The Serial Cost Sharing Rule has been conceived originally for problems where agents ask for different quantities of an homogeneous private good, the sum of which is produced by a single facility. Two important features of this rule is the equal treatment of equal demands and the protection it...

The traditional voting games are special transferable utility cooperative games, so-called simple games, where the players are the parties and the value of a coalition may be 1 or 0 depending on the ability of the coalition to pass a motion or not. In this paper we introduce general weighted...
