The volume focuses on the question of how the results on consumer behaviour can be used in EU consumer law. Behavioural studies have shown that consumer behaviour features certain traits that only follow rational and information-based approaches to a limited extent. In this volume, renowned authors from various EU Member States have examined the extent to which consumer law should react to the results of behavioural studies. Does the legal notion of the consumer have to be changed and centred on a person who acts merely perfunctory and is easily influenced? Should the law continue to use information as a main instrument of protection? Are more mandatory rules needed or should private autonomy remain paramount? Does the law have to stimulate certain behaviour, such as to motivate consumers to enforce their rights?
