Producer surplus measures the benefit to sellers from receiving a price above their costs

What happens to the quantity of labor supplied, the quantity of labor demanded, and the number of unemployed workers if the minimum wage rate set above the equilibrium wage is increased still higher?

What will be an ideal response?
