Is a minimum wage an appropriate instrument for redistribution?

We analyze the redistributive (dis)advantages of a minimum wage over income taxation in competitive labor markets. A minimum wage causes more unemployment, but also leads to more skill formation as unemployment is concentrated on low-skilled workers. A simple condition based on three sufficient statistics shows that a minimum wage is desirable if the social welfare gains of more skill formation outweigh the social welfare losses of increased unemployment. Using a highly conservative calibration, a minimum wage decrease is shown to be part of a Pareto-improving policy reform for all countries under consideration, except possibly the United States.
