Classical deterrence theory revisited: An empirical analysis of Police Force Areas in England and Wales

The severity, certainty and celerity (swiftness) of punishment are theorised to influence offending through deterrence. Yet celerity is rarely included in empirical studies of criminal activity and the three deterrence factors have never been analysed in one empirical model. We address this gap with an analysis using unique panel data of recorded theft, burglary and violence against the person for 41 Police Force Areas in England and Wales using variables that capture these three theorised factors of deterrence. We find that the three factors affect crime in different ways. Increased detection by the police (certainty) is associated with reduced theft and burglary but not violence. We find that variation in the celerity of sanction has a significant impact on theft offences but not on burglary or violence offences. Increased average prison sentences (severity) reduce burglary only. We account for these results in terms of data challenges and the likely different motivations underlying violent and acquisitive crime.
