A six-item scale measuring the degree to which a consumer perceives a brand or firm as exploiting its customer base — taking advantage of customers, treating them disrespectfully, and causing them harm through its business practices. One item is reverse-scored. Developed in research on market power and price fairness, the scale captures the moral dimension of brand power perception — specifically the extent to which consumers view the firm's behaviour as ethically violating the consumer relationship.
