Leader–member exchange theory

Leader–member exchange (LMX) theory addresses a specific aspect of the leadership process, which evolved from an earlier theory called the vertical dyad linkage model. Both of these models focus on the interaction between leaders and individual followers. Similar to the transactional approach, this interaction is viewed as a fair exchange whereby the leader provides certain benefits such as task guidance, advice, support, and/or significant rewards and the followers reciprocate by giving the leader respect, cooperation, commitment to the task and good performance. However, LMX recognizes that leaders and individual followers will vary in the type of exchange that develops between them. LMX theorizes that the type of exchanges between the leader and specific followers can lead to the creation of in-groups and out-groups. In-group members are said to have high-quality exchanges with the leader, while out-group members have low-quality exchanges with the leader.
