A firm produces its output using only capital and labor.Labor costs $100 per worker per day and capital costs $200 per unit per day. If the marginal product of the last worker employed is 500 and the marginal product of the last unit of capital is 1,000, is the firm employing the cost-minimizing combination of inputs? Explain.
Cost is minimized when (Marginal product of labor / Wage rate) = (Marginal product of capital / Rental rate)
Here,
Marginal product of labor / Wage rate = 500/100 = 5
Marginal product of capital / Rental rate = 1,000/200 = 5
Since (Marginal product of labor / Wage rate) = (Marginal product of capital / Rental rate), firm is employing cost-minimizing input combination.

A firm is using 30 units of capital and 30 units of labor to produce 90 units of output. Capital costs $500 per unit and labor $5,000 per unit. The last unit of capital added 5 units of output, while the last unit of labor added 45 units of output. The firm is /using the cost-minimizing combination of capital and labor. /should use more of both inputs in equal proportions. /should use less of both inputs in equal proportions. /could...
#3 3. The isoquant map for a firm that produces output with labor and capital is shown on the next page. The price of labor is $20 per unit and the price of capital is $60 per unit. a) Draw the isocost lines for expenditures of TC =$300 and TC -$360. b) How many units of labor and how many units of capital should the firm hire to minimize the cost of producing Q. units of output? EXPLAIN. c) What...
Suppose a firm produces an output level according to the simple production function: Q = 5 L K, which implies M P L = 5 K and M P K = 5 L. Further suppose a firm must pay labor (L) a wage rate (w) of $5 per unit, and the rental rate (r) on capital (K) is $25 per unit. A. Find the marginal rate of technical substitution. B. Write the equation for the isocost line. What is the...
Suppose that capital costs $50 per unit and labour costs $20 per unit. If the marginal product of capital is 100 and the marginal product of labour is 30, a cost-minimizing firm should employ more of both capital and labour. employ less of both capital and labour. employ more capital and less labour. employ less capital and more labour. not change its current factor use.
Assume labor and machines are used in the production of an output. The marginal product of the last worker hired was 175 units a day and the marginal product of the last machine employed was 850 units a day. The wage to hire a worker for a day is $100 while the cost to employ the machine for a day was $400. Assuming perfect competition what would you recommend the firm do to become more efficient?
A firm uses 100 hours of labor and 20 units of capital to produce 5,000 bicycles a day. Labor’s marginal product is 4 bicycles per day and the marginal product of capital is 10 bicycles per day. Each unit of labor costs $20 and each unit of capital costs $40 per hour. If the firm wants to continue producing 5,000 bicycles per day at the lowest possible cost, it should A. Continue using 100 hours of labor and 20 units...
Assume that a firm has a fixed-proportions production function, in which one unit of output is produced using one worker and two units of capital. If the firm has an extra worker, say two workers, and no more capital, it still can produce only one unit of output. Similarly, an extra unit of capital does the firm no good.a) Draw the isoquants for this production function.b) Draw the total product, average product, and marginal product of labor curves (you will...
Question Completion Status: O all costs. QUESTION 3 Your firm must produce a specified output level. The firm uses capital and labor as inputs. If the price of capital is $40, the price of labor is $100, the marginal product of capital is 20, and the marginal product of labor is 40, then: the firm is maximizing profit but not minimizing total cost. O the firm should use less labor and more capital to minimize total cost. 0 the firm...
In the short run, a perfectly competitive firm produces output using capital services (a fixed input) and labour services (a variable input). At its profit-maximizing level of output, the marginal product of labour is equal to the average product of labour. a. What is the relationship between this firm's average variable cost and its marginal cost? O Average variable cost is higher than marginal cost O Average variable cost equals marginal cost O Average variable cost is less than marginal...
True False-Ambiguous and Explain Why 3. If total fixed costs are $500 per day, labor is the only variable cost and wages are $100 per worker per day, then the firm with the production data below will shut-down if the price is below $3 per unit. L 0 3 5 6 8 12 Q 0 100 200 300 400 500
