Decision-making on real-world problems, including individual process decisions, requires an appropriate and reliable decision support system. Fuzzy set theory, rough set theory, and neutrosophic set theory, which are MCDM techniques, are useful for modeling complex decision-making problems with...

The importance of correct and clear decisions during a complex and difficult situation is very easy to understand, but not so easy to achieve. Especially in situations where decision-makers must decide under time pressure and uncertainty. For instance, typical crisis situations have such...

We study the choice of a principal to either delegate a decision to a group of careerist experts, or to consult them individually and keep the decision-making power. Our model predicts a trade-off between information acquisition and information aggregation. On the one hand, the expected benefit...

We study cheating as a collective-risk social dilemma in a group setting in which individuals are asked to report their actual outcomes. Misreporting their outcomes increases the individual's earnings but when the sum of claims in the group reaches a certain threshold, a risk of collective...

Purpose - In the presence of coronavirus disease 2019 (COVID-19), due to the social distance restriction, consumers' regular consumption behaviors and patterns have been changing fundamentally. Thereafter, an innovative group buying model has emerged and developed explosively with a specific...

Considering the environment of risks and influences inherent in the decision-making process for credit-granting operations, it has become a matter of survival for financial organizations to seek to improve how they engage in effective decision-making to ensure that their returns on invested...

Team-managed mutual funds exhibit a disposition effect: they are reluctant to sell losers relative to winners. This propensity is costly as winners sold outperform losers held by 56bp during the next quarter relative to stocks with similar size, book-to-market, and momentum characteristics....

What determines whether someone complies with a social norm? The social identity approach offers a mechanism for norm compliance: a person who feels similar to a group identifies more with that group and, in turn, complies with the group's norms. We used an economics experiment to test this...

Even in school districts with relatively permissive approaches to defining and embodying gender, the identities of transgender and gender variant students are often governed by complex regulatory protocols. Ensuring that a student is able to live their gender at school can involve input from a...

We introduce "group cohesion" to study the economic relevance of social relationships in team production. We operationalize measurement of group cohesion, adapting the "oneness scale" from psychology. A series of experiments, including a pre-registered replication, reveals strong positive...

I develop a model of (individually rational) collective reality denial in groups, organizations and markets. Whether participants' tendencies toward wishful thinking reinforce or dampen each other is shown to hinge on a simple and novel mechanism. When an agent can expect to benefit from other's...

A correct aggregation of stakeholders’ preferences is a vital aspect in solving problems associated with natural resources. In fact, there is no one solution that permits the incorporation of those preferences into techniques that, in turn, may address multiple objectives in the management of...

Green and sustainable engineering business models have become a major topic across industries due to concerns regarding environmental issues and the decline of natural resources. Remanufacturing is showing promise as a preferable solution in terms of environmental, societal, and economic factors...

This paper studies experimentally when and how ideological motives shape outcomes in group decision-making scenarios. Groups play a repeated coordination game in which they can agree on a payoff-dominant or a payoff-dominated but ideologically preferred outcome, or disagree and forego all...

Fair Assignment of Debt Cases to Legal Debt Collection Centers -- On the Principle of Lagrange in Optimization Theory and Its Application in Transportation and Location Problems -- Measuring Foreign Trade-Logistics Efficiency: A DEA Approach and the Malmquist Index -- Partially Non-discretionary...

Despite advances in the field, we still know little about the socio-cognitive processes of team decisions, particularly their emergence from an individual level and transition to a team level. This study investigates team decision processes by using an agent-based model to conceptualize team...

Many important intertemporal decisions are made by groups rather than individuals. What happens to collective decisions when there is internal conflict about the tradeoff between present and future has not been thoroughly investigated so far. We study experimentally the causal effect of group...
