For the sake of argument, let’s assume that Ford, Honda, VW, and BMW, have, in fact formed a cartel. By themselves, they do not have the power to sustain it. A federal antitrust case against the carmakers aims at the wrong target. The proper solution is to rein in California’s government, which should not have cartel-making power in the first place.
Cartels need government support because they contain the seeds of their own destruction. Cartels raise prices by restricting supply—when something becomes scarcer its price goes up. That extra profit margin gives each cartel member an incentive to cheat by increasing supply on the sly. The more they do this, the more they undercut the high cartel price. In other words, self-interested companies acting selfishly naturally undo their own cartels.
Of course, this illustration only holds if the cartel’s participants control the entire market, or close to it. This is not the case with Ford, Honda, VW, BMW, and California. The two biggest automakers, GM and Toyota, are not part of the agreement. Neither is Mercedes-Benz. They can choose to differentiate their cars’ fuel economies from what the cartel members have agreed to. If consumers prefer these cars over the cartel members’ cars, then the cartel is lost, even with government support from California.
For these two reasons, the antitrust investigation against automakers should be dropped. And as Marlo also points out, the same arguments that apply to reining in California’s cartel-making powers at the state level also apply to federal CAFE standards.
