Délinquance juvénile : appartenance à une bande et comportement de récidive

Abstract : We insert into the economic standard model of crime a particularity of juvenile delinquency: the fact that in general juvenile offenders act as part of gangs. In this, we break with Becker's model, founded on the hypothesis that offenders are isolated, in order to set our research into the general framework of integrative theories. More precisely, the objective of our research is to study the influence of gangs on the decision of teenagers to commit and to repeat an offence. For that, we use a theoretical and an empirical analysis. Two main topics are covered in our theoretical section. The first objective is to explain the sociologists' result that juvenile gangs' members are more involved in delinquency. In this part, we use economic models, not yet used in economic theory of crime, and we show, with an original contribution that, in certain cases, that sanctions based on individual liability are inefficient to deter gang's members from delinquency. The second aim is to analyze whether the affiliation to a gang can have an effect on the career of delinquents. In the empirical section, we test the validity of our theoretical predictions by using an original database covering the judicial folder of 535 juvenile delinquents. Our results show the inefficacity of repressive policies in the context of gangs and encourage us to advise public authorities to apply other forms of policies to fight juvenile delinquency and juvenile relapse.
