Question
2. Indira runs a bakery using labor (L, measured in hours of her time) and capital (K, measured
in ovens). Indira's production function (measured in loaves of bread) is given by
f (L, K) = 4L}K³.
(a) Indira currently has 8 ovens.
i. Find an expression for her (short-run) average and marginal product of labor.
ii. In two separate diagrams, graph Indira's total, average, and marginal product of
labor. Do these curves follow all the rules we discussed about the relationships
between curves? Does Indira's production technology satisfy the law of diminishing
marginal returns?
(b) Suppose Indira is trying to decide whether to buy more ovens or sell some of the ones she
has and wants to understand the tradeoffs between more ovens and her time. If Indira
wants to produce 100 loaves a week, help her find out how many ovens she’ll need for
various amounts of her time. That is, find an expression for the number of ovens she'll
need to produce 100 loaves as a function of the number of hours she works. (Hint: if
re stuck, trying picking a couple specific numbers of hours she might work and see
how many ovens she’d need to get 100 loaves. Then try to generalize to get an expression
that will work for any amount of time. ).
(c) Plot your equation from part (b). What does this line represent?
(d) Find an expression for Indira's marginal rate of technical substitution between ovens
and labor as a function of K and L. What is the connection between your answer to
this question and the picture you drew in part (c).
