The Employment Effects of the National Minimum Wage
使用双重差分法估计英国1999年引入国家最低工资及后续上调对就业的影响，未发现对任何人口群体的显著负面就业效应。
This paper estimates the employment effects of the introduction of the UK National Minimum Wage in April 1999 and subsequent upratings in 2000 and 2001. It uses a difference-in-differences estimator based on position in the wage distribution. For the upratings an adjusted estimator is also introduced to allow for the possible differential response to the change in the macro employment trend. No significant adverse employment effects are found for any of these events for any of the estimators for any demographic group. Copyright 2004 Royal Economic Society.
