A firm combines two resources, A and B, to produce an output level Q in a purely competitive market. The cost of a unit of A is $5 and the cost of a unit of B is $12. The marginal revenue product of A is $5 and the marginal revenue product of B is currently $12. What would you recommend that the firm do given this resource combination?
The marginal revenue product of A is $5
The cost of a unit of A is $5
Ratio of MRP of A and cost of A = $5/$5 = 1
The marginal revenue product of B = $12
The cost of unit of B is $12
Ratio of MRP of B and cost of B = $12/$12 = 1
It can be seen that ratio of marginal revenue product and cost for both inputs, A and B, is same.
Thus,
The firm should keep the resource combination unchanged.

A monopolistically competitive firm that wishes to maximize profits will choose to produce that level of output where: Price of the good is equal to the marginal revenue of producing the last unit of the good Price of the good is equal to the marginal cost of producing the last unit of the good. Marginal revenue is equal to marginal cost. ATC is at the lowest point possible. An industry has eight firms with the following market shares: 5%, 20%,...

A firm has the following total costs, where Q is output and TC is total cost: Q TC 0 $ 100 1 110 2 130 3 160 4 200 5 250 6 310 7 380 8 460 9 550 10 650 11 760 Say the firm is in a perfectly competitive market. If the current market (equilibrium) price is $ 70, at what output level will the firm as a profit maximizer produce at? Say the market price rises to...
If the firm produced at this output level, what would the profit be? (Round to two decimal points) Assume a competitive firm faces a market price of $100, a cost curve of C 0.64q 25q+1,600 and a marginal cost curve of MC 1.28q 25. The firm's profit maximizing output level is 58.59 units, the profit per unit is $10.19, and total profit is: $597.03 However, if the firm wanted to maximize the profit per unit, how much would it produce?...

What equation do you use to find a cost-minimizing combination of inputs for a certain output level Q.? K C. The marginal products of labor and capital are given by MP, = 50, and L MPK = 50, L respectively. The price of labor is $5 per unit, and the price of K capital is $20 per unit. What is...
produce 16000 units of output. What is the cost minimizing combination of capital and labor for this firm? What is it's minimized cost of producing 16000 units of output? 2.2 Problem 2 In a perfectly competitive market all firms (including potential entrants) have a total cost function given by TC(Q) = 100Q - QP + ', where Q is that firm's output. Therefore, each firm's average cost function is AC(Q) = 100-Q+ Qand each firm's marginal cost function is given...

What level of output will the firm produce? b. What is the firm's producer surplus? c. Suppose that the average variable cost of the firm is given by AVC(q) = 3 + q. Suppose that the firm's fixed costs are known to be $3. Will the firm...
