Question: 11.2 Suppose the production function for widgets is given by q = KL- .8K 2 - .IV, where q represents the annual quantity of widgets
11.2 Suppose the production function for widgets is given by q = KL- .8K 2
- .IV, where q represents the annual quantity of widgets produced, K represents annual capital input, and L represents annual labor input.
a. Suppose Kâ 10; graph the total and average productivity of labor curves. At what level of labor input does this average productivity reach a maximum? How many widgets are produced at that point?
b. Again assuming that K= 10, graph the MPL curve. At what level of labor input does MPL = 0?
c. Suppose capital inputs were increased to K â 20. How would your answers to parts (a)
and
(b) change?
d. Does the widget production function exhibit constant, increasing, or decreasing returns to scale?
