Equilibrium in Queues Under Unknown Service Rates and Service Value

We study a single queue joining equilibrium when there is uncertainty in the consumers' minds about the service rate and value. Without such uncertainty, the joining equilibria are characterized by means of a single threshold queue length above which consumers do not join (Naor, 1969) . We show that in the presence of such uncertainty, the equilibrium joining strategy is not fully characterized by a single threshold. A "sputtering equilibrium" might exist. In the sputtering equilibrium, the
