Numerical Problems

Managerial Economics Numerical Problems DEMAND AND ELASTICITY OF DEMAND Problem 1 The following be implore and supply equations of a pen manufacturer. Qd = 5,00,000 50, 000 P Qs = -1,00,000 + 1,00,000 P Find 1. At what average monetary value, direct of demand is equal to zero. 2. At what average price, level of supply is equal to zero. 3. Calculate the equilibrium price and quantity. Problem 2 Yashika Limited manufactures an automatic camera that currently sells at uS$90.Sales book of account is about 2,000 cameras per calendar month in a city. A dear competitor, Minolta, has buffet the price of a similar camera it makes from US$ 100 to US$80. Yashikas economist has estimated the arc cross elasticity of demand between the two rival firms products at about 0. 4, given current incomes and price levels. What impact, if any, will the carry out by Minolta have on the total revenue generated by Yahika, if it leaves its current price un stird? YASHIKA MINOLTA P1y = 90 P1m = 100 Q1y = 2,000 P2m = 80 Q2y = to be determined cosset elasticity of demand = 0. 4 Problem 3 Bajaj Appliances Ltd. manufactures a line of microwave ovens costing US$500 each.Its gross revenue have averaged about 6,000 units per month during 2001. In June 2002, Bajajs closest competitor LG had cut its ovens price from US$600 to US$450. Bajaj noticed that its sales volume declined to 4,500 units per month after the price cut by its rival LG. 1. What is the arc cross price elasticity of demand between the two? 2. Would you say that these two firms are very close competitors? 3. If Bajaj knows that the arc price elasticity of demand for its ovens is 3. 0, what price it would have charged to sell same number of units it did before its rival LG resorted to a price cut?Problem 4 Demand for mobile phone handsets by a popular company in Bangalore city is estimated to be Qd = 2,50,000- 35P. If this relationship is approximately logical for next year also, 1. How many mobile phones would be d emanded at a price of Rs. 2,000, 4,000, and 6,000 a set? 2. Compute the arc price elasticity between 2,000 and 4,000 4,000 and 6,000. 3. Calculate point elasticity at 2,000, 4,000 and 6,000. 4. If last year 25,000 units were sold, what would have been the average price? 5. What is the highest theoretical price for the mobile handset in Bangalore for this seller?Problem 5 The demand function for wall clocks in a city has been estimated to be Q= 2000 +15Y-5. 5P Where Y is income in thousand rupees, Q is quantity in units, and P is unit price. When P=150, y =15, find 1. Price elasticity of demand 2. Income elasticity of demand Problem 6 Two goods have a cross elasticity of +1. 2 1. Would describe them as substitutes or compliments? Give examples for supporting the category that you chose. 2. If price of one of the two rises by 5%, ceteris paribus, what happens to the Qd of the other? Problem 7The demand for lunches in an institute canteen was estimated to be Q= 16,415. 21-262. 743P, wh ere Q= lunches served, P= price in rupees. 1. Compute the price elasticity of demand at a price of Rs. 40, Rs. 50 per lunch 2. What is the arc price elasticity of demand between the prices 40 and 50? Problem 8 Pepsodent sells a toothbrush for Rs. 25. Its sales have averaged 8,000 units per month over the last year. Recently, its close competitor, Colgate, reduced the price of its product from Rs. 35 to Rs. 30 per toothbrush. As a result, Pepsodents sales declined by 1,500 units per month. . What is their cross elasticity? What relationship it indicates? 2. If Pepsodent knows that it has a cross elasticity of 1. 5 with Colgate, how much it should now charge to restore previous sales after the price cut by Colgate? (Assume Colgate retains its price at Rs. 30 itself and does not retaliate). 3. What is the total monthly revenue of Pepsodent before and after the price change in (2) above? 4. Is the result in part (3) above necessarily desirable? What other factors would have to be taken into consideration?
