Suppose the marginal product of labor is given by MPL = 200 - 0.5L where L is aggregate employment. The aggregate quantity of labor supplied is 300 + 8w. where w is the real wage. If a supply shock increases the marginal product of labor by 10 (to MPL = 210 - 0.5 L), 1. By how much does the real wage increase? Show all your work in the space below. (4 points) 2. By how much does employment increase? Show all your work in the space below. (4 points)
