Economic antecedents of foster care

Individual and ecological research suggests that rising unemployment may affect the incidence of violence through two countervailing mechanisms suggested by frustration-aggression theory. The first, or provocation effect, assumes increased violence among persons who feel anger because they believe their job loss was arbitrary. The second, or inhibition effect, posits less violence among employed persons who attempt to reduce their chances of job loss by curtailing behavior objectionable to employers. The literature also reports that these mechanisms affect victimization measured as foster care sought by the state for abused children. The foster care finding, although consistent with theory and important for basic as well as applied reasons, arises from methods that cannot rule out several rival hypotheses. We revisit this research and apply improved methods to test the reported association in Los Angeles and San Francisco counties. We find that, as implied by the provocation and inhibition mechanisms, differences in monthly prevalence of foster care placements increase with modest increases in unemployment but decline when unemployment becomes much higher than usual levels.
