Thesis advisor: Hideo Konishi / Becker (1968) provides a formal framework for analyzing various policies in criminal law. Within this framework there are potential criminals, who have varying benefits from committing an illegal act. They are subject to sanctions when they are caught and are found guilty for committing such acts. Accordingly, increased expected sanctions lead to greater deterrence. There are also costs associated with achieving such deterrence. Hence, there are optimal policy variables which balance costs and gains associated with increased deterrence. In my dissertation, in five independent but closely related essays, I address various issues related to criminal law by making use of optimal crime and deterrence models, which are similar to Becker (1968). First, I analyze the standard of proof in criminal trials and extend a justification as to why there are higher standards of proof in criminal trials versus civil trials. Next, I introduce the concept of mixed warning strategies, and justify the use of mixed as well as pure warning strategies in law enforcement. In a related essay, I show that it is optimal to punish repeat offenders more severely than first time offenders, provided that offenders gain experience in evading detection by committing offenses. In my fourth essay, I identify reasons as to why it is welfare improving to allow individuals to self-report conduct crimes. Finally, I propose a simple framework to incorporate the concept of remorse in the economic analysis of criminal law, and show that the Beckerian maximal fine result need not hold when some individuals feel remorse. / Thesis (PhD) — Boston College, 2010. / Submitted to: Boston College.

The basic purpose of this study was to investigate if placement in a cottage designated solely for juveniles involved in vocational training significantly improved the institutional adjustment and recidivism rate of institutionalized male juvenile delinquents. An additional purpose of the study was to investigate the effects of an involvement in a vocational training program on institutional and post release adjustment of institutionalized juvenile delinquents. Statistical analysis of the data supported the basic hypothesis that subjects who were involved in the vocational training, regardless of cottage placement, would adjust better to the institution. The two groups of vocational subjects had fewer admissions to the Discipline Cottage and a greater frequency of achievement of privilege-level status than did the group of subjects who did not receive vocational training. The hypothesis that vocational subjects who were housed in a separate cottage would adjust better to the institution than would the vocational subjects who were housed in the regular cottages was also supported. The vocational subjects who were housed separately had fewer escapes, fewer admissions to the Discipline Cottage, and a greater frequency of attainment of privilege-level status than either of the other two groups. The analysis also supported the hypothesis that recidivism rates would not be differentially affected by an involvement in the vocational program, regardless of the cottage placement.

The study investigated the application of the crime threat analysis process at station level within the Nelson Mandela Metro City area with the objective of determining inhibiting factors (constraints) and best practices. Qualitative research methodology was applied and interviews were conducted with crime analysts and specialised investigators/intelligence analysts. The research design can be best described as descriptive and explorative in nature. The crime threat analysis process embroils the application of various crime analysis techniques and the outcomes thereof intends to have a dual purpose of generating operational crime management information in assisting crime prevention initiatives and crime detection efforts, mainly focussing on the criminal activities of group offenders (organised crime related), repeat offenders and serial offenders. During the study it became evident that crime analysts understand and thus apply the crime threat analysis process indifferently, which impeded on the relevancy and the utilisation thereof as an effective crime management tool. / Criminology / M.Tech.
