The Factor Market signals both Workers and Individual Firmsthe price of labor & the wage of labor. The signals indicate P* to both.Based on its revenue/worker(mrp) vs. its costs(mrc) firms determine how many workers to hire (mrp=mrc). Based on their Marginal Benefit vs. Marginal Cost workers determine whether or not they will work for this wage (msc=msb).
