Waiver, Effectivity and Rights as Game Forms.

This paper introduces the concept of a waiver function of a game form: a function that measures the extent to which one can leave choice to others. This is compared with the concept of effectively function used to measure the power of coalitions within a game form. The author shows that under some circumstances either function can be used to capture the notion of rights underlying game forms.
