Criminal personality profiling

In this work we examine outcome and process differences in criminal personality profiling among groups of profilers, detectives, psychologists, and students, using closed police cases—one sex offense and one homicide. Two major questions guide this research: (1) Are professional profilers more accurate than nonprofilers in generating personality profiles and correctly identifying offender features from crime scene details? and (2) Is the process that the profilers use qualitatively different from that of the nonprofilers? In the written profile task, the task that is most representative of what profilers actually do, profilers write richer, more detailed, and more valid profiles than the nonprofilers for both the sex offense case and homicide case. An analysis of correct responses concerning the known offender for the sex offense case revealed that the profilers scored significantly better than the other three groups in a variety of measures; similar results were not revealed for the homicide case. Profilers, however, do not appear to process this material in a way qualitatively different from any other group.     

Ownership versus competition: Efficiency in public enterprise

Certainly the introduction of product market competition into potentially competitive or, at least contestable, markets can improve performance. To take just one example, Morrison and Whinston (1986, 1986) estimate that even in the imperfectly contestable U.S. airline industry, the annual U.S. welfare gains from deregulation have been around $6 billion.But this paper argues, and further buttresses empirically, that ownership also matters and matters a lot. This does not necessarily imply that private ownership is always preferable to public ownership. PCs also engage in rent-seeking where possible, but they will try to maximize realizable rents by (relatively) keeping down production costs. Of course, where there are massive economies of scale and scope, high entry barriers, or externalities, public ownership may be preferred. (see Vickers and Yarrow, 1988).

Costs and benefits through bureaucratic lenses: Example of a highway project

This article characterizes the perceptions of government bureaucrats about cost-benefit analysis (CBA). The observations arise after working with government officials on various projects and leading many executive seminars for government employees over the last decade on the principles and practice of CBA. Government employees tend to adopt one of three conceptual lenses: Guardians, Spenders, and Analysts. These perspectives differ sharply from one another, resulting in completely different meanings to the words benefits and costs. The orientation of Guardians is to “revenue-expenditure” analysis, while Spenders are oriented to “constituency-support” analysis. Analysts are oriented to standard CBA. The differences in perspectives are illustrated using an ex ante CBA of a proposed toll highway project.
