3. In the case of Safeway in California, a lawsuit by the retailer's rivals has been filed accusing Safeway of "unfair business practices" for selling gasoline at prices that are "too low" and "below cost." If the plaintiffs prevail, a Bay Area judge may force Safeway to raise its gas prices, because "prices below cost" are illegal under the Unfair Practices Act.
So in some cases the government enables incumbent producers like limousine companies to engage in collusive behavior and fix high prices, and in other cases it brings charges against book publishers for collusive behavior and fixing high prices, and in other cases it might find retailers like Safeway guilty of charging low prices and force them to charge higher prices? Welcome to the wacky world of antitrust.
