Erlang Fixed-Point (EFP) approximation, which is based on an independent blocking assumption, has been used for networks both … with and without controls. Several more elaborate approximation methods which account for dependencies in blocking …

strand of recent literature on the implications of market microstructure for asset pricing, this paper suggests that …

notion of an interval core has been coined and proposed as a solution concept for interval-valued games. In this paper we … will present a general mathematical programming algorithm which can be applied to find an element in the interval core. As … demonstrate how interval core elements can be computed. Also, we reveal that pitfalls exist if interval core elements are computed …

coalition production economy corresponding to the game. First, it is shown that the full core of a TU game is not empty if and … only if the completion of the game is balanced. The full core is defined free of any particular coalition structure and the … coalitions of the game emerge endogenously from the full core. Second, it is shown that the full core of a completion …

We are concerned with the problem of core membership testing for hedonic coalition formation games, which is to decide … whether a certain coalition structure belongs to the core of a given game. We show that this problem is co-NP complete when …

the clan by a "dualize and extend" procedure. These procedures are also useful for relating core elements and elements of …
