This study examines the effects of an organization's power exercises on managing relations with their consumers. A telephone survey of 368 citizens aged above 20 years and living in five major cities in Taiwan was conducted to collect data about their perceptions of public and private companies or firms with which they had any kind of relationship. The results indicated that organizations that interacted with targeted publics used information power, legitimate power, reward power, and coercive power. Only information power, reward power, and coercive power affected the outcomes of relationships with the respondents in this study. The results indicated that the use of information power caused greater and more positive influences than the use of reward power on relationship outcomes, and the use of coercive power negatively affected relationship outcomes.
