CLO #7 – Identify examples of networks and network externalities, and determine the number of connections possible in a star network with n users.
Bank 1 and Bank 2 are considering entering a compatibility agreement that would permit the users of each bank’s automated teller machines (ATMs) access to the other bank’s ATMs. Bank 1 has a network of branches and ATMs extending from the U.S. to Mexico. Bank 1’s 12 million customers currently have access only to the 10,000 ATMs solely owned by the company on the U.S. While Bank 2’s core account holders are located in Mexico and southwestern portion of the United States, the company is expanding across the United States. Bank 2 has 15 million customers who can use any of its 14,000 ATMs.
