This isn't news at all. Minimum wage is just a price constraint, and if the supply/demand equilibrium lies above the minimum wage constraint then the optimal solution does not change. Conversely, raising the minimum wage under these circumstances also has virtually no effect on real income. In fact, under these circumstances workers who earn minimum wage are far better served by applying and switching to higher-paying jobs. Minimum wage levels only impacts economies when they are raised to close to the economy's supply/demand equilibrium point. Hence, minimum wage starts to increase unemployment and deflate median wages in recessions when it becomes a legal impediment to job creation.
