An exploratory study of the management of product replacement

The process of product replacement is a surprisingly neglected area of innovation. Its existence as an important corporate activity is known through prior research and anecdotal evidence. This study was designed to shed some light on the replacement activities which are conducted by large companies in Britain and America. The findings revealed a number of different approaches to product replacement and suggested that related activities can be understood (and measured) by seven distinct dimensions.     

ExpertLens: A system for eliciting opinions from a large pool of non-collocated experts with diverse knowledge

The complexity of policy decision-making raises the need to elicit opinions from large and heterogeneous groups of stakeholders with broad and diverse sets of expertise. Existing options for elicitation include small face-to-face panels of experts by using the Nominal Group Technique (NGT), large Delphi panels whose members do not interact with each other face-to-face, and crowdsourcing, which involves an open call for input issued to a large community of people. In an attempt to close the gap between the practical needs of policy makers and the methodological challenges associated with eliciting opinions of large, diverse, and distributed groups, we have developed a new online elicitation system and methodology called ExpertLens. By optimizing the direct interactions of NGT with the larger number of Delphi participants and the wisdom of “selected crowds,” our approach is designed to save on the costs associated with traditional expert panels, while increasing accuracy in elicitation by reducing the potential for group process losses that can occur in large, diverse, and non-collocated panels whose members interact via asynchronous online discussion boards. The ExpertLens approach is iterative, does not require participants to develop consensus, and determines what the group “thinks” by statistically analyzing data collected in all rounds of the elicitation. This paper describes the ExpertLens system and methodology, briefly discusses recent ExpertLens trials, provides conceptual arguments for why it is an appropriate model for eliciting expert opinions, illustrates its main components and analytics by using an infrastructure investment example, and discusses a research agenda for testing the underlying tenets of the ExpertLens approach.     

Implementing the Mortensen rule in a frictional labor market

We show that, in settings where meetings can be multilateral, the allocation rule proposed by Mortensen (1982) can be relatively straightforward to implement: as a local auction conducted by sellers. The implications of using this mechanism in a simple model of the labor market are then explored. We characterize the equilibrium properties of this model, which include wage dispersion, and examine its implied Beveridge curve. A dynamic version of the model is calibrated to the US labor market, and we show that the model can account for observed vacancy rates, given parameters that are chosen to match the average wages and the natural rate of unemployment, although the implied wage dispersion is quite small. Finally, in the limit, as the time between offer rounds in the model approaches zero, the equilibrium approaches the Walrasian competitive equilibrium.     

Pushing on a String: How policy might encourage private doctors to compete with the public sector on the basis of quality

Results from the Philippine Quality Improvement Demonstration Study show that a policy that expands insurance coverage improves quality of care, as measured by clinical performance vignettes, among public physicians, and induces a spillover effect that improves quality among private physicians.     

Making public transport financially sustainable

Over the past two decades, Germany has improved the quality of its public transport services and attracted more passengers while increasing productivity, reducing costs, and cutting subsidies. Public transport systems reduced their costs through organizational restructuring and outsourcing to newly founded subsidiaries; cutting employee benefits and freezing salaries; increasing work hours, using part-time employees, expanding job tasks, and encouraging retirement of older employees; cooperation with other agencies to share employees, vehicles, and facilities; cutting underutilized routes and services; and buying new vehicles with lower maintenance costs and greater passenger capacity per driver. Revenues were increased through fare hikes for single tickets while maintaining deep discounts for monthly, semester, and annual tickets; and raising passenger volumes by improved quality of service, and full regional coordination of timetables, fares, and services. Those efforts by public transport agencies were enhanced by the increasing costs and restrictions on car use in German cities. Although the financial performance of German public transport has greatly improved, there are concerns of inequitable burdens on labor, since many of the cost reduction measures involved reducing wages or benefits of workers.     

A Natural Resource Scarcity Typology: Theoretical Foundations and Strategic Implications for Supply Chain Management

World population growth and increased consumption stemming from economic leveling are leading to scarcity of a number of natural resources on a global scale. Scarcity of critical natural resources such as oil, water, food, and precious metals has the potential to greatly impact commercial activity as the twenty‐first century progresses. The challenge of continuing to provide needed goods and services in the face of these constraints falls to supply chain managers, who are ultimately responsible for delivering utility to customers. Unfortunately, there has been almost no research focused on supply chain strategies aimed at mitigating natural resource scarcity’s (NRS) potential effects. The current research positions NRS as a supply chain risk and proposes an NRS typology based on key resource attributes. Supply chain mitigation strategies to counter each resource status are offered, with an overall objective of improving supply chain performance. The study recommends future research aimed at further developing theory and methods for countering NRS based on resource, systems and behavioral theories. In addition, this study has critical implications for practitioners faced with the growing threat of NRS in their supply chains.     

East Asian Scholarly Research: A View from the 94th Floor

This article examines both applied and academic research relating to East Asia published during 1994 in terms of its applied relevance and its contributions to existing theory. In recent years the volume of research related to East Asia has expanded rapidly, and this review looks at the hightlights of that literature. Research from each of the functional business areas is examined, both in terms of its current and future contributions. In addition, special attention is paid to the areas of strategic management and entrepreneurship, which had a large amount of important research published during this period. Finally, there is an overall assessment of the impact of this research.
