Bargaining Effects of the Mandatory-Permissive Distinction

This study uses a laboratory experiment to examine empirically the effect of the mandatory permissive distinction on the negotiation of wages, employment guarantees, and advertising expenditures. Results suggest that negotiators spend more time bargaining over a smaller settlement range when an issue is mandatory than when it is permissive. Further, tentative findings provide no evidence that negotiators can circumvent the distinction through the use of tradeoffs across issues or bargaining power.
