Resumen:	We consider issue-externality games in which agents can cooperate on multiple issues and externalities are present both within and across issues, that is, the amount a coalition receives in one issue depends on how the players are organized on all the issues. Examples of such games are several Örms competing in multiple markets, and countries negotiating both a trade agreement (through, e. g. , WTO) and an environmental agreement (e. g. , Kyoto Protocol). We propose a way to extend (Shapley) values for partition function games to issue-externality games. We characterize our proposal through axioms that extend the Shapley axioms to our more general environment. The solution concept that we propose can be applied to many interesting games, including intertemporal situations where players meet sequentially.
