In this paper it is shown that, in presence of substantial underdeterrence caused by costly detection and punishment, these instruments may become complements. When offenders are poor, the deterrent value of monetary sanctions is low. Thus, the government does not invest a lot in detection. If offenders are rich, however, the deterrent value of monetary sanctions is high, so it is more profitable to prosecute them.application/pdfengL'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative CommonsOptimal magnitude and probability of finesinfo:eu-repo/semantics/workingPapercrimeprobability and severity of sanctionslaw enforcementBusiness Economics and Industrial Organizationinfo:eu-repo/semantics/openAccess
