摘要: Very often in social life individuals take decisions within groups (households, friendships, trade unions, local jurisdictions, networks, etc.). The formation of coalition may imply some theoretical difficulties, such as costs arising from forming a or sharing information among agents. Coalition has the explicit purpose to represent process coalitions agents and hence modelling number relevant economic phenomena. Moreover, following this applied literature on coalitions, seminal chapter by Jackson Wolinsky (1996) opened way new stream contributions using networks (graphs) model links individuals. In we will assume that only subset \(\fancyscript{S}\) set all possible an economy is admissible coalitions. We define \(\fancyscript{S}\)-core concept, Herves-Moreno. extend with both uncertainty asymmetric informations results showed Okuda Shitovitz.
