Using secondary data from 99 countries and IT impact literature as the guiding theoretical perspective; we examine the payoffs from e-government in the form of national performance. We do this by initially examining the relationship of e-government development with the first order government process efficiency parameters (resource spending efficiency and administrative process efficiency). Subsequently we examine the association of these first order efficiency outcomes with the two second order dimensions of national performance (reduction of social divide and business competitiveness). Our analysis reveals significant association of ‘e-government development’ with both the first order ‘government efficiency parameters’. Further analysis reveals significant relationships of ‘government efficiency parameters’ with thedimensions of ‘national performance’. Important role of ‘national business competitiveness’ in the reduction of ‘social divide’ is brought forth through post-hoc analysis. Through this research, we make some important contributions which have implications for researchers, practitioners, public administrators, and policy makers

Eliciting Gul's theory of disappointment aversion by the tradeoff method

Gul's theory of disappointment aversion (DA) has several attractive features, being intuitive, analytically tractable, and parsimonious. In spite of this, the DA model has received little attention in practical applications, which may be partly due to the absence of a procedure to elicit the model. We show how the tradeoff method, developed by Wakker and Deneffe can be used to elicit DA. Our elicitation method is parameter-free: it requires no assumption about utility and/or disappointment aversion. Quantitative tests of DA in three outcome domains, monetary gains, monetary losses, and life-years, suggest that the DA model is too parsimonious. Of the other models of disappointment aversion that have been proposed in the literature, our data are most consistent with the model of Loomes and Sugden

Enjeux et opportunités de l'executive education

La formation continue des managers et dirigeants, ou executive education, constitue aujourd'hui un des piliers de la stratégie des business schools. Peu présentes dans ce secteur jusque dans les années 1980, elles cherchent à y gagner des parts de marché par rapport aux sociétés privées, en s'appuyant notamment sur leur activité de recherche, qui constitue un avantage concurrentiel majeur. A condition qu'elles sachent favoriser des recherches à la fois rigoureuses sur le plan scientifique et pertinentes surle plan pragmatique, les business schools peuvent bénéficier d'un véritable effet vertueux de l'executive education, les profits économiques, culturels et symboliques associés se renforçant mutuellement.

Facility Reliability Issues in Network p-Median Problems: Strategic Centralization and Co-location Effects

M. MENEZES, O. Berman, D. Krass

Operations Research

mars-avril 2007, vol. 55, n°2, pp.332-350

Départements : Informations Systems and Operations Management


In this paper we analyze a facility location model where facilities may be subject to disruptions, causing customers to seek service from the operating facilities. We generalize the classical p-Median problem on a network to explicitly include the failure probabilities, and analyze structural and algorithmic aspects of the resulting model. The optimal location patterns are seen to be strongly dependent on the probability of facility failure - with facilities becoming more centralized, or even co-located, as the failure probability grows. Several exact and heuristic solution approaches are developed. Extensive numerical computations are performed

Favoriser l'innovation radicale dans une entreprise multidivisionnelle. Discussion du modèle ambidextre à partir de l'analyse d'un cas

Le modèle d'organisation ambidextre constitue l'une des réponses avancées par la littérature pour développer des innovations radicales dans les grandes entreprises. Il met en avant la coexistence d'unités dédiées à l'exploration et d'autres à l'exploration et au développement de ces innovations. L'articulation de ces unités, à la fois séparées et intégrées. a été peu étudiée. Sur la. base d'une étude longitudinale d'une nouvelle unité organisationnelle créée pour favoriser l'innovation dans une grande entreprise multidivisionnelle, nous caractérisons plusieurs modes d'intégration situés à des niveaux différents ct fondés sur des mécanismes variés.

As the business environment becomes more global and competitive, organizations need to pay more managerial attention to systematically encouraging business innovation. Singapore-based YCH Group, a leader in end-to-end supply chain solutions in the Asia-Pacific region, has addressed the issue of stimulating business innovation. This article describes its experiences and offers three lessons for encouraging IT-based innovation. The first lesson is to foster an innovation mindset, which YCH has done by creating an IT-centric innovation mindset and by balancing strategic and operational issues. The second is to build partnerships, which YCH has achieved by developing an outward-facing IT organization, by leveraging cross-learning from alliances, and by leveraging IT to capitalize on opportunities to grow with customers. The third lesson is to mitigate risks and uncertainty, which YCH has done by instilling a flexible risk ethic, by focusing on customer value when assessing its innovation projects, and by paying attention to protecting intellectual property.

From Flexibility to Insecurity: How Vertical Separation Amplifies Firm Level Uncertainty

This article presents a model where firms may endogenously externalize part of their production process. We start from the premise that adaptation to uncertainty cannot be contracted upon in the worker/employer relationship. Vertical separation then balances flexibility gains against hold-up costs of opportunistic behavior by outside contractors. In equilibrium, the degree of separation is shown to depend on the degree of product market competition, contractor's bargaining power, and the volatility of demand shocks. Our main result is that an increase in the degree of vertical separation amplifies the elasticity to demand shocks of firms' sales and employment. It does not, however, amplify aggregate uncertainty. Evidence from firm-level data is shown to be largely consistent with the main implications of our theory
