On behalf of the interdisciplinary academic network MetaLawEcon, the EUI Law and Economics Working Group will organise a workshop on Economic Law and Economic Theory: Defining the Domain of “Law and Economics.” The aim of the workshop is to discuss how the relation between economic law and economics can be accounted for theoretically. It will also provide a forum for reflection on how this interaction plays out in (legislative, regulatory, judicial and academic) practice. A better understanding of the dynamic between economic law and economic theory not only contributes to a clearer semantics of the term “economic” but yields important insights about the potential and limitations of formulating Law and Economics as a distinct approach to law.
