Consider the duopoly computer industry problem with heterogeneous consumers analyzed in Section 2.2.3. Suppose that the computer brands are incompatible and that there are η A-oriented consumers and η Boriented consumers, withutility functions given by UA def =  2qA − pA buy A 2qB − pB − δ buy B, UB def =  3qA − pA − δ buy A 3qB − pB buy B. That is, the two types of consumers have different utility gains from their network size. Calculate the UPE prices and profit levels assuming that in equilibrium both brands are sold in the market and that the brands are incompatible.
