Figure 18-5 The figure shows a particular profit­maximizing, competitive firm's value­of­marginal­product (VMP) curve. On the horizontal axis, L represents the number of workers. The time frame is daily. Figure 18-5 The figure shows a particular profit­maximizing, competitive firm's value­of­marginal­product (VMP)  curve. On the horizontal axis, L represents the number of workers. The time frame is daily.   -Refer to Figure 18-5. Assume that two points on the firm's production function are (L = 2, Q = 180)  and (L = 3, Q = 228) , where L = number of workers and Q = quantity of output. The firm pays its workers $120 per day. The firm's non­labor costs are fixed, and they amount to $250 per day. We can conclude that A)  the firm sells its output for $12 per unit. B)  if the firm is currently employing 2 workers per day, then profit could be increased by $48 per day if a third worker is hired. C)  the marginal cost per unit of output is $2.50 when output is increased from 180 units per day to 228 units per day. D)  the firm's maximum profit occurs when it hires 3 workers per day. -Refer to Figure 18-5.

Consider the labor market for computer programmers. Because of the dot.com boom in the late 1990s, a lot of workers went to school to learn how to write computer code for one of thousands of new dot.com companies. However, when these computer programming students graduated, the dot.com bust took place. The dot.com bust decreased the value of the marginal product of computer programmers. Holding all else equal, what effect did these two circumstances have on the equilibrium wage in the labor market for computer programmers?


A) The equilibrium wage increased.
B) The equilibrium wage decreased.
C) The equilibrium wage did not change.
D) It is not possible to determine what happens to the equilibrium wage.
