This study tries to enlarge the scope of law and economics by providing an example that legal institutions do not only have short-run effects on present behavior by changing the cost-benefit relation of different actions but can also drive the evolution of preferences. Therefore, legal design has long-run effects on behavior which should not be neglected by legislators. The study presents a simple model of cooperation where only one party has the option to observe the outcome of joint efforts. While this party can pretend a failure of cooperation, the other party has the option to monitor its partner. The model considers resource variables and a psychological variable reflecting remorse in case of betrayal. Players are assumed to behave rationally according to given preferences, but preferences may change in the course of evolution. The results show that a 'good' design of legal institutions can crowd out 'bad' preferences.
