The behaviour of solutions to bargaining problems on the basis of solidarity

Abstract

The main purpose of this paper is to provide a systematic study of the solidarity-type axioms for classical convex bargaining problems. As a consequence, we present alternative characterizations for some well-known solutions in the literature. Instead of using the Monotonicity axiom, the paper provides characterizations of the egalitarian solution and the Kalai-Somorodinsky solution using slightly weaker versions of Nash's original IIA for convex bargaining problems with a fixed population. © Journal compilation © 2008 Japanese Economic Association.
