 More generally, Guala’s view seems to overstate the coordinating function of institutions and, as a result, conflate the underlying problem solved by an institution with the surface problem that the availability of multiple solutions gives rise to, i.e. the problem of coordinating on one of the available solutions. Thus the underlying problem of avoiding traffic collisions is solved by all traffic travelling in one direction keeping to one side of the road and all traffic travelling in the opposite direction keeping to the opposite side. However, this solution now gives rise to a coordination problem since there are two equally good solutions, i.e. all driving on the left or all driving on the right. This point applies to other rational choice coordination equilibria approaches, including Lewis’ influential theory of conventions (Miller 1986).
