Lois et normes : les enseignements de l’économie comportementale
This
paper discusses recent papers in experimental law and economics studying the
rela-tion between laws and social norms. Traditionally the law and economics
analysis of legal compliance focuses on the effectiveness of the legal system
in law enforcement. However, recent lab-experiments have shown that obligations
might affect behaviors by influencing expectations about others’ choices, thus
allowing the emergence of virtuous equilibria in games where social preferences
matter. Moreover, obligations might directly affect pref-erences. These results
have implications for the analyses of legal rules and regulation.
