- Consider the market for ice cream. Suppose that this market is perfectly competitive. The cost structure of the typical ice cream producer is as follows. Average total cost is equal to 50 1 1 ATC(Q) +÷Q, average variable cost is equal to AVC(Q) =;Q, and marginal cost is equal to 2 MC(Q) = Q. Now, suppose that a new scientific study comes out that shows that soil pollution from rock salt (a key input for making ice cream) is extremely hazardous to human health. In response, the government decides to impose harsh re-zoning restrictions on any land once used for making ice cream. This reduces the market rent for land used to make ice cream, which in turn lowers the opportunity cost of operating an ice cream factory. This reduction in the opportunity cost of capital causes the total fixed cost of ice cream production to fall to 32, but there is no change to variable cost. Give formulas for the typical ice cream producer's new average total cost curve ATC(Q) and marginal cost curve MC(Q).The graph below shows a particular firms marginal revenue (mr) marginal cost (mc) and average total cost (atc) curves, where the market is competitive. Suppose that a new management team is brought in and that this team is initially less concerned about maximizing profits than it is simply about making a profit. What range of production quantities will allow the firm to operate while earning a profit? Give you're answer by dragging the qmin to Qmax lines into their correct positions. The output will need to lie somewhere between those limits.Which of the following are true about the profit-maximizing rule of MR = MC? (check all that apply) A) The rule applies only if producing is preferable to shutting down. (B) In some cases, MR will equal MC at a fractional level of output and therefore the last complete unit of output should be produced where MR < MC. (C) The rule can be restated as P = MC when applied to a purely competitive firm because product price and MR are equal. (D) The rule is an accurate guide to profit maximization for all firms regardless of their market structure.
- Assume a competitive firm faces a market price of $100, a cost curve of: C = 0.25q + 50q + 1,600 and a marginal cost curve of: MC = 0.50g + 50. The firm's profit maximizing output level is 100.00 units, the profit per unit is $9.00, and total profit is: $900.00. However, if the firm wanted to maximize the profit per unit, how much would it produce? It would produce units. (round your answer to two decimal places) If the firm produced this output level, what would be the profit? Its profit would be S. (round your answer to the nearest penny)The table below shows the weekly marginal cost (MC) and average total cost (ATC) for Buddies, a purely competitive firm that produces novelty ear buds. Assume the market for novelty ear buds is a competitive market and that the price of ear buds is $6.00 per pair. Buddies Production Costs MC ($) Quantity of Ear Buds 5 10 15 20 25 30 35 40 2.00 2.45 3.55 4.00 5.50 5.98 8.52 pairs ATC ($) 2.00 2.00 2.15 2.50 2.80 3.25 3.64 4.25 Check my work Instructions: In part a, enter your answer as the closest given whole number. In parts b-d, round your answers to two decimal places. a. If Buddies wants to maximize profits, how many pairs of ear buds should it produce each week? b. At the profit-maximizing quantity, what is the total cost of producing ear buds? c. If the market price for ear buds is $6 per pair, and Buddies produces the profit-maximizing quantity of ear buds, what will Buddies profit or loss be per week? d. Now assume the market price is $5.50 per pair, and Buddies produces the…Suppose that each firm in a competitive industry has the following costs: Total cost: TC = 50 + 0.5Q^2The market demand curve for this product is: Qd= 120 −PThere are 9 firms in the market.a) What are each firm’s: fixed cost, variable cost, marginal cost, and average total cost? Graph the average-total-cost curve and the marginal-cost curve.b) Give the equation for each firm’s supply curve.the average-total-cost curve at its minimum? What is marginal cost and average totalc) Give the equation for the market supply curve for the short run in which the numbercost at that quantity?
- Regardless of the limitless demand, the perfectly competitive firm ( will, will not) take its own cost curves into account. Therefore, it will only sell up to the quantity where (a. P=TVC, b. P=MC, c. P=ATC) because to go beyond that point would cause the firms profits to (decrease, increase)Pierce Manufacturing determines that the daily revenue, in dollars, from the sale of x lawn chairs is R(x)=0.005x³ +0.02x² +0.5x Currently, Pierce sells 90 lawn chairs daily a) What is the current daily revenue? b) How much would revenue increase if 95 lawn chairs were sold each day? c) What is the marginal revenue when 90 lawn chairs are sold daily? d) Use the answer from part (c) to estimate R(91), R(92), and R(93) a) The current revenue is $ b) The revenue would increase by $ (Round to the nearest cent.) c) The marginal revenue is $ when 90 lawn chairs are sold daily. d) R(91) $ R(92) $ R(93) $Consider a competitive firm with total costs given by T C(q) = 100 + 10q + q^2. The firm faces a market price p = 50. (a) Graph the AT C, AV C, MC, and MR curves in a single graph, and indicate the profit maximizing level of output. If there are profits, shade the region corresponding to profit and label it. (b) If fixed costs increase from 100 to 500, what happens to the profit maximizing level of output, T R, T C, and π? (c) If fixed costs increase from 100 to 500, should the firm continue to operate in the short-run? What about the long-run?
- Assume a number of street vendors sell hamburgers in a city. Each vendor has a marginal cost of 30 NOK per hamburger sold and there are no fixed costs. The maximum number of hamburgers that any vendor can sell is 100 per day. a) If the market is perfectly competitive and the price of each hamburger is 40 NOK. How many hamburgers does each street vendor want to sell and what is each vendor’s profit per day assuming the desired quantity is sold?b) Why is this solution not a long run equilibrium?c) Suppose all the vendors merges and thus appears as a monopolist in the market. After merging marginal cost is constant. Make a diagram and explain the optimal solution for the monopolist.d) How can you explain that the solution from c) is such that the profit is maximized?e) Explain the social costs of the monopoly situation in this market. f) Suppose many consumers in this hamburger market became “addicted”. How would you explain this change in consumers demand and how would it affect social…Let's consider a company that produces a good Z, in a perfectly competitive market. The expression for the total cost of this undertaking is as follows: C( q) = 72 + 2q2 Graph the marginal cost, average cost, and average variable cost curves of this company. Your chart should be accurate. Also include the break - even point (SR) and closing point (SF).Yann's bakery operates in a perfectly competitive market where the prevailing price for a baguette (his only product) is $3.
