Influence is a fundamental element of negotiation, nor that do both parties tend to want and seek influence over the counterpart in negotiation. This chapter will focus on two primary sources of influence: power and status. Power is a source of influence from objective, structural sources such as possession of resources or position in networks of relationships; status is a source of influence stemming from others’ consensual judgment. Though power has the focus of work on influence in negotiation, both are important and both are considered here.
