P10.3 Perfectly Competitive Equilibrium. Demand and supply conditions in the perfectly com- petitive market for unskilled labor are as follows:
QD = 150 – 16P (Demand)
QS = 8P (Supply)
where Q is millions of hours of unskilled labor and P is the wage rate per hour.
A. Graph the industry demand and supply curves.
B. Determine the industry equilibrium price/output combination both graphically and alge- braically.
C. Calculate the level of excess supply (unemployment) if the minimum wage is set at $7 per hour.
