Researchers estimated the demand function for beer. The estimated equation is: In Beer = 7.28-0.980ln Pr +0.065ln PrCider - 0.040ln PrWine +0.074Income + e where In Beer is the natural log of beer consumed (in millilitres), In Pr denotes the natural log of the price of beer, In PrCider is the natural log of cider price, InPrWine is the natural log of wine price, and Income denotes income in thousands £s. (a) What is the change in beer demand when the price of beer increases by 1 percent? (b) What is the change in beer demand when the price of cider falls by 20 percent? (c) What is the change in beer demand when the income increases by 2.5 percent, when the income equals £40,000?

A stadium can seat 60,000 people. Assume 35% of seats are not occupied (not for sale) because of Covid-19 and social distancing requirements. You are told that the current price of tickets is $70 and that the demand is linear and that the demand function (Qd) = 60,000 - 250P. examine the market for tickets for games at the stadium during these Covid times. You should Illustrate themarket for tickets using a demand and supply diagram. Show all your calculations and properly label the diagram. At $70 a ticket the cap on the number of seats available (because of Covid restrictions) is creating a shortage. How many people miss out on tickets when they are priced at $70 per ticket?

The R J smith corporation is a publisher of romance novel. The corporation hires an economical to determine the demand for its product. After months of hard work the analyst informed that the demand for the firm's novel is given by the following equation: Q=12000-5000 Px+5I+500 Pc Where, P, is the price charged for the R J Smith novel. I is the income per capita. PC, is the price of books from competing publisher. Assume, that the initial values of Px, I and Pc are. $5, $10000 and $6 respectively. Using the information, the manager wanted to (i) determine what effect a price increased would have on total revenue. (ii) Evaluate how sale of the novels would change during a period of rising incomes. (iii) Assess the probable impact if competing publishers would raise their price .

You are presented with the following data from The Home Depot (THD) on sales of its Snowminator Snow Shovel during the winters of 2012-2015, throughout Canada. The product’s price (P), measured in Canadian Dollars, is: 26, 22, 18, 14, 10, 6, and 2. The corresponding quantity demanded (Qd) in the Northern part of the nation, measured in millions of shovels, was: 3, 6, 9, 12, 15, 18, and 21. While the corresponding quantity demanded, measured in millions of shovels, in the Southern part of the nation was: 4, 6, 8, 10, 12, 14, and 16. Assume all the data was retrieved internally from The Home Depot. In two separate graphs that you have created using Excel, clearly and accurately graph the demand and total revenue curves for the Northern part of Canada. These will be graph # 1 and # 2, respectively. In a separate graph from part A above, clearly and accurately graph the demand curve for the Southern part of Canada. This will be graph # 3.
