He is trying to decide whether or not to market his own brand of roller blades; the product would sell for $50 per pair. His marketing department at Players conducts an exhaustive survey and estimates the following elasticities: price elasticity of demand for roller blades is -2.5 in this price range, the current price elasticity of demand for snow boards is -0.75, cross price elasticity of roller blades for roller skates is -1.7, cross price elasticity of roller blades for bicycles is 0.8, and income elasticity for roller blades is 2.8 Are the following statements true, false, or uncertain? Carefully explain your reasoning. A. Roller blades and roller skates are substitutes, but roller blades and bicycles are complements. B. If Players increases the price of roller blades, it would be able to lower the price of snowboards by 4 percent and hold firm revenues fixed. C. If the average consumer income increases by 2.7 percent, the quantity of roller blades sold will increase by 7.56 percent. D. Players could offset a 2 percent decrease in consumer income with a 2.24 percent decrease in the price of roller blades and hold sales fixed. E. Players could increase its expected revenues if it would increase the price of its roller blades. 9. A pizza chain recently offered the following special promotion "buy one pizza at full price and get your next three pizza for just $5 each!" Assume that the full price of a pizza is $10, your daily income is $40, and price of all other goods is $1 per unit. a. Draw a budget constraint for pizza and all other goods that reflect your situations both before and during the special promotion. (Put the quantity of pizzas on the horizontal axis.) Indicate the horizontal and vertical intercepts and the slope of the budget constraint. b. How is this special offer likely to alter your buying behavior? c. Illustrate at least two different scenarios for a customer based on the shape of their indifference curve, and explain what the different shapes of the indifference curve suggest about the customer's preference for pizza and all other goods. 10. Evaluate and show graphically your responses for the following statements when the Price of X increases, then a. If X is Giffen, then it must be inferior, but if a good is inferior it doesn't have to be Giffen. b. If X is inferior, the demand for X cannot be elastic.
