- The Cobb-Douglas production function is a classic model from economics used to model output as a function of capital and labor. It has the form f(L, C) = CL1C2 where co, C₁, and c₂ are constants. The variable L represents the units of input of labor and the variable C represents the units of input of capital. (a) In this example, assume co = 5, C₁ = 0.25, and C₂ = 0.75. Assume each unit of labor costs $25 and each unit of capital costs $75. With $65,000 available in the budget, develop an optimization model for determining how the budgeted amount should be allocated between capital and labor in order to maximize output. Max s.t. L, C ≥ 0 $ ≤ 65,000 (b) Find the optimal solution to the model you formulated in part (a). What is the optimal solution value (in dollars)? Hint: Put bound constraints on the variables based on the budget constraint. Use L≤ 3,000 and C ≤ 1,000 and use the Multistart option as described in Appendix 8.1.
