Connections between Classical and Parametric Network Entropies

This paper explores relationships between classical and parametric measures of graph (or network) complexity. Classical measures are based on vertex decompositions induced by equivalence relations. Parametric measures, on the other hand, are constructed by using information functions to assign probabilities to the vertices. The inequalities established in this paper relating classical and parametric measures lay a foundation for systematic classification of entropy-based measures of graph complexity

Offer and veto: an experimental comparison of two negotiation procedures

Negotiation by veto is introduced as a novel negotiation approach and as an alternative to the exchange of offers. Rather than proposing offers, negotiators following the negotiation by veto approach eliminate unfavorable settlement options from the set of possible agreements until they eventually achieve a mutual acceptable solution. It is argued that this approach could lead to superior negotiation outcomes and improve negotiators’ satisfaction. In an experiment with student participants the performance of offer and veto negotiation procedures is compared. In simple negotiation problems both negotiation procedures reach similar outcomes. In complex negotiation problems negotiation by veto achieves fewer but better agreements. However, participants were more satisfied with the negotiation process, outcome and their opponent’s behavior when exchanging offers rather than vetoing alternatives.83991
