This paper investigates possible spillover effects of the UK minimum wage. The halt in the growth in inequality in the lower half of the wage distribution (as measured by the 50:10 percentile ratio) since the mid-1990s, in contrast to the continued inequality growth in the upper half of the distribution, suggests the possibility of a minimum wage effect and spillover effects on wages above the minimum. This paper analyses individual wage changes, using both a difference-in-differences estimator and a specification involving comparisons across minimum wage upratings, and concludes that there have not been minimum wage spillovers. Since the UK minimum wage has always been below the 10 th percentile, this lack of spillovers implies that minimum wage changes have not had an effect on the 50:10 percentile ratio measure of inequality in the lower half of the wage distribution.
