Suppose that we have perfectly competitive input markets (for both capital and labor) and output markets. Firm "Tropical Juice" produces orange juice which it sells at $6. The input price that the firm faces is an hourly wage of $5 and the rental rate of $2.

Furthermore, the firm currently has a capital stock of 2.

Find the labor demanded by the firm in the short run under the following production technologies.

a) f(k,l) = k0.1l0.9

b) f(k,l) = max{k, 4l(1/2)}

c) Given the answers in part a and b, rewrite both problems as a cost minimization problem and show the labor demanded for the optimal quantity produced is the same.

    Consider a production function Q=Q(K,L)=6K^(1/2)L^(1/3) with K as capital and L as labor input. Let the price per unit of output be P=$0.50, the cost or rental rate per unit of capital be r=$0.10 and let the price (wage rate) of labor be w=$1. a) find the profit max level of K and L and check with second order condition (my answer was L=3.375 and K=1.5) b) Find max profit (I got profit=1.986)
