Consider two firms that produce a single output good, y, using two inputs: Capital, K, and labor, L. the prices of each unit of capital and labor are r and w, The output good y sells for $p per unit. Firm A’s production function is y = fA(K,L) = K1/4 L1/4. The profit function is thus: ðA(K,L) = K1/4 L1/4 – rK -wL   Find the profit maximizing levels of K and L as functions of r, w, and p. Suppose that r = w = $1 and p = $4. What is the profit maximizing level of output, y ?

Problem #1

 

  1. Consider two firms that produce a single output good, y, using two inputs: Capital, K, and labor, L. the prices of each unit of capital and labor are r and w, The output good y sells for $p per unit.

Firm A’s production function is y = fA(K,L) = K1/4 L1/4. The profit function is thus:

ðA(K,L) = K1/4 L1/4 rK -wL

 

  1. Find the profit maximizing levels of K and L as functions of r, w, and p.
  2. Suppose that r = w = $1 and p = $4. What is the profit maximizing level of output, y ?
