A Welfare Assessment of Revenue Management Systems
No full textInternational audienceWe study the welfare impact of revenue management, a practice which is widely spread in the transport industry, but whose impact on consumer surplus remains unclear. We develop a theoretical model of revenue management allowing for heterogeneity in product characteristics, capacity constraints, consumer preferences, and probabilities of arrival. We also introduce dynamic competition between revenue managers. We solve this model computationally and recover the optimal pricing strategies. We find that revenue management is generally welfare enhancing as it raises the number of sales
RSE et Développement Local dans l'Industrie Pétrolière au Nigeria
No full textThe institutional theory of corporate social responsibility (CSR) argues that content and practice of CSR adapt to the institutional environment. In the oil industry in Nigeria, and more widely in developing countries where institutions work on a personalized mode, with a dominant coalition made of powerful elites manipulating rents and privileges to ensure stability, CSR also adapts. Using the crypto-morality concept, we demonstrate that in such institutional environments, CSR evolves according to both the detectability of corporate practices, and penalties that stakeholders impose to corporations. Therefore, the corporate contribution to local development as part of CSR aims mainly to meet legitimate and illegitimate expectations of the most influential stakeholders in order to protect company's operations.La théorie institutionnelle de la responsabilité sociétale des entreprises (RSE) soutient que le contenu et la pratique de la RSE s'adaptent à l'environnement institutionnel. Dans l'industrie pétrolière au Nigeria, et plus largement dans les pays en développement où les institutions fonctionnent sur un mode personnalisé avec une coalition dominante formée d'élites puissantes qui manipulent rentes et privilèges pour assurer la stabilité, la RSE s'adapte également. Nous démontrons, à l'aide du concept de crypto-moralité, que dans un tel environnement institutionnel, la RSE évolue en fonction de la détectabilité des pratiques de l'entreprise par les parties prenantes et des pénalités que ces dernières lui imposent. De fait, l'appui du développement local au titre de la RSE vise alors fondamentalement à répondre aux attentes à la fois légitimes et illégitimes des parties prenantes les plus influentes dans le but d'assurer la poursuite ininterrompue des opérations de l'entreprise
Boundary spanner relational behavior and inter-organizational control in supply chain relationships
No full textInternational audienceBoundary spanner relational skills are considered critical in the successful management of buyer-supplier relationships and may help avoiding high costs of more formal inter-organizational controls. Yet, the influence of partners' boundary spanners on effective supply chain collaboration has had much less inquiry than the influence of broader inter-organizational controls. We use survey data of 200 buyer-supplier relationships to examine how these individual and organizational control mechanisms influence the performance effects of interfirm collaborations that vary in scope of activities undertaken. Findings show that collaborative scope as well as boundary spanner relational skills and inter-organizational controls are positively associated with performance. The effect of collaborative scope on firm performance, however, also depends on both mechanisms but in opposite directions: while the influence of collaborative scope on performance is enhanced by inter-organizational controls, a partner's boundary spanner relational skills has a negative moderating effect, indicating that such skills contribute more to the effective management of collaborations of narrow scope than those of broader scope
Patient preference for chronic obstructive pulmonary disease (COPD) treatment inhalers: a discrete choice experiment in France
No full textInternational audienceObjectives: Understanding inhaler preferences may contribute to improving adherence in COPD patients and improving long-term outcomes. This study aims to identify and quantify preferences for convenience-related inhaler attributes in French moderate-to-severe COPD patients, with discrete choice experiment (DCE) methodology. Methods: Attributes were defined from a literature search, clinician and patient interviews: shape, dose insertion, dose preparation, dose release, dose confirmation, dose counter and reusability. An online DCE was conducted in respondents with self-reported COPD stage 2-4 recruited through a panel. The study questionnaire included twelve choice scenarios per respondent and questions on patient characteristics, treatment and disease severity. Statistical analyses used a mixed logit regression model with random effects. Utility scores were estimated for four types of inhalers: Inhaler Asoft mist inhaler; Inhaler Breusable soft mist inhaler; Inhaler Cmulti-dose dry powder inhaler; and Inhaler Dsingle dose dry powder inhaler. Results: The study was completed by 153 patients (50 females); respondents were 50.4 years old on average; 13 different inhaler devices were reported. The most preferred inhaler is L-shaped, has dose preparation with capsule insertion and a dose counter, and is reusable. Inhaler profiles A and B had the highest utilities (mean of 1.2533 and 0.9578 respectively) compared to inhaler C (0.6315) and D (0.2200). Conclusions: This study showed statistically significant results that the strongest drivers of preference in French users of inhalation devices for COPD are shape, dose counter and reusability. Conveniencerelated characteristics are important to patients and should be taken into account by clinicians prescribing these devices
How Serious is the Measurement-Error Problem in a Popular Risk-Aversion Task?
No full textThis paper uses the test/retest data from the Holt and Laury (2002) experiment to provide estimates of the measurement error in this popular risk-aversion task. Maximum likelihood estimation suggests that the variance of the measurement error is approximately equal to the variance of the number of safe choices. Simulations confirm that the coefficient on the risk measure in univariate OLS regressions is approximately half of its true value. Unlike measurement error, the discrete transformation of continuous riskaversion is not a major issue. We discuss the merits of a number of different solutions: increasing the number of observations, IV and the ORIV method developed by Gillen et al. (2019)
Evaluation of Big Data governance : combining a multi-criteria approach and systems theory
No full textInternational audienceThe main objective of Big Data is to meet business competitiveness and facilitate decision-making. To achieve this goal, the implementation of a governance plan is necessary. In this article, we propose a big data governance evaluation approach based on the fact that big data governance is seen as an artifact having the characteristics of a system. We develop a multi-criteria hierarchy organized according to the main dimensions of systems theory. The approach is illustrated on a practical case
Design science research for the humanities. The case of prosopography
No full textInternational audienceThe humanities focus on understanding human beings and cultures. They include such disciplines as history, literature, and the arts. Digital humanities, defined as the application of IT to research and teaching in the humanities, is well established as a field in its own right. More particularly, research in the humanities is in demand of innovative and useful IT artifacts. This makes it a relevant application area for design science research (DSR). This also raises specific challenges to DSR researchers, due to the specific stakeholders and knowledge domains that come into play in the digital humanities. This paper focuses on prosopography, a branch of digital humanities that represents and interprets historical data, sourced from texts describing historical person's life. Starting from typical issues addressed by prosopographical researchers, we identify relevant IT artifacts to address these issues, making DSR relevant for prosopographical research. We adapt and instantiate Hevner's DSR framework to the specific case of prosopography, as a first step towards defining a DSR framework for the humanities more generally. Based on this adapted and instantiated DSR framework, we propose two artifacts: requirements and a methodology for prosopography. We demonstrate the methodology on a prosopography scenario
Phantom Images in public sector accounting reform: A french study
No full textInternational audienceBased on the analysis of the decision to adopt accrual accounting by the French State, this study emphasizes the trajectory of this innovation, from the first debates around this idea in the 1980s to its introduction in the LOLF in 2001. Relying on the Actor-Network-Theory (ANT) framework, this study presents the birth of the need for this public sector reform, the progressive construction of a network of actors supporting it and the controversies raised. This case study shows the importance of phantom images in justifying the reform, leading to the conclusion that beliefs are as important as hard facts. It also highlights how the concrete idea of what would be accrual accounting in France was only defined at the end of the innovation process, when the adoption of accrual accounting was already irreversible
Managerial Behavior in the Lab: Information Disclosure, Decision Process and Leadership Style
No full textThis paper reports the results from a lab experiment in which subjects playing the manager role can implement either an efficient / inegalitarian allocation or an inefficient / egalitarian allocation of payoffs. The experiment simulates a stylized managerial context by allowing the manager to manipulate information and select the decision process and by allowing the stakeholders to retaliate against the manager given different choices in the decision process. We found that the inefficient allocation is often selected and that this choice depends on whether the employees can retaliate against the manager and on whether the manager can hide information about the payoffs. The social preferences of the manager also explain the choice of the option. However, the decision process and the managerial style based on self-reported attitudes have little influence on the choice of allocation. This is consistent with employee satisfaction essentially depending on the payoff and not being sensible to the process
The Role of Artifacts in Institutionalization Process: Insights from the Development of Socially Responsible Investment in France
No full textInternational audienceLeca, Dejean, Huault and Gond investigate how actors engage in institutional work through artefacts and how those artefacts contribute to the institutionalization of new practices. Building on an analysis of the early stages of the institutionalization of socially responsible investment (SRI) in France, they highlight three effects of artefacts as enabling, constraining and entangling practices. They also use the case study as an opportunity to sketch out an integrative approach to artefacts consistent with the tenets of institutional theory. It further sheds light on the relations between artefacts, discourse and practices in institutional processes
