3. Consider the perfectly competitive markets for bottled water in two cities, A and B. Both have a downward-sloping demand curve and upward-sloping supply curve, and each market is currently in long run equilibrium at the same price. The demand curves are similar, but in city A the supply curve is more price elastic than in city B. a) There's a shock: an accident causes the tap water in the area to become undrinkable. In two diagrams, one for each city, compare the effect on price and quantity traded in the two cities, assuming that a new equilibrium is reached. Explain your diagrams. b) Following on from your answer to a), explain what would happen in the model to the number of suppliers and their profitability, in each of the short run and the long run.
