The market for an industrial chemical has a single dominant firm and a competitive fringe comprised of many firms that behave as price takers. The dominant firm has recently begun behaving as a price leader, setting price while the competitive fringe follows. The market demand curve and competitive fringe supply curve are given below. Marginal cost for the dominant firm is $0.75 per gallon. QM = 140,000 - 32,000P
QF = 60,000 + 8,000P, where QM = market quantity demanded, and QF = the supply of the competitive fringe.

Quantities are measured in gallons per week, and price is measured as a price per gallon.

Required:
a. Determine the price and output that would prevail in the market under the conditions described above. Identify output for the dominant firm as well as the competitive fringe.
b. Assume that the market demand curve shifts rightward by 40,000 units. Show that the dominant firm is indeed a price leader. What output (leader and follower)and market price will prevail after the change in demand?

The link between volume of production and the cost of building manufacturing operations is particularly important in industries characterized byanswers: process innovations. product manufacturing. product innovation. process manufacturing.

5. profit maximization and shutting down in the short run suppose that the market for polos is a competitive market. the following graph shows the daily cost curves of a firm operating in this market. 0 2 4 6 8 10 12 14 16 18 20 50 45 40 35 30 25 20 15 10 5 0 price (dollars per polo) quantity (thousands of polos) mc atc avc for each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. assume that if the firm is indifferent between producing and shutting down, it will produce. (hint: you can select the purple points [diamond symbols] on the previous graph to see precise information on average variable cost.) price quantity total revenue fixed cost variable cost profit (dollars per polo) (polos) (dollars) (dollars) (dollars) (dollars) 12.50 135,000 27.50 135,000 45.00 135,000 if the firm shuts down, it must incur its fixed costs (fc) in the short run. in this case, the firm's fixed cost is $135,000 per day. in other words, if it shuts down, the firm would suffer losses of $135,000 per day until its fixed costs end (such as the expiration of a building lease). this firm's shutdown price—that is, the price below which it is optimal for the firm to shut down—is per polo.

The smelting department of kiner company has the following production and cost data for november. production: beginning work in process 3,700 units that are 100% complete as to materials and 23% complete as to conversion costs; units transferred out 10,500 units; and ending work in process 8,100 units that are 100% complete as to materials and 41% complete as to conversion costs. compute the equivalent units of production for (a) materials and (b) conversion costs for the month of november. materials conversion costs total equivalent units
