The pits and the core: Simple collective decision problems with concave preferences

This essay extends the theory of simple collective decision problems to spatial games in which (contrary to the traditional assumption) each agent's preferences are concave, in the sense that the alternatives that the agent does not prefer to any particular reference alternative together constitute a convex set. Such concave preferences might characterize decision problems in which, say, a site must be selected for some obnoxious facility, such as a prison, garbage dump, or facility for managing hazardous materials. The results indicate that, under these conditions, the (weak -)core can be structurally unstable, changing discontinuously with apparently minor perturbations of the decision problem. The main theorem identifies a curious property of the core when the set of feasible alternatives is compact and convex and each agent's preferences are strictly concave. Namely, a point in the feasible set's interior can belong to the core only if there is no feasible alternative that makes every member of any winning coalition strictly worse off. In this sense, an interior point belongs to the core only if it lies in the pits.A preliminary version of this essay was presented at the West Coast Conference on Small Groups Research, Stanford University, 17 April 1985, and the Experimental Social Choice Workshop, Utah State University, Logan, Utah, 20–21 June 1985.

Summonsing Criminal Desistance: Convicted Felons’ Perspectives on Jury Service

This exploratory study is the first to examine how convicted felons view the jury process and their role in that process. Data derived from interviews with former and prospective felon‐jurors in Maine, the only US jurisdiction that does not restrict a convicted felon's opportunity to serve as a juror, reveal that participants displayed an idealized view of jury service, stressing a commitment to serve conscientiously. Additionally, inclusion in the jury process affirmed their transitions from “offenders” to “nonoffenders.” In response, participants exhibited a sense of particularized self‐worth, emphasizing that negative experiences with the criminal justice system make one a more effective juror. In sum, this study suggests that among convicted felons, inclusion in the jury process may prompt conformity with the “ideal juror” role, facilitate prosocial identity shifts by mitigating the “felon” label, and help former offenders to find personal value.     

Evaluation of the south carolina comr/cunity long-term care medicaid waiver for the elderly and disabled

Medicaid waivers play an important role in the health policy process. Various health care policy initiatives have encouraged states to experiment ith their Medicaid programs by expanding coverage to populations not traditionally covered by Medicaid, or by delivering Medicaid services in non traditional ways. Lessons learned by individual states' Medicaid waivers could be an important part of the health care reform debate. This paper presents an evaluation of a Medicaid waiver operating in South I Carolina. The South Carolina Community Long-term Care Waiver for the Elderly and Disabled is evaluated for cost effectiveness, quality of care, and client satisfaction. This evaluation shows that the waiver is highly effective in offering individuals who are medically and financially eligible for Medicaid supported nursing home care a viable, cost effective, high quality alternate to institutionalization.     

Incorporating skill development into the MPA curriculum

This article recommends that MPA Programs not already doing so consider two ideas. First, explicitly include skill development as an important program objective. Second, use the strategy of incorporating skill development and reinforcement into existing courses rather than adding new courses. A process for identifying skills and deciding where to locate them in the curriculum is presented. A list often generic skills is suggested along with a discussion of how they might fit within an MPA core curriculum.     

The Global Information Infrastructure Revisited

Ideally, the internet will eventually evolve into a global information infrastructure, which, by creating a global information marketplace, will narrow the poverty gap and eliminate many of the existing geographic barriers to prosperity and equality. On the other hand, there is a risk that the internet will concentrate economic activity among the richer countries and thus accentuate the existing divisions between North and South. Which of these scenarios is the more likely will depend to a large extent on whether developing countries are able to gain access to low-cost forms of information technology. Using numerous examples of such technology that already exist in the Third World, we conclude that there is in fact more scope for optimism regarding the Global Information Infrastructure than is commonly realised.
