Abstract
Behavioral economic analysis of law is about bringing recent research about behavior and choice together with
classical law and economics. In this essay we assess its relevance for the theory of optimal law enforcement. It is

far provided by the behavioral approach are somehow disappointing.

behavioral school presents an extremely important challenge to classical law and eco-
nomics. The development of experimental economics and choice theory has made pos-
sible for law and economics scholars to start looking at their own discipline with new
insights.1
Within the law and economics controversy, the economic approach to crime has been
one of the most challenged subjects. The skepticism towards economic research on crime
and criminal law has been widely expressed by criminologists and sociologists.2 On the
modeling of criminal behavior, the theory faces the usual criticism of the expected utility
framework and the usefulness of the assumption of economic rationality. It assumes that
the deterrence hypothesis (in fact no more than an application of the theory of demand)
is a reasonable explanation for some crimes: people respond significantly to the deterring
incentives created by the criminal justice system.
Classical law and economics is about behavior and efficiency. With respect to behavior,
the classical approach is of a particular sort: rational optimizing individuals. Criminals
