Short Answer: (a) Two firms A and B are bidding for the right to produce a new art instillation in the lobby of the Carnegie museum. Two other firms, C and D are bidding to repave potholes in one of Pittsburgh's neighborhoods. In both markets, since the production takes place after the prices are set, the firms compete by setting price not quantity. If the firms only interact once, in which market would you expect firms to be able to price higher relative to cost? (b) If the firms are long-lived, and (may) interact in the future, in which of the two markets would you expect firms to be more likely to be able to sustain collusion to increase the price
