Behavioral differences in violence: the case of intra-group differences of paramilitaries and guerrillas in Colombia

In most studies on civil wars, determinants of conflict have been hitherto explored assuming that actors involved were either unitary or stable. However, if this intra-group homogeneity assumption does not hold, empirical econometric estimates may be biased. We use Fixed Effects Finite Mixture Model (FE-FMM) approach to address this issue that provides a representation of heterogeneity when data originate from different latent classes and the affiliation is unknown. It allows to identify sub-populations within a population as well as the determinants of their behaviors. By combining various data sources for the period 2000-2005, we apply this methodology to the Colombian conflict. Our results highlight a behavioral heterogeneity in guerrilla’s armed groups and their distinct economic correlates. By contrast paramilitaries behave as a rather homogenous group.

Psycological violence against women in Colombia

Although violence against women has gain attention, there is little evidence of studies about phycological violence against a partner. This paper uses data from Encuesta Nacional de Demografíay Salud (ENDS) to assess empirically models of violence against a partner. One of the main findingsis that the higher the economic independence of the women, the lower the phycologicalviolence against a partner. Some other results show that women with higher education level, belongingto a violent or low income family and living in cities different from Bogotá is correlatedwith higher probability of phycological violence.
