Abstract
Objectives This study proposes a theoretical framework for understanding two empirical
findings from gang research: (1) gangs are generally racially homogenous, even in
heterogeneous environments, and (2) gang violence tends to be intra-racial. We draw from
the extensive literature on street gangs as well as from research on group formation and
status-enhancing behavior to develop a theoretical model of gang formation.
Methods Using game theory, we model the simultaneous decisions of individuals to
commit status-enhancing acts of violence and to seek protection by joining a gang. We
then conduct computer simulations to examine the resulting patterns of violence and gang
composition.
Results We demonstrate that as long as some social distance exists between racial groups
in a community, gang violence will be intra-racial and gangs will be homogenous. We find
that our results are robust to a number of simple variations of the model and allow us to
generate several hypotheses about the nature of gang formation and patterns of violence.
Conclusions When violence is motivated by socially constructed rewards, socially closer
targets are likely to yield greater rewards. In such a system, individuals must reduce their
likelihood of victimization by entering a social contract of non-violence (i.e. gang mem-
bership) with individuals who might view them as status-enhancing targets (i.e. socially
close individuals). The result is that gangs are made up of socially close individuals
interested in attacking other socially close individuals. Therefore, gangs tend to be racially
homogenous and violence is overwhelmingly intra-racial.
