This paper explores the extent to which bargaining power asymmetries among supply chain members moderate the effect that the delay costs of the setting exert on negotiation outcomes. First, we propose that the influence of delay costs on the initial gap between the bargaining demands of sellers and buyers (i.e., initial bargaining gap) decreases when buyers have a bargaining power advantage over sellers. Second, we posit that this moderation effect reduces the indirect effect that the delay costs have on negotiation outcomes (via the initial bargaining gap). To test these notions, we conduct a 2 × 2 between-subjects experiment with undergraduate students from a large European university in which we manipulate the relative bargaining power a...
