To reduce preventable readmissions, many healthcare systems are transitioning from Fee-for-Service (FFS) to other reimbursement schemes such as Pay-for-Performance (P4P) or Bundled Payment (BP) so that the funder of a healthcare system can transfer to the hospital some of the financial risks associated with patient re-hospitalizations. To examine the effectiveness of different schemes (FFS, P4P, and BP), we develop a "health co-production" model in which the patient's readmissions can be "jointly controlled" by the efforts exerted by both the hospital and the patient. Our analysis of the equilibrium outcomes reveals that FFS cannot entice the hospital and the patient to exert readmission-reduction efforts. Relative to BP, we find that P4P is more "robust" in the sense that it can induce readmission-reduction efforts under milder conditions. However, BP can induce greater efforts compared to P4P. More importantly, we characterize the conditions under which BP (or P4P) is the dominant scheme from the funder's perspective. Finally, we find that patient cost-sharing can generate two benefits: (a) it provides incentive for patients to exert efforts; and (b) if not excessive, it can reduce the readmission rate

Interfirm ties and knowledge transfer: The moderating role of absorptive capacity of managers

Through the lens of social capital perspective, this paper assesses how individuals' interactions and their learning capabilities explain the transfer of good practices in an interorganizational network. Primary data were collected from export consortia in Tunisia through a questionnaire survey. The research underlines the impact of the strength and the range of ties between managers. It is also found that managers' absorptive capacity moderates the impact of the strength of ties. This study considers the individual's behavior at the heart of the knowledge transfer process and suggests a substitution effect between the strength of social ties and individual's absorptive capacity

Leadership and the Logic of Absurdity


Academy of Management Review

A paraître

Départements : Management et Ressources Humaines

Leaders are often thought to be instrumental to the performance of the organizations they lead. However, considerable research suggests that their influence over organizational performance might actually be minimal. These claims of leader irrelevance pose a puzzle: If leaders are relatively insignificant, why would someone commit to leading? Applying decision-making theory, this paper first considers justifying the decision to lead according to the Logics of Consequence and Appropriateness—the two principal decision-making logics underlying previous work on the motivation to lead. The paper then presents the Logic of Absurdity, a decision-making logic in which decision-makers knowingly choose to dedicate themselves to an irrational course of action. In terms of the decision to lead, a decision-maker employing the Logic of Absurdity acknowledges the likely futility of leading but decides to commit to leading, nonetheless. The paper concludes by considering when leaders are most likely to decide to lead according to the Logic of Absurdity and why doing so may result in leadership of exceptional originality, foolishness, intelligence, and madness

Making a Niche: The Marketization of Management Research and the Rise of “Knowledge Branding”


Journal of Management Studies

Départements : Comptabilité et Contrôle de Gestion, GREGHEC (CNRS)

In this essay, we discuss an underexplored and consequential aspect of management scholarship that we term ‘Knowledge Branding’. Knowledge Branding refers to forms of market‐oriented work undertaken when creating, maintaining and developing niches of research. We consider some of the conditions and consequences of Knowledge Branding in the formation and expansion of management research sub‐fields, and then suggest how its more damaging effects might be mitigated.We invite participation in a ‘difficult conversation’ about the culture of market‐oriented knowledge production in management research, not only by raising uncomfortable questions about its grip on our field but also because we acknowledge our complicity in what we discuss. One of us (Hugh) has had an academic career spanning four decades, has been keenly observing the evolution of management scholarship, and has been questioning recent trends such as the commercialization and marketization of higher education, the commodification of academic labour, and the rise of managerialism evident in the use of performance measurement systems such as journal lists. At the same time, he has served on panels responsible for evaluating business and management research (e.g., the UK research evaluation exercises, RAE and REF). By associating funding more directly to short(‐ish) term performance metrics, such exercises are seen to have accelerated the marketization of research that we consider here. The other (Afshin) has started his academic career relatively recently. He has closely and personally experienced and observed the intensifying pressures upon Early Career Researchers (ECRs) to maximize ‘hits’ in ‘top’ journals that are fuelled by the importance placed by ‘consumers’ (students) and managers (deans, appointment and promotion committee members) on rankings of business schools and universities.Writing this essay was prompted by our reflections on the process of preparing and revising a paper for a special issue of Journal of Management Studies dedicated to ‘Political CSR’ (Scherer et al., 2016). Our participation in a number of workshops, conference sessions, and the review processes in relation to the preparation and revision of the paper led us to reflect in a more sustained way upon a process that we believe to be consequential in the rise of Political CSR, and that we characterize as Knowledge Branding. Based on personal experiences and discussions with a number of colleagues, we have come to believe that Knowledge Branding exerts an increasing influence in the formation and expansion of management research sub‐fields which we term Knowledge Brands (KBs). Examples with which we have more familiarity include ‘Political CSR’, ‘Strategy‐as‐Practice’, ‘Institutional Logics’ and ‘Institutional Work’. There are also methodological KBs, such as the ‘Gioia Methodology’, that cut across diverse sub‐fields. This list is by no means exhaustive and it would be surprising, in the context of intensifying competition to occupy the restricted spaces in ‘top’ journals, if the phenomena of Knowledge Branding and KBs were absent from other management sub‐disciplines (e.g., finance and marketing) or other fields of the social sciences.We are not taking issue with the disciplinarity of research in management and the lifecycle of sub‐disciplines that have been explored and debated extensively by others. Nor do we seek to reflect on the role of management academics (along with consultants and other professional groups) in developing and marketing managerial techniques and in giving rise to ‘management fashions’ (Abrahamson, 1996). Instead, our essay foregrounds the nature and effects of an intensification of market‐based organizing in the establishment and consolidation of management research sub‐fields. We do not suggest here that Knowledge Branding is a wholly new phenomenon. We do believe, however, that it is becoming more widespread and significant as an outcome, but also as a medium, of the intensification of market pressures and managerialism in our field. If our speculative observations resonate with our readers, then we hope that our sketch of Knowledge Branding will prompt more systematic scrutiny and evaluation of its operation and effects

Marking to Market and Inefficient Investment Decisions


Management Science

Départements : Finance

Mots clés : Marking to Market, Investment Decisions, Reputation, Agency Problem

We examine how mark-to-market accounting affects the investment decisions of managers with reputation concerns. Reporting the current market value of a firm's assets can help mitigate agency problems because it provides outsiders (e.g., shareholders) with new information against which the management's decisions can be evaluated. However, the fact that the assets' market value is informative can also have a negative side effect: Managers may shy away from investments that indicate conflicting private information and would damage their reputation. This effect can lead to inefficient investment decisions and make marking to market less desirable when market prices are more informative

Non-additivity in accounting valuation: Theory and applications

Mots clés : Choquet capacities, Goodwill, Growth options, Non-additive accounting-based valuation, Productive efficiency, Synergies

This paper has three objectives. First, to introduce a theoretical solution to the issue of non-additivity between assets in place, relying on an accounting-based valuation approach. Second, to explain how such an approach can be implemented empirically by measuring synergies between assets. Third, to present the properties of this non-additive valuation technique. We use Choquet capacities, that is, non-additive aggregation operators, to measure the interactions between assets and apply our methodology to a sample of US firms from the capital goods industry. To operationalize our approach we examine the relationships between synergies-captured by Choquet capacities-and the market-to-book ratio (proxying for growth options), and show how interactions between assets are consistently linked to a firm's market-to-book ratio. We also measure firm-specific productive efficiency relative to the industry and firm size. For large firms, efficiency, as defined by our approach, is positively associated with higher future operating cash flows. For small firms, efficiency is positively associated with higher future sales growth. We document that the non-additive approach appears to be better able to identify expected relationships between efficiency and future performance than a simpler approach based on the market-to-book ratio. © 2018 Accounting Foundation, The University of Sydney

Reinforcing the Public Law Taboo: A Note on Hellenic Republic v Nikiforidis


European Law Review

Départements : Droit et fiscalité, GREGHEC (CNRS)

Mots clés : mandatory rules, EU private international law, Rome I Convention, Rome I Regulation

This article hinges on the preliminary ruling rendered by the Court of Justice of the European Union (ECJ) (Grand Chamber) on 18 October 2016 and the related judgment of the German Federal Labour Court of 26 April 2017 in the Nikiforidis case to investigate an area of private international law that is undergoing a substantial development: overriding mandatory provisions. In Nikiforidis, the ECJ excluded that two Greek laws cutting the salary of public employees may be enforced against a teacher working in Germany for the Greek government under an employment contract governed by German law. The question addressed to ECJ was whether said laws were “overriding mandatory provisions” according to the Rome I Regulation. The court denied it, and left to the referring court to determine whether they could nevertheless operate “as matter of fact” under the governing law. This article explains how the ECJ’s conclusion has broader implications by regulating third countries’ interference in international business transactions. Starting with an analysis of the case, the article examines the history and nature of overriding mandatory provisions under EU private international law and argues that the solution embraced by the ECJ leaves room to uncertainty and unpredictability in the operation of foreign mandatory provisions
