. Using the two team competitive balance model with a small market team and a large market team, show how Ps, WP, WPE, and payroll would be affected by a poliCy requir- ing the large market team to give 20% of the marginal revenue which is acquired from winning more than half of their games to the small market team. (This policy will aect marginal revenue of both teams ) . Using the Cease theorem (Rottenberg invariance principle) explain why do many economists believe that free agency has not affected competitive balance? . Explain what externalities are. Give at least two examples of positive and negative externalities to a new downtown stadium for the Columbus Crew. . Find the most up to date proposal for the new crew stadium. Where is the money coming from and what is it being used for? Is it relevant that no public money will go directly to stadium building costs? Why or why not? . If the marginal propensity to consume in a municipality is 0.9, what is the value of the Simple multiplier? If a new stadium that adds $30 million in new consumption expendi- tures is built, what is the impact on the economy based on this multiplier? Suppose the Marginal Propensity to Import is 0.2, what happens to the multiplier and to the impact on the economy? . Suppose the International Olympic Committee announced that it would hold all of its Summer Games in Athens and all of its Winters Games in Sapporo. What is the likely impact on the monopoly power of the IOC, the 1003 ability to exploit an all-or-nothing demand curve, and the winners curse
