We define a solution to the problem of coalition formation that applies to purely hedonic games. Coalition structures satisfying our requirements are called durable, and we interpret them as much more likely to last than those coalition structures not satisfying the requirements, which we call transient. Durability results from a combination of foresight and extreme risk aversion on the part of...

Scholars have long studied the conditions under which the cabinet making process will result in minority, surplus majority, or minimum-winning governing coalitions in parliamentary systems. Since Riker, a good number of these attempts have been based on rational choice assumptions. Among formal approaches in this vein, Laver and Shepsle’s (1996) portfolio allocation model argues that parties ce...

Dynamic coalition formations occur in response to some market demands, business requests, or disaster responses, to name a few.

This paper argues that Dynamic Coalition Peer-to-Peer (P2P) Network exists in numerous scenarios where mobile users cluster and form coalitions, and the relationship between sizes of coalitions and distances from mobile nodes to their Point of Interest (PoI) follows exponential distributions. The P2P coalition patterns of mobile users and their exponential distribution behavior can be utilized ...

Tarsal coalition is a congenital defect that results when adjacent tarsals fail to separate properly during embryonic development. Anatomically, coalitions present as non-osseous bridges of cartilage or fibrocartilage – and occasionally as osseous bridges – between two neighboring bones.

It has long been known that in economies with satiation, the set of competitive equilibria does not coincide with the limiting core of an economy. Competitive equilibria may fail to exist because satiated agents may choose their optimal consumption bundles in the interiors of their budget sets, creating a total budget excess. On the other hand, the core of the economy grows very large. Satiated...
