Herding with collective preferences

This paper studies a simple model of observational learning where agents care not only about the information of others but also about their actions. We show that despite complex strategic considerations that arise from forward-looking incentives, herd behavior can arise in equilibrium. The model encompasses applications such as sequential elections, public good contributions, and leadership charitable giving.     

Illicit drug use among arrestees, prices and policy

Prior studies, by relying on nationally representative surveys, have overlooked the important fact that use of addictive substances is not uniformly distributed; subgroups of hardcore users account for most of the drug consumption. This study employs the Arrestee Drug Abuse Monitoring system to analyze the demand for cocaine and heroin by urban arrestees, employing objective indicators of use based on urinalysis. The data are repeated city cross sections, and panel data methodology is employed to account for endogeneity. Cocaine and heroin prices have a negative effect on the probability of use even among this group of heavy users. Results indicate that subjective, self-reported measures of participation are likely to be under-reported, which may impart bias to estimates of the price elasticity. The own-price cocaine participation elasticity is about −0.15, and the own-price heroin participation elasticity is about −0.10 for arrestees. This contemporaneous elasticity understates the full effect, and the long-run price elasticity is about twice the magnitude. The magnitude of the price response is substantially smaller relative to the estimates in the prior literature, and calculations suggest that further enforcement and interdiction-driven increases in drug prices may not be cost-effective.     

From Partners to Players: Extending the HR Playing Field

HR professionals must always be “becoming” or constantly changing and adapting. For the last decade, many have argued the business partner role as a complement to traditional HR administrative work. We argue in this paper that HR professionals should move beyond partners to become players. HR professionals as players are “in the game, on the field, making a difference” through their HR work. In this article, we suggest that to become players, HR professionals must learn to coach, architect, build, facilitate, lead, and provide a conscience to business leaders. Specific knowledge and tools for each of these roles are described. © 2001 John Wiley & Sons, Inc.     

Some 'real' problems of 'virtual' organisation

This paper presents an ethnographic study of organisational change in a retail bank considering issues surrounding the supposed emergence of the 'virtual organisation'. It outlines emerging problems in organisational work as a consequence of the shift toward 'virtuality' and questions the explanatory value of such theoretical stances.     

By the teeth: A critical examination of James Scott's The moral economy of the peasant

Peasant households in Southeast Asia and elsewhere live on the margin of subsistence. Their survival strategies make them technological conservatives and weavers of reciprocal webs of social obligation and dependence. James C. Scott has argued that the fabric of this “moral economy” both guarantees subsistence for the peasants and forms the touchstone on which their judgements of social justice are tested. When those who should offer succor withdraw it, peasants are outraged and from their anger springs peasant rebellion. Two South Asian peasant rebellions of the 1940s (Telengana and Tebhaga) fail to support Scott's account and raise major questions about his historical method. Two others case studies focused on the early years of colonial contact (the Padri Wars and the capitalist transformation of the Kaveri delta) lead the authors to question sharply the existence of a “moral economy of the peasant” and to suggest that Scott has inadvertently presented a landlord's view of peasant society.     

The (Price) Core of a Bertrand–Edgeworth Economy

In this paper, a solution concept from cooperative game theory is applied to a special kind of oligopolistic markets. Traditionally, oligopoly theory uses non-cooperative game theory. The cooperative solution concept, the Price Core, has been specially developed for this paper. In contrast to the Core, in the Price Core, different consumers may pay different prices for the same commodity. An example shows that the set of competitive allocations may be a proper subset of the Core and that the Core may be a proper subset of the Price Core.

Interactive visualization of 3D mantle convection

The current availability of thousands of processors at many high performance computing centers has made it feasible to carry out, in near real time, interactive visualization of 3D mantle convection temperature fields, using grid configurations having 10–100 million unknowns. We will describe the technical details involved in carrying out this endeavor, using the facilities available at the Laboratory of Computational Science and Engineering (LCSE) at the University of Minnesota. These technical details involve the modification of a parallel mantle convection program, ACuTEMan; the usage of client–server socket based programs to transfer upwards of a terabyte of time series scientific model data using a local network; a rendering system containing multiple nodes; a high resolution PowerWall display, and the interactive visualization software, DSCVR. We have found that working in an interactive visualizastion mode allows for fast and efficient analysis of mantle convection results.     

CRM analytics: The fuel for the engine

How often are there articles about customer relations (CRM) in the press today? Almost as many as there were about Year 2000 last year! How many companies state that the customer is king but can do or are doing anything about this? Few really attempt to improve or build relationships with customers or increase their product holdings; treating a customer as an individual and not just another record is still rare. The opinion in many companies seems to be that they can buy a system to deliver what is needed, which is true, but the system is only as good as the rules that drive it, hence the emergence of CRM analytics. This paper aims to illustrate to the reader how a company can start to apply CRM from an analytical rather than from a purely technological angle.     

Experience,change and vulnerability: consumer education for older people revisited

Everyday consumer transactions have the same potential for unexpected consequence whatever the age of the consumers involved. Young and old alike can find that products and services fail to live up to performance claims and that they are left with problems not easily resolved, or costs that are difficult to recover. While not overlooking consumer heterogeneity – especially on the basis of age – older consumers are arguably distinguishable in terms of the social and financial context in which they make decisions and attempt to redress problems. In 1988, attention was drawn to the need for consumer education to look beyond generic objectives to the specific situation of older people and their transactions. More than a decade later, in an allegedly consumer‐oriented society, the issue is revisited here to assess the argument's current relevance. Despite the increased availability of information for decisions and consumer protection, difficulties persist in the way information is presented or accessed. Chameleon‐like, old problems become manifest in new unfamiliar ways and invalidate experience. Consumer education today is as important as it was in 1988. Arguably, technological change means that the need for a better understanding of dangers, rights and redress procedures is greater than ever and the needs of older people in increasingly complex private and public sector transaction environments are all the more pressing. However, a fundamental revision of the way we approach the design of products, services and environments is needed to improve prospects for older consumers.
