The Conventional Analysis
• Wage rate increases with binding constraint• Increase in the quantity supplied of labor• Decrease in the quantity demanded• Fall in employment rate; Increase in unemployment rate• Increase in costs of production for affected industries• Increase in prices paid by consumers• More elastic demand for labor, the greater the fall in
employment

Criticisms of Card and Krueger
Their data is fatally flawed.They focus only on short term effects.
Employers may be slow to adjust to higher minimum wage.
Consumers may substitute between more expensive restaurant food and fast food. The increase in demand would offset the effects of higher minimum wage.

What Do We Know?
Effects on teenage employment, if negative, are small
Studies suggest the effect is smaller today than 15-20 years ago.
School enrollment decreases as minimum wage increases.

Reconciling Results with Theory
Data is wrong Minimum Wage not binding Labor Markets are not competitive Labor supply and demand not measured in quality units.

The Minimum Wage and Poverty
With no employment consequences, increase in minimum wage increases incomes of minimum wage workers.
Not all minimum wage workers are poor.Estimated impact on poverty rate is small.
