Cross-national analysis reveals how economic factors shape the suicide-homicide ratio, suggesting economic conditions direct rather than merely generate lethal violence.
This research examines the utility of the stream analogy of lethal violence. Based on frustration/aggression thesis and attribution thesis, expanded integrated models of total lethal violence and the suicide-homicide ratio are proposed. Using updated cross-national data, the results of regression analysis indicate that income inequality and economic development remain to be the predictors for the direction of lethal violence expressed as suicide, as the stream analogy predicts, after the divorce rate and unemployment rate are controlled for. The authors’ data also reveal that the divorce rate greatly increases the total amount of violence but does not influence the percentage of lethal violence that is expressed as suicide over homicide.
