Microsoft sells two types of office software, a word processor it calls Word, and a spreadsheet it calls Excel. Both can be produced at zero marginal cost. There are two types of consumers for these products, who exist in roughly equal proportions in the population: authors, who are willing to pay $120 for Word and $40 for Excel, and economists, who are willing to pay $50 for Word and $150 for Excel.
a. Ideally, Microsoft would like to charge authors more for Word and economists more for Excel. Why would it be difficult for Microsoft to do this?
b. Suppose that Microsoft execs decide to sell Word and Excel separately. What price should Microsoft set for Word? (Hint: Is it better to sell only to authors, or to try to sell to both authors and economists?) What price should Microsoft set for Excel? What will Microsoft's profit be from a representative group of one author and one economist?
c. Suppose that Microsoft decides to bundle together Word and Excel in a package called Office, and not offer them individually. What price should Microsoft set for the package? Why? How much profit will Microsoft generate from a representative group of one author and one economist?
d. Does bundling allow Microsoft to generate higher profit than selling Word and Excel separately?
