Is Having a Unique Equilibrium Robust?
We investigate whether having a unique equilibrium (or a given number of equilibria) is robust to perturbation of the payoffs, both for Nash equilibrium and correlated equilibrium. We show that the set of n-player finite games with a unique correlated equilibrium is open, while this is not true of Nash equilibrium for n > 2. The crucial lemma is that a unique correlated equilibrium is a quasi-s...

متن کاملHaving a Plan B for Robust Optimization
We extend the standard concept of robust optimization by the introduction of an alternative solution. In contrast to the classic concept, one is allowed to chose two solutions from which the best can be picked after the uncertain scenario has been revealed. We focus in this paper on the resulting robust problem for combinatorial problems with bounded uncertainty sets. We present a reformulation...
متن کاملUnique and Optimal Perfect Equilibrium
This paper proves a First Welfare Theorem for Games it shows that asynchronous dynamic games with voluntary one period ahead transfers have a unique optimal equilibrium. The equilibrium coincides with the Utilitarian Pareto Optimum and hence can be computed from a (simpler) programming problem (rather than as a fixed point). Whilst it is commonly thought that Folk Theorems are endemic in dynami...
