Nudging in private international law: the design of connecting factors in light of behavioural economics

Journal article

Amending the traditional economic analysis of law and its assumption of rationality, this paper suggests that behavioural economics can inform a more realistic understanding of private international law, which has been missing to date. Acknowledging the psychological biases which private parties are facing when dealing with complex cross-border cases, the paper introduces a new perspective on the design of connecting factors in EU private international law which are to be conceived as nudges that steer the applicable law and international jurisdiction to counteract bounded rationality. Objective connecting factors can be perceived as default rules, whereas the framework for exercising party autonomy can be construed as choice architecture of subjective connecting factors. Revealing the underlying libertarian paternalism of connecting factors requires addressing existing concerns about nudging, which is insightful for establishing the requirements of a transparent and choice-preserving design. Behavioural economics prove to be particularly suitable for explaining the restriction of choice and other connecting factor modifications for consumer protection in private international law.
