收入上的分类匹配
Assortative Matching on Income
摘要
We analyze marital matching on income using an extremely rich Dutch data set containing all income tax files over seven years. We develop a novel methodology that directly extends previous contributions to allow for highly flexible matching patterns. Investigating all marriages that took place between 2013 and 2019, we find that marital patterns are particularly intriguing. While a majority of couples match assortatively, a small but significant minority display negative assortative matching. We also show that standard approaches, which consider all married couples using current incomes (as opposed to pre‐marriage incomes used in our approach), may generate misleading conclusions.
中文摘要
我们利用一份极为丰富的荷兰数据集，该数据集包含七年内所有所得税档案，对收入层面的婚姻匹配进行了分析。我们开发了一种新颖的方法论，直接扩展了先前的研究贡献，以允许高度灵活的匹配模式。通过考察2013年至2019年间发生的所有婚姻，我们发现婚姻模式尤为引人注目。尽管大多数夫妻呈现同型匹配，但少数但显著的群体表现出负向同型匹配。我们还表明，采用标准方法（即考虑所有已婚夫妇的当前收入，而非我们方法中使用的婚前收入）可能会得出误导性结论。
