Abstract

The objective of this study was to evaluate the chances of commitment in group decision making process, modeled by a multicriteria method based on game theory and its evaluation in relation to the satisfaction and sense of justice of the players. We hypothesized that mathematical methods may favor group decision-making, reflecting higher levels of sense of justice and satisfaction and consequently greater chances of commitment to the agreements made. By means of 75 simulations, with five volunteers each, the hypotheses of this study were confirmed, which include the affirmation that the commitment in group decision making can be increased by the use of a method to support group decision making and, consequently, that the sense of justice and satisfaction will be greater when agreements are supported by some sort of mathematical method.

Highlights

Group decision-making requires a structured process (Keeney, 1982; Bazerman & Moore, 2012), and the implementation of the decision, since the commitment to a group decision can be broken whether individuals are not satisfied with the agreement (Harsanyi, 1977) or do not perceive justice in the decision-making process (Rawls, 1971)
The objective of this study is to evaluate how the commitment to agreements can be improved by the application of a group multicriteria method based on game theory and the analysis of the satisfaction and the sense of justice of the agents
A group multicriteria decision making method would hardly prescribe the final result of a negotiation process, as it was noticed in this research with around 41% of accuracy in predicting the outcome of the negotiation, it was observed that when commitment occurred and the method matched the negotiated solution, which corresponded to 54% of the time in this research, the highest levels of satisfaction and sense of justice were reported

Summary

Introduction

Group decision-making requires a structured process (Keeney, 1982; Bazerman & Moore, 2012), and the implementation of the decision, since the commitment to a group decision can be broken whether individuals are not satisfied with the agreement (Harsanyi, 1977) or do not perceive justice in the decision-making process (Rawls, 1971). The perception of justice is an important antecedent of commitment to the implementation of agreements, known as contracts (Filenga & Siqueira, 2006; Li & Cropanzano, 2009; Mislin et al, 2011; Cropanzano et al, 2015; Park et al, 2016; Druckman & Wagner, 2017; Saha & Kumar, 2017). When an individual perceives that is not benefited by a solution proposed in an agreement reached by the group, and that, on the contrary, the breach of contract is what would bring him/her most benefits, it is expected that the individual does not honor the contract (Li & Cropanzano, 2009; Camerer, 2011). Moore (2007) states that the unbalanced payoffs of members of a decision group is a good indicator for breach of contract, which is the case even when an individual choose to reduce the maximization of its own gains (Charness & Sutter, 2012; Camerer, 2011). When there is evidence that the decision will not be maintained, lower levels of satisfaction and sense of justice can be noticed (Filenga and Siqueira 2006)
