On the Role of Non-equilibrium Focal Points as Coordination Devices Antoni Bosch-Domènech, Universitat Pompeu Fabra and CREA, Barcelona Nicolaas J. Vriend, Queen Mary, University of London Department of Economics Working Paper No. 621, Queen Mary, University of London, 2008 [Also appeared as: Universitat Pompeu Fabra (Barcelona), Dept. of Economics and Business Working Paper 1064] Abstract.
Considering a pure coordination game with a large number of equivalent equilibria,
we argue, first, that a focal point that is itself not a Nash equilibrium and is
Pareto dominated by all Nash equilibria, may attract the players' choices. Second,
we argue that such a non-equilibrium focal point may act as an equilibrium selection
device that the players use to coordinate on a closely related small subset of Nash
equilibria. We present theoretical as well as experimental support for these two new
roles of focal points as coordination devices. Nick Vriend, n.vriend@qmul.ac.uk Last modified 2009-06-13 |
