Alliance with fintech: Are banks opening the Pandor box?
No full textInternational audienceThe emergence of fintech companies has disrupted the financial landscape, challenging the dominance of traditional banks. Fintech firms aim to compete by providing intuitive, simple, and efficient applications that prioritize customer experience. This article explores the competition dynamic between fintech and banks, highlighting the dual nature of fintech as both a threat and an opportunity for banks and the strategic approaches taken by them to collaborate, acquire or compete head-on with fintech start-ups. The profitable alliance between banks and fintech is also discussed, emphasizing the strategic collaborations that drive innovation in the industry
Spillover effects of competition outcome on future risky cooperation
No full textInternational audienceThere is growing evidence that risky cooperation is regulated by the experience of previous interactions with others. However, it is unclear how the evaluation of outcomes from competitive interactions can affect individuals’ subsequent cooperative behavior. To address this issue, we examined how participants cooperated with a partner having just competed with them. While competing, participants (N = 164) were randomly assigned to receive one of four types of outcome feedback regarding their performance (victory vs. defeat vs. uncertain vs. no competition (control)). We found that both the experience of defeats and of uncertainty as competitive outcomes exerted a negative impact on the extent to which participants then engaged in cooperative behavior with their recent opponents. This only occurred when such subsequent cooperative behavior involved a high potential for incurring personal costs but not when there was no risk of incurring personal costs and a positive return. Finally, mediation analysis revealed that the effect of defeat was mediated by participants’ level of interpersonal trust and the extent to which participants were willing to cooperate, while the effect of the uncertain competitive outcome was mediated only by the extent to which participants were willing to cooperate. These findings offer novel insights into how risky cooperation is modulated by previous competition
Essais sur la prise de décision en environnement incertain
No full textThis thesis studies beliefs, ambiguity attitudes, and dynamics of attention and their role on decision-making processes in economic contexts. Chapter 1 proposes a new method to measure beliefs and ambiguity attitudes (determined by beliefs transformation) towards different sources of uncertainty. This method is implemented experimentally to equal and different sources and contexts of uncertainty. Findings support that, in face of equal sources of uncertainty, beliefs on events are context-independent, but the transformation of beliefs is context-dependent. To further understand ambiguity attitudes, Chapter 2 studies higher order ambiguity attitudes by comparing changes in higher order ambiguity attitudes when ambiguity is presented on the good versus the bad state of nature. Results shed light on which existing economic theories are more in line with particular ambiguous situations and the direction in which decisions vary according to how ambiguity is communicated. Finally, Chapter 3 investigates trading decisions in asset markets and their underlying cognitive mechanisms represented in sampling information (analyzed through eye-tracking). Findings reveal that behavioral trading patterns are not alwayscoherent with their expected dynamics of attention.Cette thèse étudie les croyances, les attitudes face à l’ambiguïté et la dynamique de l’attention dans les processus de prise de décision dans des contextes économiques. Le chapitre 1 propose une nouvelle méthode pour mesurer les croyances et les attitudes face à l’ambiguïté (déterminées par la transformation des croyances) à l’égard de différentes sources d’incertitude. Cette méthode est appliquée expérimentalement à des sources et contextes d’incertitude égaux et différents. Les résultats confirment que, face à des sources d’incertitude égales, les croyances sur les événements sont indépendantes du contexte, mais que la transformation des croyances dépend du contexte. Pour mieux comprendre les attitudes face à l’ambiguïté, le chapitre 2 étudie les attitudes face à l’ambiguïté d’ordre supérieur en comparant les changements d’attitudes face à l’ambiguïté d’ordre supérieur lorsque l’ambiguïté est présentée sur le bon ou le mauvais état de la nature. Les résultats identifient les théories économiques existantes qui correspondent le mieux à des situations ambiguës particulières, et la direction dans laquelle les décisions varient en fonction de la manière dont l’ambiguïté est communiquée. Enfin, le chapitre 3 étudie les décisions de négociation sur les marchés d’actifs et leurs mécanismes cognitifs sous-jacents représentés dans les processus d’échantillonnage de l’information (analysées par eye-tracking). Les résultats révèlent que les modèles comportementaux de décision financière ne sont pas toujours cohérents avec la dynamique de l’attention attendue
Hazardous waste transportation: a cost allocation analysis
No full textThis paper studies hazardous waste transportation problems. Due to their dangerous nature, the transportation of these waste implies a risk of incident having irreversible consequences on the environment. This problem has lead to a body of legal statutes that monitor the generation, storage and transportation of hazardous waste. Assuming that the transport of hazardous waste is done in a cooperative manner on a transport network, this paper investigates how to share the cost of maintaining and operating such network among the involved agents. We analyze the hazardous transportation problem from the viewpoint of axiomatic analysis. We consider several axioms that are derived from different environmental law principles and provide a characterization of a new allocation rule: the responsibility rule. Then we show that the responsibility rule coincides with the multi-choice Shapley value of an appropriate multi-choice game
COVID-19 and Mobility: Determinant or Consequence?
No full textThis paper disentangles the relationship between COVID-19 propagation and mobility. In a theoretical model allowing mobility to be endogenously determined by the COVID-19 prevalence rate, we show that an exogenous epidemic shock has an immediate effect on mobility whereas an exogenous mobility shock influences epidemic variables with a delay. In the long run, exogenous disease contagiousness and mobility jointly shape epidemiological outcomes. The short-run theoretical result allows us to recover, empirically, the causal impacts of mobility and COVID-19 hospitalisations on each other in France. We find that hospitalisations are highly sensitive to mobility whereas mobility is little influenced by hospitalisations. In France, it seems therefore that voluntary social distancing would not have been effective to control the epidemic, in the absence of social distancing mandates
Between Being and Becoming: Appearances and Subjectivities of Organizing
No full textInternational audienceAs a conclusion for this edited book, this chapter comes back to three issues: appearances in and beyond organizing, subjectivity and subjectivation, and the future of phenomenologies in Management and Organization Studies (MOS). Potentials for expanding and decentering MOS concepts with and through phenomenological perspectives are discussed in regard to process philosophy, pragmatism, and critical theory. We argue that managerial and organizational phenomenologies and post-phenomenologies could go beyond a unilateral relationship with philosophy as a field. They could become the new ontological or metaphysical ground of organizing. The chapter is an opportunity both to summarize what are seen as key lessons of the experience of this book and to direct our gaze towards such potential avenues for discussion
Applications of Computational Intelligence in Management & Mathematics : 8th ICCM, Nirjuli, AP, India, July 29–30, 2022
No full textInternational audienceComputational intelligence consists of those techniques that imitate the human brain and nature to adopt the decision-making approach. This book contains selected papers from the 8th International Conference on Computers, Management and Mathematical Sciences (ICCM) 2022 about fuzzy systems, neural networks and evolutionary computation that can address stochastic environments where reasoning is a significant attribute to derive potential solutions and focus on the business domain's computational aspects.This is a conference proceedings for scholars/students who are using the powerful algorithms, concepts and principles of computational intelligence in a wide spectrum of research cases.<br/
