Catastrophe Aversion and Risk Equity in an Interdependent World
No full textCatastrophe aversion and risk equity are important concepts both in risk management theory and practice. Keeney [Keeney RL (1980) Equity and public risk. Oper. Res. 28(3):527–534] was the first to formally define these concepts. He demonstrated that the two concepts are always in conflict. Yet his result is based on the assumption that individual risks are independent. It has therefore limited relevance for real-world catastrophic events. We extend Keeney’s result to dependent risks and derive the conditions under which more equity and more correlation between two risks imply a more catastrophic situation. We then generalize some of the results for multiple correlated risks
Personality and risk aversion
No full textInternational audienceA number of papers have recently explored the relation between personality measures and risk aversion. However, research on risk aversion using the Myers-Briggs Type Indicator (MBTI) personality measure is scarce. The relation of various dimensions of the MBTI with risk aversion is at the moment under-researched compared to its use in the business and counseling world. To explore this relation, we carried out an incentivized experiment using 333 business school students. We find that according to our theoretical hypotheses, respondents scoring higher on Introversion, Sensing, Feeling and Judging are more risk averse, with the effect for Sensing and Feeling being non-linear. We also find women, Master students, respondents coming from a quantitative background and respondents that do not follow the stock markets to be more risk averse. The relations highlighted between the MBTI dimensions and risk aversion correspond broadly to the findings already evidenced using the Big 5 in studies using questionnaires or lotteries. This emphasizes the significant overlap between the two personality evaluation methods in relation to risk aversion. Our findings also underscore that the MBTI might be a useful tool in studies on risk aversion using lotteries, given the significant link of its dimensions with the elicited risk aversion in our study

Le réseau des affiliations de la communauté francophone des chercheurs en Systèmes d'Information
No full textInternational audienceCette étude analyse les articles de la revue Systèmes d'Information et Management et des communications au colloque de l'Association Information et Management, pour en comprendre le réseau des co-écritures d'articles. Une analyse du réseau des affiliations manquait encore à la compréhension des particularismes de la communauté francophone. Nous avons répondu à deux questions principales : quelle est la structure du réseau d'affiliations ? Qui sont les affiliations centrales ? Nous nous sommes intéressés aux caractéristiques du réseau en l'état, à chacun de bien vouloir contribuer à façonner sa communauté comme il souhaiterait qu'elle soit. Le thème du colloque de l'AIM 2018 « Rapprochons les communautés TI francophones » semble supposer que les communautés TI francophones soient distantes. Notre étude souhaite contribuer à ce rapprochement en montrant le réseau des affiliations des chercheurs et les distances qui séparent les différentes institutions entre elles
Perceived IT Ambiguity: Development of a Measurement Instrument
No full textInternational audienceInformation technologies (IT) have reached such degrees of functional richness that forming a complete, coherent, and stable understanding of a given IT product may be challenging for some users. The need to theorize this phenomena and to measure its effect on IT adoption empirically is rife. This paper introduces the construct of perceived IT ambiguity (PITA), which captures the extent to which a user has difficulties making sense of an IT artifact. A multi-item measurement scale is developed and its validity and reliability pre-tested on a pilot sample. The effect of the focal variable on technology adoption is tested using covariance-based SEM. Preliminary results indicate that ambiguity is a double-edged sword that simultaneously boosts and impede IT adoption
What can we learn from neurofinance ?
No full textInternational audienceNeurofinance is a relatively recent field which aims to unveil the neurobiologicalmechanisms through which decisions are made in finance. This article investigateshow neurosciences can contribute to the study of finance and the most appropriateways for neuroscientific methodologies to be applied to financial situations. In orderto examine these areas, we have produced a literature review around three axesof the main neuroscientific studies published in finance: financial risk; discountingand credit risk; information and trading decisions. One of the crucial insights offeredby neurofinance is how to reconcile classic and behavioral finance by showingthat emotions are critical to rational decision-making, in spite of also being part ofthe origin of biases. Through its unique set of techniques, neurofinance is able topinpoint the biological and neurological explanations behind some of the commonbiases highlighted by behavioral finance, as well as tackle some novel questions.We conclude this review by pointing toward potentially fruitful avenues for futureresearch and by highlighting which methods appear particularly well adapted forneurofinancial studies.La neurofinance est un champs de recherche relativement récent qui a pour objectif de dévoiler les mécanismes neurobiologiques par lesquels les décisions se prennent dans le domaine de la finance. Cet article analyse comme les neurosciences peuvent contribuer à étudier la finance et étudie les voies les mieux adaptées pour appliquer les methodologies neuro-scientifiques aux situations financières. Pour étudier ces questions, nous élaborons une synthèse de littérature autour de 3 axes: les risques financiers, le risque de crédit et l’actualisation et l’information et le trading. Une des contributions cruciales de la neurofinance est de réconcilier la finance classique et la finance comportementale en montrant que les émotions sont un frein à la prise de décision rationnelle. Grâce à son ensemble unique de techniques, la neurofinance est capable d’identifier les ressorts biologiques et neurologiques derrière les biais mis en évidence par la finance comportementale et de soulever de nouvelles questions. Nous parvenons à ouvrir de nouvelles voies de recherche fructueuses en mettant l’accent sur des méthodes qui semblent particulièrement adaptées pour les études en neurofinance
