This investigation will help students examine issues related to the minimum wage, including: What does economic theory suggest will result in minimum-wage earnings and employment if the minimum wage is increased? Does an increase in the minimum wage increase the income of young workers? And, does an increase in the minimum wage decrease the employment opportunities for young workers? After the investigation, students will be able to use supply/demand analysis to evaluate the impact of raising the minimum wage, and explain why it is difficult to produce conclusive evidence about the impact of raising the minimum wage. (Note: Data in the investigation may be out of date, and teachers may wish to update it for students.)
