Would a perfectly competitive firm produce if price were less than the minimum level of average variable cost? Why?
The graph shows the cost curves for a perfectly competitive firm. If the market price of the product is $1.25 per unit, then the firm will earn how much profit per unit in the short run?
Does a competitive firm’s price equal its marginal cost in the short run?

- 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?arrow_forwardp= 130 - 2Q. The firm's cost curve is C(Q) = 20 + 6Q. What is the profit-maximizing solution? The profit-maximizing quantity is O. (Round your answer to two decimal places.) The profit-maximizing price is $. (round your answer to two decimal places.) What is the firm's economic profit? The firm earns a profit of $]. (round your answer to two decimal places.) How does your answer change if C(Q) = 100 + 6Q? The increase in fixed cost O A. causes the firm to increase both the price and quantity, and profit increases. O B. has no effect on the equilibrium price and quantity, but profit will decrease. OC. has no effect on the equilibrium quantity, but the equilibrium price increases and profit increases.

- Assume that a firm in a competitive market faces the following cost information. If the market price for this firm's product is $40, calculate the profit maximizing level of output for this firm using marginal analysis. It may help to create your own cost table and fill in columns for Marginal Cost and Average Total Cost based on the Total Cost information below. a.What is the level of profit for this firm at the profit maximizing output? b.To convince yourself that the quantity you found is indeed the profit maximizing quantity, try calculating what the profit would be at the next higher level of output. What did you find? c. What do you predict will happen in this market over the long run?arrow_forwardUse the following graph to answer the next question.

At that output level, it has the following costs and revenues: TC = $830,000 VC = $525,000 TR = $428,000 Given that the firm produces the level of output at which MR=MC, calculate the amount of profit (loss) this firm earns. is it Profit=TR-TC?arrow_forwardWhat 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?arrow_forward
