An Extension of the Solidarity Value for Environments with Externalities Article uri icon


  • In this paper, we propose an axiomatic extension for the Solidarity value of Nowak and Radzik [1994] A solidarity value for n-person transferable utility games, Int. J. Game Theor. 23, 43-48] to the class of games with externalities. This value is characterized as the unique function that satisfies linearity, symmetry, efficiency and average nullity. In this context, we discuss a key subject of how to extend the concept of average marginal contribution to settings where externalities are present. © 2017 World Scientific Publishing Company.
