On the Felsenthal Power Index

Abstract The paper that introduces the Felsenthal index is titled: ‘A well-behaved of a priori P -Power for simple n-person games.’ In 2016, introduced his games. His definition does not base on axiomatic approach. Then, regarded some properties and proved satisfies list six reasonable compelling postulates. Three he refer to weighted games, but this fact reduce He proves none seven well-known efficient power indices proposed date postulates, indicating each them which postulates violate. we extend originally defined main objective article answer three open questions motivated in article. particular, prove may be unique one fulfilling provide an characterization and, propose impossibility result, obtained by adding new postulate sublist considered. We also remark existence alternative are satisfied index.
