The present study uses instrumental variables to improve the identification of social interaction effects on fertility. Using data from the System of social statistical data sets (SSD) of Statistics Netherlands, we identify two networks-the network of colleagues at the workplace and the network of siblings in the family-to examine the influence of network partners on individual fertility decisions. Discrete-time event-history models with random effects provide evidence for social interaction effects, showing that colleagues' and siblings' fertility have direct consequences for an individual's fertility. Moreover, colleague effects are concentrated in female-female interactions, and women are more strongly influenced by their siblings, regardless of siblings' gender. These results are the first to demonstrate spillover effects across network boundaries, suggesting that fertility effects accumulate through social ties not only within but also across different domains of interaction.
