The econometric results are based on a cross-regional analysis of before/after changes in wages, hours, and jobs, and they generally support the proposition that the introduction of minimum wages caused average wages to rise, and hours of work and total employment to fall. For women, the minimum wage appeared to have no effect on employment in Year 1, but a significant negative effect in Year 2. For men, whose employment rose over time, there is nonetheless a detectable negative effect of the minimum wage, which also appeared to have been stronger in the second year than the first.
