We develop a dynamic model in which a group collectively bargains with an external party. At each date the group makes an offer to the external party (the 'agent') in exchange for a concession. Group members hold heterogeneous preferences over agreements and are uncertain about the agent's...

Ever since Sen crystallized the logical conflict between the welfaristic value of the Pareto principle and the nonwelfaristic value of individual libertarian rights into what he christened the impossibility of a Paretian liberal , there have been many attempts in social choice theory to...

Many real-life applications of house allocation problems are dynamic. For example, in the case of on-campus housing for college students, each year freshmen apply to move in and graduating seniors leave. Each student stays on campus for a few years only. A student is a newcomer in the beginning...

Agents involved in a conflicting claims problem may be concerned with the proportion of their claims that is satisfied, or with the total amount they get. In order to relate both perspectives, we associate to each conflicting claims problem a bargaining-in-proportions set. Then, we obtain a...

A new feature pertaining to proposer's ability to implement offers is introduced in the extensive form bargaining mechanism studied in Chatterjee et. al. (1993). This mechanism is used to analyze two classes of coalitional games with transferable utility. One class is that of strictly...

Given a simple game, a power configuration specifies the power of each player in each winning coalition. We introduce a new power configuration which takes into account bargaining among players in coalitions. We show that under very weak conditions on a bargaining solution there is a power...

A common real-life problem is to fairly allocate a number of indivisible objects and a fixed amount of money among a group of agents. Fairness requires that each agent weakly prefers his consumption bundle to any other agent's bundle. In this context, fairness is incompatible with budget-balance...
