- “The firm’s entire marginal cost curve is its short-run supply curve.” Is the preceding statement true or false? Why?A company in a perfectly competitive market produces an output level Q = 100 where marginal revenue is equal to marginal cost and has the following revenue and cost levels: Marginal cost curve intersects the average variable cost curve at $150. Marginal cost curve intersects the average total cost curve at $200. Marginal cost curve intersects the marginal revenue curve at $170. At Q = 100, ATC = $210 and AVC = $155 Is this firm making a profit or a loss at Q = 100? What would you suggest this firm should do in the short run? Explain.A profit-maximizing firm in a competitive market is currently producing 100 units of output. It has average revenue of $10, average total cost of $8, and fixed cost of $200. What is its profit? What is its marginal cost? What is its average variable cost?
- Firms in the market for dog food are selling in a purely competitive market. A firm producing dog food has an output of 10,000 pounds of dog food, for which it sells for $0.50 a pound. At the output level of 10,000 pounds the average variable cost is $0.40, the average total cost is $0.70, and the marginal cost is $0.50. What do expect will happen in the long-run? Explain.What is the formula for profit maximization by firm ? Why does this result in the marginal cost curve becoming the same as the supply curve for firms in perfect competition? what is the difference between the short run and long run ? Why does this difference matter in our discussion of firm behavior?A firm in a perfectly competitive market has a short-run total cost function equal to SRTC=4+20q, where q is the number of units the firm produces. The firm faces a market price of $10. Enter the optimal number of units should this firm produce to profit maximize? Hint: this could be considered a "trick question", but it's easy once you think about the way a firm should profit maximize.
- In a perfectly competitive market, each firm has the cost function: q 2+10q+100. The price in the market is $50. a. What is the Marginal Cost for the firm? b. What is the Profit Maximizing Output? c. What is the Total Profit the firm receives? d. Should this firm continue to produce in the short run? Please explain. e. If the price is $20, should the firm continue to produce? Please explain.Firms in the market for dog food are selling in a purely competitive market. A firm producing dog food has an output of 10,000 pounds of dog food, for which it sells for $0.50 a pound. At the output level of 10,000 pounds the average variable cost is $0.40, the average total cost is $0.70, and the marginal cost is $0.50. (a) What would you expect the firm to do in the short run? Explain.A firm operates in a perfectly competitive industry with the following totoal production function: π (q) TR(q) - TC(q) = 20q - TC(q) where TC(q) = 50 + 4q + 2q2 a) find the firm's demand and supply functions b)Find the profit maximizing output. Is the firm making above normal profits? c)What is the long-run equilibrium?
- Suppose the short-run cost function of a perfectly competitive firm isC(q) = 10q-q^2+(1/3)q^3+100Solve for the firm’s short-run supply function q(p).If the price of the good is $100, what is the firm's profit in the short-run equilibrium?part 1. Leave 'r' and 'w' as constants. Solve the cost minimization problem to find L*(q) and K*(q). Then find the cost function C(q). part 2. At what price would the firm choose to shutdown and not produce? Provide calculations.
