It also diregards social institutions whose rules are not (and are not meant to be) in equilibrium. Finally, his suggestion that institutional equilibria necessarily involve correlation devices appers to lack justification %K Guala %K institutions %K social institution %K rules %K equilibria %K correlated equilibrium %K Searle %K Lewis %K Aumann %U https://journals.sagepub.com/doi/full/10.1177/0048393118798643
