Unformatted text preview: 2 , demand is low and given by P = 20 & Q: a. Compute the monopoly price and pro&ts both when demand is high and when demand is low. b. Compute the average value of monopoly pro&ts (where the average is taken using the probabilities that demand is high or low). c. Consider a collusive strategy, where the two &rms agree to set the monopoly price after they observe the realization of demand. If one of the &rms cheats, a price war is triggered and both &rms make zero pro&ts afterwards.
