Assortative Matching on Income
利用荷兰七年税收数据，提出新方法分析婚姻中的收入匹配模式，发现多数夫妻同型匹配，但少数显著反向匹配，且标准方法可能误导结论。
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.
