Consider the town of Cougarville that is served by 5 different fast food restaurants (but still no Taco Bell for some reason). 2 separate parent companies own all these restaurants, where "BTC Inc." owns two restaurants and "Ferdie's" owns the other three. Suppose that BTC Inc. and Ferdie's were to merge. As a regulator, what are your concerns? Aside from implementing price controls, what could you do to correct any issues created by this merger?
