In this paper we study hedonic games where each player views every other player either as a friend or as an enemy. Two simple priority criteria for comparison of coalitions are suggested, and the corresponding preference restrictions based on appreciation of friends and aversion to enemies are...

Top responsiveness is a concept which provides a model of progressive society in wihch each player pays more attention to the best aspect of each coalition, and is shown to be a sufficient conditaion for the existence of core stable coalition structures. In this paper, we propose a new concept,...

We investigate the computational complexity of several decision problems in hedonic coalition formation games and demonstrate that attaining stability in such games remains NP-hard even when they are additive. Precisely, we prove that when either core stability or strict core stability is under...

This paper considers a model of economic network characterized by an endogenous architecture and frictions in the relations among agents as described in Bala and Goyal (2000). We propose a similar network model with the difference that frictions in the relations among agents are endogenous....

We study the stability of social and economic networks when players are farsighted. In particular, we examine whether the networks formed by farsighted players are different from those formed by myopic players. We adopt Herings, Mauleon and Vannetelbosch's (Games and Economic Behavior,...

Instead of taking the orthodox view of business corporations as nexuses of contracts as a basic premise, this article focuses on their aspect as “incorporating” autonomous systems of associational (group-level) cognition for business objectives. In order for such a system to be consistent...

Pongou and Tondji (Pongou and Tondji, Games and Economic Behavior, 108, 206-224, 2018) described an uncertain production environment as a situation where input supply is uncertain. Each input has a finite set of actions, and uncertainty is formalized as a probability distribution over this set....

Aguiar et al. (2018) propose the Shapley distance as a measure of the extent to which output sharing among the stakeholders of an organization can be considered unfair. It measures the distance between an arbitrary pay profile and the Shapley pay profile under a given technology, the latter...
