  • For an individual firm, what is the relationship between the wage rate, average cost of labor, and marginal cost of labor?
    All are equal
  • For an individual firm, what does the demand curve represent?
    The MRP curve
  • What condition do firms use to maximize revenue from workers?
    MRP equals marginal cost of labor
  • How do firms make efficient employment decisions in a perfectly competitive labor market?
    Hire where MRP equals wage rate

    Four
