Consider a market with demand given by Q=100-P. The market is perfectly competitive with 60 firms and all have same cost structure. They all have no fixed costs and a constant variable cost of USD 40. How do we get the market supply curve for this situation.
c) Assume that demand for Starbucks is q, = 10 - 2p, + P, and demand for |3| Gloria Jeans is q, = 10 – 2p, + Ps. qs and Ps are quantity demanded and price for Starbucks coffee. q, and p, are quantity demanded and price for Gloria Jeans coffee. Assume costs are zero for each firm. Calculate the equilibrium prices, quantities, and profits for each firm. Show the equilibrium on a graph. What t ne of
Henry Potter owns the only well in town that produces clean drinking water. He faces the following demand, marginal revenue, and marginal cost curves: Demand: P=60−QP=60−Q Marginal Revenue: MR=60−2QMR=60−2Q Marginal Cost: MC=QMC=Q On the following graph, use the blue line (circle symbol) to graph Mr. Potter's demand curve. Then, use the black line (cross symbol) to graph his marginal revenue (MR) curve. Next, use the orange line (square symbol) to graph his marginal cost (MC) curve. Finally, use the grey point (star symbol) to indicate the profit-maximizing price and quantity. : The profit-maximizing quantity is___units, and the profit-maximizing price is___. Mayor George Bailey, concerned about water consumers, is considering a price ceiling that is 10% below the monopoly price. At this new price, the quantity demanded would be___units. At this quantity, the marginal cost would be___the price. Therefore, the profit-maximizing Mr. Potter___produce…
Consider the weekly market for gyros in a popular neighborhood close to campus. Suppose this market is operating in long-run competitive equilibrium with many gyro vendors in the neighborhood, each offering basically the same gyros. Due to the structure of the market, the vendors act as price takers and each individual vendor has no market power. The following graph displays the supply (S = MC) and demand (D) curves in the weekly market for gyros. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from competition. Competitive Market 4.0 S-MC 35 30 X 2.0 1.5 1.0 + 20 30 PRICE (Dollars per gyra) 5.0 0.5 RICE (Dollars per gyro) 0 5.0 4.5 4.0 3.5 3.0 2.5 Now assume that one of the gyro vendors successfully petitions the neighborhood development board to obtain exclusive rights to sell gyros in the neighborhood. This firm buys up all the rest of the gyro food trucks in the area and begins to operate as a monopoly. Assume that this…
The following graph illustrates the demand and marginal revenue curve (D=MR) of a perfectly competitive firm. Suppose that when the firm produces 70 units, its average variable cost equals $30 per unit and its average total cost equals $55 per unit. Use the green rectangle (triangle symbols) to plot the total cost of producing 70 units. Next, use the grey rectangle (star symbols) to plot the total variable cost of producing 70 units. Then, use the tan rectangle (dash symbols) to plot the total revenue at 70 units. Finally, use the purple rectangle (diamond symbols) to plot the profit or loss at 70 units. PRICE AND COST (Dollars) 100 90 80 70 60 50 40 30 20 10 0 O 10 20 30 40 50 60 QUANTITY (Units) +ATC + AVC 70 D=MR 80 90 100 Total Cost Total Variable Cost Total Revenue Profit or Loss ?
Consider the market for tilapia. Ripple Rock Fish Farms, a small family fishery in Ohio, and The Fishin’ Company, a large corporate supplier, are both producers of tilapia. The marginal cost curves for both firms are shown in the accompanying graph. a. Suppose the market price of tilapia is $2.50 per pound. Move point A to Ripple Rock’s quantity sold.

Consider the perfectly competitive market for titanium. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost ( MCMC ), average total cost ( ATCATC ), and average variable cost ( AVCAVC ) curves shown on the following graph
Suppose that you have a management job at a firm like Estrella River Ranch, a beautiful vineyard and one of more than 200 vineyards growing cabernet sauvignon grapes in California. Assume that the market is perfectly competitive. Also, assume that you cannot instantly change production when demand changes, and grapes cannot be stored, so your firm must sell all of the grapes it grows. The adjacent figure (Figure A) shows the situation at your California vineyard. If demand is high, the price is $3,000 per ton of grapes, and if the price is low, the price is $1,000 per ton of grapes. Producing 300 tons of grapes maximizes your firm's expected profit. Suppose that there is no fixed cost. If demand is high and your firm produces 300 tons of grapes, its economic profit on the tons of grapes between 100 and 300 tons is $ If demand is low and your firm produces 300 tons of grapes, its economic loss on the tons of grapes between 100 and 300 tons is dollars. (Enter a negtive sign to indicate a…
Initially, all firms in a perfectly competitive market are in long-run equilibrium. Assume that the market demand for the product produced by the firms in the market suddenly rises. Suppose the following graph shows the marginal revenue (MR) and marginal cost (MC) curves of a firm in this market at its initial long-run equilibrium, with an equilibrium price of P₁ and a profit-maximizing quantity of output of Q₁. Show the short-run effect of the increase in market demand on this firm by shifting the marginal revenue curve, the marginal cost curve, or both on the following graph. PRICE AND COST 2 MC Q₂ QUANTITY In the short run, the firm will respond by producing In the long run, some firms will respond by PRICE MR QUANTITY Supply MR Demand O Shift the demand curve, the supply curve, or both on the following graph to illustrate both the short-run effects and the new long-run equilibrium after firms finish adjusting to the increase in market demand.

Assume that apples are produced in a perfectly competitive market. Columbia’s Orchard is a typical firm that grows and sells apples. Currently, Columbia earns zero economic profit, and the market price of apples is $10 per basket. Draw a correctly labeled graph showing Columbia’s demand curve, average total cost curve, and marginal cost curve, and show the profit-maximizing quantity, labeled Qc. Answer: Suppose an increase in the popularity of apple, the demand for apple increases. How will the increase in the demand for apples affect Columbia’s economic profit in the short run? Explain. Answer: What will happen to Columbia’s economic profit in the long run? Explain.
