Limitations in the equity-theory approach: Toward a Resolution of the "negative-inputs" controversy
Recent exchanges in the Bulletin have attempted to resolve difficulties in the possibility of negative inputs in the defini tions of equity "formulae". The present discussion suggests that the difficulties can be resolved if the range of application of equity formulations is restricted to relationships in which members' out comes add up to a fixed value. Differences between this condition and those generally existing in relationships are discussed with particular reference to Thibaut and Kelley's theory of interpersonal exchange.
