The goal of this homework is for you to get practice with
calculating profitable input use. You may consult with classmates
and other sources, but you must write the answers yourself
in your own words.
Brine Freez sells salty ice cream. Their daily production is
given by the function:
Q = 10 + K + 4L + 20KL – K2 – 2L2
Where Q is servings per day, K is capital (set at 1), and L is
labor.
- (10) Describe in words what the production function
equation is saying. Be clear about units of measure. What is the
general shape of this function?
- Using the appropriate data set above,
- (10) Calculate the marginal product of labor and show
in simplest form. (Show work.)
- (10) Explain in your own words what exactly this
marginal product number means (what it is measuring) when L =
2.
- (10) Calculate the number of workers (L) that would
maximize Brine Freez output (Lmax). (Show your work for
partial credit.)
- (5) What is the predicted number of Brine Freez servings that
results from hiring this number of workers (L)?
