ABSTRACT:Demands have been growing upon firms to take actions in the interests of workers, the environment, local communities, and others. Firms sometimes have felt they could best discharge such responsibilities by cooperating with other firms. This, however, is suspect from the point of view of a purely economic interpretation of competition law, since interfirm agreements may raise prices and thus lower welfare for consumers. Should competition law remain focused on competition enhancing economic welfare, or be reformed to allow for acts (...) of cooperation that are socially beneficial? To answer this question, the article provides a philosophical reevaluation of the deep-seated view that firms are merely private actors. It argues that demands of political legitimacy should also be addressed at firms cooperating together, and that standard views of democratic accountability should be broadened, introducing a model of delegated, sequential decision making which allows regulatory agencies and parliaments to control interfirm agreements.
