We investigate the effects of job displacement, as a result of mass layoffs, on criminal arrests using a matched employer-employee crime dataset from Medellín, Colombia. Job displacement leads to immediate and persistent earnings losses and higher probability of arrest for both the displaced worker and family members. Leveraging a banking policy reform, we find that greater access to credit attenuates the criminal response to job loss. Impacts on arrests are pronounced for property crimes and among younger men for whom opportunities in criminal enterprises are prevalent. Taken together, our results are consistent with economic incentives contributing to criminal participation decisions after job losses.
