Who Benefits from Marriage?*
研究已婚男性工资高于未婚男性的“婚姻溢价”现象，发现该溢价在工资分布中并不稳健：中位数以上由选择效应解释，仅在低工资处存在因果效应，可能源于雇主歧视。
Abstract The phenomenon that married men earn higher average wages than unmarried men – the marriage premium – is well known. However, the robustness of the premium across the wage distribution and the underlying causes of the marriage premium are unclear. Focusing on the entire wage distribution and employing recently developed semi‐non‐parametric tests for quantile treatment effects, our findings cast doubt on the robustness of the premium. We find that the premium is explained by selection above the median, whereas a positive premium is obtained only at very low wages. The causal effect at low wages may be attributable to employer discrimination.
