There has been a great deal of discussion in the news over the past few years about raising the minimum wage. Some cities and states have increased minimum wages in their locality above the federal minimum wage, which has brought demands for the federal minimum wage to be increased. Some argue that the federal minimum wage should be increased to $10.10 while others argue for the $15 level. From a microeconomics perspective, who is hurt and who is helped by an increase in the legal minimum wage? Why might a higher minimum wage increase unemployment? Under what circumstances might a higher minimum not impact unemployment?
