总结。本文提出了一种估计政策变化对结果分布的影响的方法，该方法使用比较分位数而不是控制组，并提供了估计估计量的方差的方法。这项经验分析给出了在各种反事实的分配变化假设下，对英国最低工资上调的“溢出”效应的估计，即对那些已经超过最低工资的人的工资的影响。证据是针对一个简单的反事实提出的。根据拟议的反事实估计，溢出效应很小，在大多数情况下不会超过第五个百分位数。
Summary. The paper presents a method for estimating the effects of a policy change on an outcome distribution that uses a comparator quantile rather than a control group and provides methods for estimating the variances of the estimators. The empirical analysis presents estimates of ‘spillover’ effects of increases in the UK minimum wage, i.e. effects on the wages of those who are already above the minimum, under various counterfactual distribution shift assumptions. Evidence is presented against a simple scaled counterfactual. On the basis of the proposed counterfactual estimated spillover effects are small and in most cases do not reach above the fifth percentile.
