3. The following is taken from the San Jose Mercury News, July 27, 2000:
"The Mexican arm of U.S. Internet giant America Online Inc. said on Wednesday it started a financing program to help aid in the purchase of personal computers, joining a list of companies that have launched similar programs to promote Internet use.
"AOL will be joined in the program by computer giant Compaq Computer Corp. and Mexico's second-largest banking group Banamex Accival, AOL said in a statement.
"The program, known as 'PC Facil' (Easy PC) aims to help clients acquire a PC, enabling them to hook up to the Internet and the 'unique benefits' of AOL service, said AOL Director of Markets Erick Sydow. In Mexico there are only an estimated five personal computers per 100 people, which is one of the reasons that Internet use there is still low."
Using the concepts you learned in this class, explain:
a. Why is AOL subsidizing computer sales in Mexico?
b. What do you conclude about the cross-elasticity of demand for AOL services and computer ownership?
c. Why would Compaq and Banamex also be interested in this effort?
