3. Suppose a firm competing in a perfectly competitve market uses machines (K) and workers (L) to produce containers of nails. Their production technology is given by q = (K)3 (L)3 . Suppose the firm already has 27 machines, the cost of people is w = $12 and each container of nails sell for P = $12.

(a) Set up the firm’s problem. What time frame is being examined here? How many workers does the firm hire? How much does the firm produce? (All the numbers here are whole numbers)

(b) Suppose the firm has profits equal to zero, what else can you say about the time frame? What value would r take for this to be true?

(c) Suppose a new method of producing machines makes the rental rate of capital r = 24, how many machines (K) and workers (L) will the company want when able to adjust both if they do not want to adjust their quantity? Make sure to set up the firms problem correctly. Sketch the solution using the isoquant and isocosts.
