Read the passage below, then answer Q1–Q6
Consider the market for a single network good as discussed in the lecture, and write a different consumer’s utility function for joining the network as U(θ)=θ(a+νn^e) capturing the idea that it may be more plausible that a user who has a higher value for the standalone component of a technology also assigns more importance to the size of its network (i.e., consumers differ in their valuation of both the standalone and the network benefits). Here, a is the standalone benefit, ν > 0 measures the network effect, n^e is the expected number of users joining the network and θ is uniformly distributed on the unit interval.
Based on the above data, answer the given subquestions.
