Wage Per Hour | Quantity of Workers Demanded | Quantity of Workers Supplied   ---|---|---   $14 | 12,000 | 6,000   $16 | 10,000 | 7,000   $18 | 8,000 | 8,000   $20 | 6,000 | 9,000   $22 | 4,000 | 10,000   $24 | 2,000 | 11,000   Table 14.12    A. What would the equilibrium wage and quantity be in this market if no union existed?   B. Assume that the union has enough negotiating power to raise the wage to $4 per hour higher than it would otherwise be. Is there now excess demand or excess supply of labor?
