The resistible rise of Bayesian thinking in management: Historical lessons from Decision AnalysisJournal of Management 41 (2): 441-470. 2015.This paper draws from a case study of Decision Analysis – a discipline rooted in Bayesianism aimed at supporting managerial decision making – to inform the current discussion on the adoption of Bayesian modes of thinking in management research and practice. Relying on concepts from the Science, Technology and Society field of study, and Actor-Network Theory, we approach the production of scientific knowledge as a cultural, practical and material affair. Specifically, we analyze the activities de…Read more

79Ambiguity Aversion in the Field of Insurance: Insurers' Attitude to Imprecise and Conflicting Probability Estimates (review)Theory and Decision 62 (3): 219-240. 2007.This article presents the results of a survey designed to test, with economically sophisticated participants, Ellsberg’s ambiguity aversion hypothesis, and Smithson’s conflict aversion hypothesis. Based on an original sample of 78 professional actuaries (all members of the French Institute of Actuaries), this article provides empirical evidence that ambiguity (i.e. uncertainty about the probability) affect insurers’ decision on pricing insurance. It first reveals that premiums are significantly …Read more

1What do we mean by performativity in organization studies? A review of the literatureInternational Journal of Management Reviews (xx). 2015.John Austin introduced the formulation ‘performative utterance’ in his 1962 Book How to Do Things with Words. This term and the related concept of performativity have subsequently been interpreted in numerous ways by social scientists and philosophers such as Lyotard, Butler, Callon or Barad, leading to the coexistence of several foundational perspectives on performativity. This paper reviews and evaluates critically how organization and management theory (OMT) scholars have used these perspecti…Read more

1Performativity: Towards a performative turn in organisational studiesIn Raza A. Mir, Hugh Willmott & Michelle Greenwood (eds.), The Routledge Companion to Philosophy in Organization Studies, Routledge. pp. 508-516. 2015.Since John Austin introduced the expression “performative utterance” in 1962, the concept of performativity has been subjected to multiple translations by social scientists and philosophers such as Derrida, Butler, Callon, Barad or Lyotard, and each of its sequels has nurtured the development of organizational theory. This chapter provides an account of performativity emergence in Austin’s philosophy of ordinary language and traces the development of four conceptualizations of performativity tha…Read more

32Are individuals more risk and ambiguity averse in a group environment or alone? Results from an experimental studyTheory and Decision 78 (3): 357-376. 2015.Most decision-making research in economics focuses on individual decisions. Yet, we know, from psychological research in particular, that individual preferences can be sensitive to social pressures. In this paper, we study the impact of a group environment on individual preferences for risky and ambiguous prospects. In our experiment, each participant was invited to make a series of lottery-choice decisions in two different conditions. In the Alone condition, individuals made private choices, wh…Read more

Rational decision making as performative praxis: Explaining rationality’s éternel retourOrganization Science 22 (3): 573-586. 2011.Organizational theorists built their knowledge of decision-making through a progressive critique of rational choice theory. Their positioning towards rationality however, is at odds with the observation of rationality persistence in organizational life. This paper addresses this paradox. It proposes a new perspective on rationality that allows the theorizing of the production of rational decisions by organizations. To account for rationality’s éternel retour, we approach rational decision-mak…Read more

62The impact of governmental assistance on insurance demand under ambiguity: a theoretical model and an experimental test (review)Theory and Decision 75 (2): 153-174. 2013.This article deals with the impact of governmental assistance on insurance demand under ambiguity, i.e., in situations where probabilities are uncertain. First, using a model of insurance demand under ambiguity, we derive theoretical predictions about the impact of several governmental assistance programmes on optimal insurance demand. For example, governmental assistance through a fixed public support scheme implies that partial insurance is always optimal under fair insurance with ambiguity. S…Read more
