With an employment subsidy, the firm’s profits are given by: amount of the subsidy, s. In the top panel of Figure 4.7, the subsidy acts to shift down
the cost function for the firm by reducing its slope. As before, the firm will maximize
profits by choosing the quantity of labor input where the slope of the revenue function is
equal to the slope of the cost function, (t-s), so the firm chooses the quantity of...
