How can leaders influence follower performance by using principles based on identity theory?

Leaders can offer sizeable rewards to employees to increase their performance

Leaders can increase their subordinates' performance by helping them identify with their role in terms of their efficacy, values, and goals

Leaders cannot influence others' sense of identity, so the only thing they can do is to hire people who already have identities compatible with the job

Because leaders cannot influence others' identity, employees need to practice self$-$leadership to build their organizational identity
