Economic rationality and ethical behavior

This paper argues that economic rationality and ethical behavior cannot be reduced one to the other, casting doubts on the validity of formulas like 'profit is ethical' or 'ethics pays'. In order to express ethical dilemmas as opposing economic interest with ethical concerns, we propose a model of rational behavior that combines these two irreducible dimensions in an open but not arbitrary manner. Behaviors that are neither ethical nor profitable are considered irrational (non-arbitrariness). However, behaviors that are profitable but unethical, and behaviors that are ethical but not profitable, are all treated as rational (openness). Combining ethical concerns with economic interest, ethical business is in turn an optimal form of rationality between venality and sacrifice. Because every one prefers to communicate that he acts ethically, ethical business remains ambiguous until some economic interest is actually sacrificed. We argue however that ethical business has an interest in demonstrating its consistency between communication and behavior by a transparent attitude. On the other hand, venal behaviors must remain confidential to hide the corresponding lack of consistency. This discursive approach based on transparency and confidentiality helps to further distinguish between ethical and unethical business behaviors.Rationality, business ethics, economic rationality, transparency, confidentiality

A process approach to the utility for gambling

This paper argues that any specific utility or disutility for gambling must be excluded from expected utility because such a theory is consequential while a pleasure or displeasure for gambling is a matter of process, not of consequences. A (dis)utility for gambling is modeled as a process utility which monotonically combines with expected utility restricted to consequences. This allows for a process (dis)utility for gambling to be revealed. As an illustration, the model shows how empirical observations in the Allais paradox can reveal a process disutility of gambling. A more general model of rational behavior combining processes and consequences is then proposed and discussed.Gambling, expected utility, process utility, rationality, irrationality, consequentialism

The biased balance: Observation, formalism and interpretation of a dissymmetric measuring device

This paper studies a balance whose unobservable fulcrum is not necessarily located at the middle of its two pans. It presents three different models, showing how this lack of symmetry modifies the observation, the formalism and the interpretation of such a biased measuring device. It argues that the biased balance can be an interesting source of inspiration for broadening the representational theory of measurement.Representational theory of measurement, biased measurement, bias, rationality, irrationality, observer, dependence, indeterminacy, invariance

Improving speaker turn embedding by crossmodal transfer learning from face embedding

Learning speaker turn embeddings has shown considerable improvement in situations where conventional speaker modeling approaches fail. However, this improvement is relatively limited when compared to the gain observed in face embedding learning, which has been proven very successful for face verification and clustering tasks. Assuming that face and voices from the same identities share some latent properties (like age, gender, ethnicity), we propose three transfer learning approaches to leverage the knowledge from the face domain (learned from thousands of images and identities) for tasks in the speaker domain. These approaches, namely target embedding transfer, relative distance transfer, and clustering structure transfer, utilize the structure of the source face embedding space at different granularities to regularize the target speaker turn embedding space as optimizing terms. Our methods are evaluated on two public broadcast corpora and yield promising advances over competitive baselines in verification and audio clustering tasks, especially when dealing with short speaker utterances. The analysis of the results also gives insight into characteristics of the embedding spaces and shows their potential applications

Acceleration of the retrieval of past experiences in Case Based Reasoning : application for preliminary design in Chemical Engineering

The way to manage knowledge accumulated is one of the firm’s trends, in order to capitalize and to transmit this knowledge. Some Artificial Intelligence methods are devoted to preserve and to reuse past experiences. Case Based Reasoning (CBR) is one of these methods dedicated to problem solving, new knowledge acquisition and knowledge management. CBR is a cyclic method where the central notion is a case which represents an earlier experience. Several cases are collected and stored in a memory: the case base. The goal of this paper is to soften the way to describe problem and to increase the effectiveness of the system during the retrieval of relevant case

The role of power for distributive fairness

We employ an experimental labour setting to study fairness in the division of gains from productive activity. The focus is on the impact of power structures on allocation decisions and on fairness perceptions. Two types of actors are involved in generating a gain, but only one contributes actively by completing a real-effort task. In three treatments, decision power to divide the gain is assigned (1) to the inactive, (2) jointly to the inactive and the active, and (3) to the active. Results show that the impact of power goes beyond changing final allocations: it also significantly alters fairness perceptions. Decision power - in particular absolute power – mediates and significantly enhances self-serving biases. Results complement studies on the psychology of fairness perceptions. Moreover, the paper discusses implications for organizational design.
