The last point of the executive summary of this makes that point.What data shows this to be the case?
Section 3.3 states;
3.3 THE EFFECT OF THE MINIMUM WAGE CHANGE ON HOUSEHOLD INCOME Figure 3.7 indicates that the 2016 minimum wage increase had little effect on the gross household income distribution, using either measure of income. The minimum wage effect oscillates around zero and is not statistically significant at any point of the annual equivalised gross income distribution. The effect is also close to zero for most of the equivalised monthly gross employment income distribution (ranging from €0 to €5,000 per month) although a small, positive and marginally statistically significant effect is observed at one point (€800 per month).20 Therefore, there is no strong evidence to indicate that the increase in the minimum wage impacted household income. While we observe strong effects when looking at the hourly wage distribution of individual employees, the fact that minimum wage workers are located along the entire household income distribution, and are typically not primary earners within households, means that these effects do not translate into household income. This is in line with some of the recent literature on the relationship between the level of the minimum wage and income inequality (Logue and Callan, 2016; MaCurdy, 2015; Caliendo et al., 2017).
If we want to reduce poverty then have a more graduated reduction in welfare supports. Increasing the minimum wage has little or no impact on poverty.
