Behavioral economics has been a growing force in many fields of applied economics, including public economics, labor economics, health economics, and law and economics. This paper describes and assesses the current state of behavioral law and economics. Law and economics had a critical (though...

Exxon Shipping Co. v. Baker acknowledged that empirical studies undercut criticism of punitive damages.
