Unemployment and the homicide rate: A paradox resolved?

The heretofore perplexing relationship between the unemployment and homicide rates is reevaluated through a dynamic, macro social indicator model of the postwar United States. Whereas prior research has failed to demonstrate consistently an empirical connection between economic conditions and crime rates, it is shown here that when attention is given to both the level of unemployment and recent changes in unemployment, the relationship between the unemployment rate and the homicide rate becomes more intelligible. The level of unemployment is negatively related to the homicide rate while annual changes in unemployment are positively related to the homicide rate. These paradoxical effects of unemployment remain even after controlling for other theoretically-relevant variables. Interpretation of the results revolves around the dichotomy of motivation and opportunity as components of human behavior.
