Question:

Consider the production function

{eq}F(l,K)=3l^{.25}K^{.75} {/eq}

a) Find the cost-minimizing bundle and the long-run total cost if w = 64 and v = 1 and total output = q = 36.

b) Change the price of capital to 3, and the price of labor to 192. Find the cost-minimizing bundle and the long-run total cost.

Constrained Cost Minimization:

Costs can be minimized constrained to the level of output. This occurs when the isocost line is tangent to the isoquant curve. This is where optimal combination of inputs minimizes the costs.

(a).

We set up a cost minimization as the following:

{eq}min\,\,C=64l+k\\s.t\,\,\,3l^{0.25}k^{0.75} {/eq}

Set up a Lagrangian equation:

{eq}Z=64l...
