  abstract     = {{The phenomenon that groups or people work together when they face an opponent,
although they have little in common otherwise, has been termed the "common enemy
effect". We study a model of network formation, where players can use links to build
a network, knowing that they are facing a common enemy who can disrupt the links
within the network, and whose goal it is to minimize the sum of the benefits of the
network. We find that introducing a common enemy can lead to the formation of
stable and efficient networks as well as fragmented networks and the empty network.}},

  abstract     = {{In this paper we introduce the concept of an overall power function that is meant
to combine two sources of a party’s power in a parliament. The first source is based
on the possibilities for the party to be part of a majority coalition and it is typically
modeled using a cooperative simple game. The second source takes into account
parties’ asymmetries outside the cooperative game and it is displayed by a vector
of exogenously given weights. We adopt a normative point of view and provide an
axiomatic characterization of a specific overall power function, in which the weights
enter in a proportional fashion.}},
