We prove uniqueness of stationary equilibria in a one-dimensional model of bargaining with quadratic utilities, for an arbitrary common discount factor. For general concave utilities, we prove existence and uniqueness of a "minimal" stationary equilibrium and of a "maximal" stationary equilibrium. We provide an example of multiple stationary equilibria with concave (nonquadratic) utilities. (C) 2003 Elsevier Inc. All rights reserved.
