Journal of Political Economy · 2024 · Jérôme Adda、Paolo Pinotti、Giulia Tura

中文摘要

我们分析合法身份激励对本地人与移民婚姻选择的作用。获得合法身份使移民与本地人通婚的概率降低40%,并使跨族群婚姻的分居风险率提高20%。我们构建并估计了一个关于婚姻、生育和分居的多维均衡模型,其中个体依据可观测和不可观测特征进行匹配。通过允许在文化距离、合法身份和配偶的其他社会经济特征之间进行权衡,我们量化了合法身份的作用和文化偏好的强度,并评估了向移民授予合法身份的福利后果。

Abstract

We analyze the contribution of legal status incentives on the marriage choices of natives and migrants. Access to legal status reduces the probability of immigrants intermarrying with natives by 40% and increases the hazard rate of separation for intermarriages by 20%. We develop and estimate a multidimensional equilibrium model of marriage, fertility, and separation, where individuals match on observed and unobserved characteristics. Allowing for trade-offs between cultural distance, legal status, and other socioeconomic spousal characteristics, we quantify the role of legal status and the strength of cultural preferences and evaluate the welfare consequences of granting legal status to immigrants.
