Both firms were suffering losses, despite their dominance in the satellite radio market. In 2008, the DOJ decided not to challenge a merger, and these two firms united to become Sirius XM. If you were an economic consultant for Sirius, what economic arguments would you have presented to the DOJ to persuade it not to challenge the merger? Explain
can you show the answers through a graph with two heterogeneous firms.
Unsure which is the correct answers
Suppose that three firms make up the entire wig manufacturing industry. One has a 50% market share, and the other two have a 25% market share each.
The Herfindahl index of this industry is a. 3,750
b. 1,000
c. 10,000
d. 5,000
e. 2,500
Mane Attraction, one of the firms with a 25% market share in the wig manufacturing industry, leaves the market. This would cause the Herfindahl index for the industry to __--
a. remain the same
b. fall
c. rise
The largest possible value of the Herfindahl index is 10,000 because:
a. an index of 10,000 corresponds to 100 firms with a 1% market share each
b. an index of 10,000 corresponds to a monopoly firm with 100% market share
c. an industry with an index higher than 10,000 is automatically regulated by the Justice

- Some politicians (and others) have suggested that the largest U.S. tech firms have monopolies and need to be broken up. Comment on what such breakup(s) would do to the industry that these firms are competing in. For example, the intensity of rivalry would increase, but what else would happen to the industry? How could breaking up their industry be good for industry incumbents, i.e., those companies in the industry that’s being broken up?arrow_forwardAs CEO of J&J, a huge pharmaceutical company, you and your management team face the decision of whether to undertake a $150 million R&D effort to create a new mega-medicine. Your research scientists estimate that there is a 35 percent chance of successfully creating the drug. Success means securing a worldwide patent worth $500 million (implying a net profit of $350 million). However, firm BigMed (your main rival) has just announced that it is spending $100 million to pursue the development of the same medicine (by a scientific method completely independent of yours). You judge that BigMed’s chance of success is 40 percent. Furthermore, if both firms are successful, they will split equally the available worldwide profits ($250 million each) based on separate patents. Assume that firms J&J and BigMed are risk neutral. Use decision trees and the expected profits criterion to justify your answer for the following problems.
