Questions
1. In 2005, a major U.S. automaker announced a new discount plan for its cars for the month of June. It offered consumers the same price that its employees paid for new cars. When the automaker announced in early July that it was extending the plan for another month, the other 2 major U.S. automakers announced similar plans. What market structure is exhibited in this story and what specific characteristics of that market structure does it demonstrate?

3. The Telecommunications Act of 1996 included provisions to deregulate the cable industry. In 2003, consumers complained that cable rates had increased by 45% since the law was passed. Only 5% of American homes had a choice of more than 1 cable provider in 2003. Those homes paid about 17% less than those with no choice of cable provider. How effective had deregulation been in the cable industry by 2003? Explain your reasoning.
