Priyanka's company has the production function Q=100K^0.5L^0.5, where Q measures output, K measures machine hours, and L measures labor hours. Suppose that the rental rate of capital is R=$30, the wage rate is W=$15, and the firm wants to produce 5,000units of output. Use the Lagrange method to find the optimal input mix. What the optimal level of K & L?
Lagrangean problem can be set up as min 15L + 30K subject to the constraint 100√(KL) = 5000 , where 15L + 30K is the cost function .
Now, pitting this in the third FOC, 5000 = 100√(KL)
==> 5000 = 100 √(K(2K)) ==> √(2K2) = 50 ==> 2K2 = 2500
==> K2 = 1250 ==> K = 35.36
==> l = 2(35.36) = 70.72

Tiffany's company has the production function Q=2K^0.5L^0.5, where Q measures output, K measures machine hours, and L measures labor hours. Let the wage rate be W, and suppose that the rental rate of capital is R=$20 and the firm wants to produce 400 units of output. Use the Lagrange method to find the demand curve for labor as a function of the wage rate. Your answer will have L on the left hand side of the equation. On the right...
Aamir's company has the production function Q=8K^0.75L^0.25, where Q measures output, K measures machine hours, and L measures labor hours. Suppose that the rental rate of capital is R=$120, the wage rate is W=$20, and the firm wants to produce 800 units of output. Use the Lagrange method to find the optimal input mix. What the optimal level of K?
A firm has a production function of Q=20K^.2*L^.8 where Q measures output, K represents machine hours, and L measures labor hours. If the rental cost of capital (r) equals $15 the wage rate (w) equals $10, and the firm wants to produce 40,000 units of output, how much labor and capital should the firm use?
A firm produces output according to the production function: Q = F(K,L) = 2K + 2L. a. How much output is produced when K = 2 and L = 3? b. If the wage rate is $65 per hour and the rental rate on capital is $35 per hour, what is the cost-minimizing input mix for producing 4 units of output? Capital: Labor:
A firm’s production technology is given by the production function q = 0.25 LK where L represents labor hours, K machine hours and q the amount of output. The market wage and rental rates are, w= $16 and r = $256. The firm is operating in the long run where it can adjust both inputs. (a) Suppose that the firm currently is using ten labor hours for each machine hour. Is it minimizing its long run total cost? If so...
2) Consider the following production function for shirts: q=13/4K1/4, where L is worker-hours, and K is sewing machine-hours. The cost of one hour of labor L is w The cost of renting a sewing machine for one hour is r. What type of returns to scale does this production function have? a) b) Compute the marginal product of labor L and marginal product of capital K. What is the marginal rate of technical substitution of labor for capital .e. how...
(20 points) A firm's production function is q = 10.5K0.5, so that MPL = 0.5 0.5 40.5 20.5 and MPK = 0.5 0.5 10.5 k. Labor (L) costs w = 1, and capital (K) costs r = 4. a. (5 points) Solve for the long run optimal amount of labor (L') and capital (K*) if the firm wants to produce exactly 96 units of output. b. (5 points) What is the firm's long run total cost (in dollars) of producing...
9. A firm produces output according to a production function Q = F(K,L) min [2K,4L]. a. How much output is produced when K-2 and L = 3? b. If the wage rate is $30 per hour and the rental rate on capital is $10 per hour, what is the cost-minimizing input mix for producing 4 units of output? How does your answer to part b change if the wage rate decreases to $10 per hour but the rental rate on...
A textile company has the production function Q = min{0.25K, 0.5L}, where K is units of capital and L is hours of labor. a. Without any warning, the price of capital doubles. What should this textile company do in response? b. If this textile company were planning a new plant, would there be any advantages to a larger facility?
The production function for widgets takes the following form: q = 4L + 6K a. What is the least cost combination of L and K that the firm should employ to produce 48 widgets when w = 2 and r = 4. b. Suppose the price of labor increases to w = 4 but the rental rate of capital is unchanged. If the firm still wants to produce 48 widgets at the lowest cost possible, should it alter its input...
