You manage a plant that mass-produces engines by teams of workers using
assembly machines. The technology is summarized by the production function
\\[q=5 K L\\]
where \(q\) is the number of engines per week, \(K\) is the number of assembly
machines, and \(L\) is the number of labor teams. Each assembly machine rents
for \(r=\$ 10,000\) per week, and each team costs \(w=\$ 5000\) per week. Engine
costs are given by the cost of labor teams and machines, plus \(\$ 2000\) per
engine for raw materials. Your plant has a fixed installation of 5 assembly
machines as part of its design.
a. What is the cost function for your plant-namely, how much would it cost to
produce \(q\) engines? What are average and marginal costs for producing \(q\)
engines? How do average costs vary with output?
b. How many teams are required to produce 250 engines? What is the average
cost per engine?
c. You are asked to make recommendations for the design of a new production
facility. What capital/ labor \((K / L)\) ratio should the new plant accommodate
if it wants to minimize the total cost of producing at any level of output \(q
?\)
