The annual demand for coffee by U.S.consumers is given by the demand curve Q = 250 – 10P, where Q is quantity (in millions ofpounds) and P is the market price per pound of coffee. World producers can harvest and shipcoffee to U.S. distributors at a constant marginal (= average) cost of $8 per pound. U.S.distributors can in turn distribute coffee for a constant $2 per pound. The U.S. coffee market iscompetitive. Congress is considering a tariff on coffee imports of $2 per pound.i. If there…a) A Dutch Brewing company produces Heineken beer, assume further that the marginal cost of producing a six pack of Heineken Beer is $6. Dutch Brewing company sells Heineken in two different Markets namely Africa and Europe whose inverse demand functions are ?? = 24 − ??and ?? = 12 − 0.5?? respectively.Requireda) Calculate the profit maximising Price-Quantity combinations in these two markets Africa and Europe.b) With this Pricing strategy calculate the profit. c) If competitive output (P=MC=6) for Africa is 18 and Europe is 12, Compute the deadweight losses in the two markets. d) Clearly illustrates that the third degree price discrimination is welfare improving over a single price policy. e) Suppose these markets were no longer separated. How would you construct the market demand in this situation? Would the monopolist’s profit-maximizing single price still be 15?
- Assume a perfectly competitive market. Draw the average total cost, average variable cost,marginal cost, and marginal revenue curves for a good. Determine the profit-maximizing levelof output given that the price of the good is above the minimum average variable cost butbelow the minimum average total cost. Is the profit at the chosen price point positive,zero, 0r negative? Shade the area representing profit. Assume a monopoly market. Draw the average total cost, marginal cost, marginal revenue,and demand curves for a good. At what price will the monopolist sell? What is theprofit-maximizing level of output at this price? Shade the area representing profit.ASAP 26) Without restrictions, the market supply curve is horizontal at P = 5, and the inverse demand curve for taxi cab rides is P = 20- Q in a competitive market. Subsequently, only 10 taxi cabs are allowed in the market. Find the value of deadweight loss. Make sure to show your answer both graphically and algebraically.4. Suppose the market demand and supply functions are QD = 58,200 – 310P and QS = 90P - 1400. You have just graduated and moved to this city; as a new MBA and an entrepreneur, you are considering entering the market for this product. a. Determine the equilibrium price and quantity in this market. b. You’ve researched and found that most firms in the market currently experience costs such that TC = 220 + 210Q – 4.1Q2 + 0.06Q3. Determine whether or not you should enter this market. Use graphs to support your answer. (Remember that you can Format Axis and change the Minimum and Maximum Bounds of your axes to “zoom in” to a graph in Excel.) c. Due to unforeseen delays, you don’t enter the market. However, a year later the market supply has changed to QS = 90P + 3400. Are you surprised at this shift in supply? d. Given the new supply conditions, determine whether or not you should enter the market.
