The supply of a Profit maximizing firms in competitive markets is zero when the price
is below the break-even price. Above this price, they supply a quantity for which the
marginal cost of production is equal to the price.
True
False
All markets that are not perfectly competitive have which of the following characteristics?
Each firm's marginal revenue is always equal to the market price.
The product that each firm sells has no close substitutes.
Firms in the market have some control over price, that is, each firm faces a downward sloping demand curve.
Firms will produce a level of output where marginal cost equals the minimum level of average cost.
A product wheat is produced under perfect competitive market structure. The market demand and supply are given by equations below
QD = 170, 000, 000 – 10, 000, 000 P
QS = 70, 000, 000 + 15, 000, 000 P
Find the equilibrium price and quantity.
Suppose one firm leaves the market with the supply equation
QS = 1000 + 1000P.
Then find new equilibrium price and quantity and interpret your results?

- Consider a perfectly competitive market where the demand for the good is given by Q=889-16p, where Q denotes the quantity demanded at price p. On the supply side, the industry supply function is given by Q=-12+4p. Find the equilibrium price, p*, and quantity, Q*, in this market. Then enter below the value of Q*, i.e., the value of the equilibrium quantity.arrow_forwardThe demand for bicycles is given by the equation: Q = 1000 - 5P There are currently 100 identical firms in this competitive market, each with the cost function: 25 C(q) =9 +20q + 50 2 %3! Calculate the short-run market equilibrium, including the market price and quantity, the number of units each firm will produce, and the profits of each firm. How much profit and producer surplus is each firm earning? a) b) If the government imposes a per unit tax of $90 per bicycle, how would this change the market equilibrium? How would the tax burden be shared by the consumers and bicycle manufacturers? c) If the government decides not to impose the tax, what is the long run equilibrium to include the market price and quantity, and the number of firms in the market? Assume the costs of the firms stay the same in the long run.arrow_forwardAllocative efficiency is an economic concept regarding efficiency at the social or societal level. It refers to producing the optimal quantity of some output, the quantity where the marginal benefit to society of one more unit just equals the marginal cost. The rule of profit maximization in a world of perfect competition was for each firm to produce the quantity of output where P = MC, where the price (P) is a measure of how much buyers value the good and the marginal cost (MC) is a measure of what marginal units cost society to produce. A monopolist... Group of answer choices Would try to achieve allocative efficiency to compete with the other firms who own a larger market share. Will prefer to operate where price < average total cost. Has no motivation to operate at an output level where P=MC, once a barrier is in place and no longer has to worry about competition. Will experience greater profits if it sets prices equal to average total cost.arrow_forward
- Which of the following is NOT a requirement for a market to be perfectly competitive?arrow_forwardIn the perfectly competitive market, if a single producer increases or decreases production while the other competitive companies remain constant, the effect on the total supply and on the market price is significant. True or falsearrow_forwardSuppose you observe that a particular business has earned positive profits over time and maintained a large share of the market. Which of the following is likely to be true? Group of answer choices Demand for the product is probably elastic The business must be engaging in price discrimination There is probably a barrier to entry preventing new firms from competing Supply must be inelastic Government intervention in this market is probably limitedarrow_forward
- The market for paperback detective novels is perfectly competitive. Market Demand is given by Q=393-7P. Market Supply is given by Q=3P-9. Suppose 55 units are bought to the market. Consider the Marginal Cost of production for these 55 units. What is the maximum Marginal Cost of production of these 55 units? Enter a number only, do not include the $ sign. Hint: 55 doesn't have to be the market quantity.arrow_forwardProfit is the incentive that drives our market economy. Firms make production, pricing, and hiring decisions based on their quest for profit. But what happens when a firm discovers that it can make dramatically higher profits by stopping production altogether? In December 2000, due to wild swings in the market for electricity, Kaiser Aluminium faced just such a decision. Kaiser Aluminium had contracted with Bonneville power for all of its electricity needs and found itself in the unique position of being an electricity consumer and, potentially, an electricity reseller. By December 2000, Kaiser faced a difficult decision of continuing its current aluminium production and profit levels, or closing the plant to dramatically increase its profit by simply reselling its electricity. When making production decisions, firms must consider both their costs and revenues. One important concern for many firms is utility costs. In 1996, Kaiser Aluminium Corporation in Spokane, Washington, entered…arrow_forwardA market is at long-run equilibrium of P* = S194 and Q* = 76800 units. All firms in the market are identical, and each has a marginal cost curve of P = 2 + 2g, where g is the quantity produced by that firm only. How many firms exist in the market? Answer:arrow_forward
- Suppose you are the manager of a firm in the textile industry. You have just learned that the government has placed the textile industry at the top of its list of industries it plans to regulate and intends to force the industry to expand output and lower the price of textile products. How should you respond?arrow_forwardFirms should choose to produce on the inelastic portion of the demand to further increase its market power. Do you agree or disagree. Explain your answer.arrow_forwardA competitive market has demand of Q = 50 - 0.5P and total cost of production is C=70q for each firm. What is the effect of an innovation by one firm that gives a marginal cost of $28? a. This is a drastic innovation that causes the market quantity to be 18. b. This is a drastic innovation that causes the market quantity to be 36. c. This is a drastic innovation that causes the market quantity d. This is a non-drastic innovation that causes the market quantity to be 18.arrow_forward
