Liu et al. on Key Players in Criminal Networks

Xiaodong Liu Eleonora Patacchini Yves Zenou and Lung-Fei Lee (University of Colorado at Boulder - Department of Economics , Università di Roma "La Sapienza" , Stockholm University and Ohio State University (OSU) - Department of Economics) have posted Criminal Networks: Who is the Key Player? on SSRN. Here is the abstract:

We analyze delinquent networks of adolescents in the United States. We develop a dynamic network formation model showing who the key player is, i.e. the criminal who once removed generates the highest possible reduction in aggregate crime level. We then structurally estimate our model using data on criminal behaviors of adolescents in the United States (AddHealth data). Compared to other criminals, key players are more likely to be male, have less educated parents, are less attached to religion and feel socially more excluded. We also find that, even though some criminals are not very active in criminal activities, they can be key players because they have a crucial position in the network in terms of betweenness centrality.
