There are two groups of firms below.
Group 1: firms in the retail sector (e.g. Amazon; Wal-Mart; Target; Kohl's; Sears; Macy's)
Group 2: firms in the wireless services industry (e.g. Verizon; AT & T; Sprint/T-Mobile) (this about telecommunication services, not about the sale of phones)
For each group determine and explain if the group is monopolistic competitive or an oligopoly. You need to specific for both in which market structure the firms operate)
Then choose one of the firms from one group. Using a Porter's analysis what are the threat to profitability?
What will firms often do if they find a strong complementary
relationship between two products?
a. They will usually concentrate on the larger market and largely ignore
the smaller market
b. They will usually avoid getting involved in the complement market
for fear of an antitrust case
c. They will usually get rid of their interests in the complement market
in order to avoid a conflict of interest
d. They will try to form a cartel with complement producers to raise
the price of the complement
e. They will often produce the product in order to reduce its price
What sign will the cross elasticity for a complement have?
a. Positive
b. Negative
C. Zero
d. Sign does matter
.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 a 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 a strongly competitive market, between 1,500 and 2,500 indicates a somewhat competitive market, 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?
