Cooperative Equilibria and Conditional Obligations
Allard Tamminga, Barteld P. Kooi · 2009
We investigate group actions and their functioning in weak action obligations of the form “Group G of agents cannot do better than to perform action K” and in conditional weak action obligations of the form “If group H of agents performs action L, then group G of agents cannot do better than to perform action K”. Conditional weak action obligations are exactly what we need to express Nash-equilibria for n-player non-cooperative games. Moreover, our definition of Nash-equilibria in terms of conditional ob ligations can be generalized to obtain a solution concept for cooperative games.
