Researchers and regulators have observed that this is not simply a matter of consumer apathy, but that firms often understate and obscure their actual data practices, preventing consumers from making informed choices. This paper defines, and provides examples of, a set of “concealed data practices”. These concealed data practices create objective costs and detriments for consumers, making them more susceptible to criminal activity, discrimination, exclusion, manipulation and humiliation. This paper argues that these practices are not only problematic in terms of consumer protection and privacy regulation. Concealed data practices should also be of concern to competition policy due to their role in chilling competition on privacy; preserving substantial market power by means other than superior efficiency; and deepening information asymmetries and imbalances in bargaining power. The paper concludes by outlining four ways in which these factors should be taken into account by competition authorities.
