Objectives Investigate how different model assumptions have driven the conflicting findings in the literature on the deterrence effect of capital punishment. Methods The deterrence effect of capital punishment is estimated across different models that reflect the following sources of model uncertainty: (1) the uncertainty about the probability model generating the aggregate murder rate equation...

D eterrence is based on the notion that people consciously try to avoid pain and seek pleasure. It follows that by making a choice painful enough—such as the choice of crime—individuals will choose not to engage in the act. Across society as a whole, this perspective would predict that crime rates would be lowest in those places where offending evokes the most “pain” (or costs) and highest in t...

This paper puts forward the view that the life-cycle model of system development has been allowed to make the transition from a useful intellectual tool for discussing specific aspects of the process to a definitive statement of what the process actually “is”. We argue that this hinders the discussion of Requirements Engineering in fundamental ways, and that challenges to the supremacy of this ...

The common argument against the inclusion of pharmacists is the dynamics of the healthcare system, and ...

This article introduces technology choice into a Hotelling model of spatial competition. This yields two entry deterrence devices, as well as complex strategic choices for the firms and a rich picture of industry structure. Depending on cost parameters and market size, firms may choose to over-invest or to under-invest. Industry structure is typically asymmetric either in terms of the locations...
