Home Depot knows that some buyers are only planning to paint one or two rooms of their homes. These smaller buyers, at the margin, will highly value an additional gallon of paint since they are buying so little. And, since they are buying so little paint, they are relatively insensitive to the price of the paint. Home depot also knows that other buyers are going to paint every room in their homes and will be purchasing many gallons of paint. These larger buyers will possess relatively low marginal valuations and will be much more sensitive to paint prices than smaller buyers. Obviously Home Depot employees cannot identify small and large buyers prior to the sales transaction, so they must offer all paint buyers the same pricing schedule-one that is designed to give larger buyers lower prices. In this way, Home Depot customers self-select themselves into lower- or higher-price groups. Critically analyze the case through: a. Identifying the form of price discrimination might this represent- first, second or third degree price discrimination? (3 marks) b. Formulating two types of pricing schedule to offer lower prices for larger quantities. (7 marks)
