We consider a situation in which a group of banks consider connecting their Automated Teller Machines (ATMs) in a network, so that the banksâ€™ customers may use ATMs of any bank in the network. The problem studied is that of allocating the total transaction costs arising in the network, among the participating banks. The situation is modeled as a cooperativeâ€¦ (More)

This paper discusses the core of the game corresponding to the standard fixed tree problem. We introduce the concept of a weighted constrained egalitarian solution. The core of the standard fixed tree game equals the set of all weighted constrained egalitarian solutions. The notion of home-down allocation is developed to create further insight in the localâ€¦ (More)

This paper extends the notion of cost sharing to models with general demand aggregation rules. In the process, aggregated serial cost sharing mechanisms are defined and characterized. A framework for a dynamic view on cost sharing is provided, introducing the notion of consistency to the generalized cost sharing model. Corresponding optimistic andâ€¦ (More)
