- Based on market research, a film production company in Ectenian obtains the following information about the demand and production costs of its new DVD:Demand: P = 1,000 – 10QTotal Revenue: TR = 1,000Q – 10Q2Marginal Revenue: MR = 1,000 – 20QMarginal Cost: MC = 100 + 10Qwhere Q indicates the number of copies sold and P is the price in Ectenian dollars.d. Suppose, in addition to the costs above, the director of the film has to be paid. The company is considering four options:i. A flat fee of 2,000 Ectenian dollarsii. 50 percent of the profitsiii. 150 Ectenian dollars per unit soldiv. 50 percent of the revenueFor each option, calculate the profit-maximizing price and quantity. Which, if any, of these compensation schemes would alter the deadweight loss from monopoly? ExplainA firm has a linear demand function for its product. When the price of the product isSh.220, the quantity demanded is 40 units. When the price increases to Sh.240, thequantity demanded becomes 30 units. In addition, the firm’s marginal cost function isgiven by:MC = 40q – 2q2 + 2Fixed cost = Sh.5 millionWhere q = quantity demanded, MC = marginal cost (Sh. million)Evaluate the level of output that maximizes profits.Suppose a firm engaged in the illegal copying of DVD’s has a daily short run total cost function given by: STC = (q^2)+25 If pirated DVD’s sell for $20, how many will the firm copy each day? What will its profits be? What is the firm’s short run producer surplus at P=20? Develop a general expression for this firm’s producer surplus as a function of the price of pirated DVD’s.
- Suppose the inverse demand curve in a market is D(p) =a-bp, where D(p) is the quantity demanded and p is the market price. Firm 1 is the leader and has a cost function c1(y1)=cy1 while firm 2 is the follower with a cost function c2(y2 )= y^22/2 (image of function attached). Firm 1 sets its price to maximise its profit. Firm 1 correctly forecasts that the follower takes the price leader’s chosen price as given (price taker) and chooses output so as to maximise its own profit. Write down the profit function of the follower. Calculate the profit maximising quantity that the follower selects given the leader’s chosen price p (i.e., calculate the follower’s supply curve S(p)). Interpret the solution to the profit maximising problem. B. The leader is facing the residual demand curve R(p)=D(p)-S(p) with D(p) and S(p) as defined in (c) above. Calculate the leader’s residual demand curve using the result in (b). Solve for p as a function of the leader’s output y1, i.e. the inverse demand…A competitive firm’s production function is given by y= f(x1,x2)= 4x11/2 + 10x21/2 a) The price of factor 1 is 1, the price of factor 2 is 1, and the price of output is 2. Find the profit-maximizing quantities of x1 and x2? What is the profit-maximizing quantity of output? b) Redo part (a), this time by first deriving the firm’s factor demand functions and the supply function, and then substituting the prices in these functions.Best Orange Juice Company is located in Oman. The cost function for total orange juice production (x) is given by C(q) = 0.25x2. Their orange juice is demanded only in Muscat (Muscat demand is xm= 100-2Pm) and Salalah (Salalah demand is xs= 100-4Ps). Therefore, the total demand is x=xm+ xs. If the company can control the quantities supplied to each market, how many should it sell in each location to maximize total profits? What price would it charge in each location?
- The market for drones is perfectly competitive. Assume for simplicity that fractions of everything, including firms, is possible. We have identical firms, each with a Total Cost curve of TC=341+q^2 and Marginal Cost curve MC=2q. Market demand is Q=627-2P. If the market price is $84, what is the short-run profit maximizing quantity for each firm?A firm has a linear demand function for it's product.When the price for the product is Sh.220,the quantity demanded is 40 units.When the price increases to Sh.240 the quantity demanded becomes 30 units.In addition,the firm's marginal cost function is given by; MC = 40Q-2Q^2+2 Fixed cost = Sh. 5 million Where Q= quantity demanded, Mc= marginal cost(cost in Sh. Million) Required 1.The level of output that maximises profits 2.The maximum profit 3.The price of the product at a maximum profitA company manufacturing laundry sinks has fixed costs of $100 per day but has total costs of $2,500 per day when producing 15 sinks. The company has a daily demand function of q = 360 − p, where q is the number if laundry sinks demanded and p is te price of a laundry sink. (d) How many laundry sinks will the company need to produce in order to maximise it′s profits?
- Two dairy farmers produce milk for a local town with local milk demand given by Q=100-0.3333333333P(P denotes price measured in Rands, Q denotes the quantity measured in liters). Both farmers have the same cost function given by TC=150+2q(wheredenotes output). (h) What if farmer 1 is a leader and farmer 2 a follower, determine the price, quantity and profits made by these two farmers.Elsie sells homemade lemonade. If she prices a glass of lemonade at $3, she sells 12 glasses a day. If she gives a $0.50 discount (per glass), she can sell 3 more glasses per day. Write a linear demand equation q = mp + b, where p is the price per glass, and q is the number of glasses she can sell per day. Suppose that it costs her 20 cents a glass to make lemonade. There is no fixed cost. Write down the revenue function, cost function, and profit function as functions of p. How much should she charge per glass to maximize her profit? What is the maximum profit?Eccles Incorporated (based in Ogden) manufactures precision steel sprockets for applications including transportation, defense, logistics and sporting goods. The total cost curve for Eccles Incorporated sprockets is given by Total Cost = 15, 600 + 0.5Q + 0.025Q^2, where Q is the number of sprockets Eccles Incorporated manufactures in a month. The Eccles Incorporated marginal cost curve is given by Marginal Cost = 0.5 + 0.05Q. (a) Derive and graph the Eccles Incorporated firm-level supply curve for sprockets.
