In an abstract model of division problems, we study division rules that are not manipulable through a reallocation of individual characteristic vectors within a coalition (e.g. reallocation of claims in bankruptcy problems). A coalition can be formed if members of the coalition are connected on...

We study allocation rules that are robust to coalitional manipulation by transferring, merging, or splitting individual characteristics among coalition partners (e.g. merging or splitting claims in bankruptcy problems). Coalition formation is restricted by an exogenous network (a non-directed...

We consider an abstract model of division problems where each agent is identi- fied by a characteristic vector. Agents are situated on a network (a non-directed graph) and any connected coalition can reallocate members¡¯ characteristics (e.g. reallocation of claims in bankruptcy problems). A...
