7 Theory says International migration World systems theory may be most applicable Economic/socio-cultural cultural integration 7

8 Theory says International migration World systems theory may be most applicable Economic/socio-cultural cultural integration Theory on crime in and of itself (Neapolitan 1997) Modernization theory, opportunity theory, dependency theory, culture/historic traditions, micro-level factors 8

9 Theory says International migration World systems theory may be most applicable Economic/socio-cultural cultural integration Theory on crime in and of itself (Neapolitan 1997) Modernization theory, opportunity theory, dependency theory, culture/historic traditions, micro-level l factors U.S. migration more strongly predicted by violence than economic conditions (Lundquist and Massey 2005) Violence as proxy for political motivations 9
