Verizon can be viewed as a first mover. Now suppose both ATT and Verizon are considering whether and how to enter a potential market. Market demand is given by the inverse demand function p= 900−q1−q2, where p is the market price margin, q1 is the quantity sold by Verizon and q2 is the quantity sold by ATT. To enter the market, a retailer must build a store. Two types of stores can be built: Small and Large. The Small store requires an investment of $50,000, and it allows the retailer to sell as many as 100 units of the goods at zero marginal cost. Alternatively, they can pay $175,000 to construct a Large store that will allow it to sell any number of units at zero marginal cost. Assume Verizon enters and builds a Large store (i.e. chooses to build a Large store L1 at the first stage.) Calculate Verizon's profit for the following cases: a.) ATT chooses not to enter N at the second stage after viewing Verizon's choice. b.) ATT chooses to build a Small store S at the second stage after viewing Verizon's choice. c.) ATT chooses to build a Large store L at the second stage after viewing Verizon's choice.
