1.Microsoft is one of the leading software companies. Prior to 2000, Microsoft’s share of the market for personal computer operating systems stood above 80 per cent. However, since the twenty-first century Microsoft’s market share has steadily declined to 40 per cent. This is due to the rise in competing software producers such as Apple macOS (10%), Google's Android OS (35%), Linux Operating System (35%), and Apple iOS (5%). The market share of each company is provided in parentheses. Google and Linux have decided that it would be in their best interest to work together to serve the market. This is not common knowledge to the person’s outside of the companies.

Would the government be likely to challenge that proposed merger? c. If Carrot Computers horizontally merges with its competitor Blueberry Handhelds, by how much would the Herfindahl index change for the touch screen industry?arrow_forwardB.A measure called Herfindahl-Hirschman Index is used to measure the degree of competition in an industry. The HHI is the square of each firm's market share summed over the firms in the industry. (Where market share is the percentage of sales in the market accounted for by that firm). For example, if an industry contains only three firms and their market shares are 60%, 25%, and 15% then the HHI (by squaring each firm's share and summing them) is 4450. Some economists classify the market structures according to HHI scores. An HHI below 1,500 indicates astrongly competitive market, between 1,500 and 2,500 indicates a somewhat competitivemarket, and over 2,500 indicates an oligopoly. Given the information in the table, calculate the HHI in this industry. If yahoo and Bing were to merge, what would the HHI be?
