This specification of value based leader behaviors integrates the behaviors specified in prior extensions of the 1976 theory of charismatic leadershipas well as behaviors specified in other theories of charismatic, transformational and visionary leadership. House and Shamir (1993) provide the rationale for inclusion of the above behaviors in the theoretical leader behavior syndrome.

Axioms

Axioms are statements, the validity of which are taken for granted, either because the enjoy substantial empirical evidence or becuse they cannot be tested. Axiomsprovide a foundation for more specific statements, such as propositions. The axioms stated here provide the foundation for the selection of leader behaviors from among all of the leader behaviors specified in the various theories described above.

Axioms Concerning Human Motivation

1. Humans tend to be not only pragmatic and goal-oriented, but are also self-expressive. It is assumed that behavior is not only instrumental-calculative, but also expressive of feelings, aesthetic values and self-concepts. We \"do\" things because of who we \"are,\" because by doing them we establish and affirm an identity for ourselves, at times even when our behavior does not serve our materialistic or pragmatic self-interests.

2. People are motivated to maintain and enhance their generalized self-efficacy and self-worth. Generalized self-efficacy is based on a sense of competence, power, or ability to cope with and control one\'s environment. Self-worth is based on a sense of virtue and moral worth and is grounded in norms and values concerning conduct.

3. People are also motivated to retain and increase their sense of self-consistency. Self-consistency refers to correspondence among components of the self-concept at a given time, to continuity of the self-concept over time, and to correspondence between the self-concept and behavior. People derive a sense of \"meaning\" from continuity between the past, the present and the projected future, and from the correspondence between their behavior and self-concept.

4. Self-concepts are composed of values, perceptions of self-worth, efficacy, and consistency, and also identities. Identities, sometimes referred to as role-identities, link the self-concept to society. Social identities locate the self in socially recognizable categories such as nations, organizations and occupations, thus enabling people to derive meaning from being linked to social collectives.

5. Humans can be strongly motivated by faith. When goals cannot be clearly specified or the subjective probabilities of accomplishment and rewards are not high, people may be motivated by faith because being hopeful in the sense of having faith in a better future is an intrinsically satisfying condition.

6. When individual motives are aroused in the interest of the collective effort, and when individual identify with the values inherent in the collective vision, they will evaluate themselves on the basis of the degree to which they contribute to the collective effort. Under conditions of motive arousal and value identiication individuals experience intrinsic satisfaction from their contribution to the collective effort and intrinsic dissatisfaction from failure to contribute to collective efforts.

These axioms incorporate the extensions of the 1976 theory of charismatic leadership offered by Shamir, House and Arthur (1993), and House and Shamir (1995) and provide the integrative framework for the Value Based Theory of Leadership.

PROPOSITIONS

The theory is expressed in the form of twenty-seven propositions which assert specific ways in which leader motives and behaviors, in conjunction with situational variables, affect follower motivation and performance and organizational performance. These propositions are based on the leadership and psychological theories reviewed above and reflect the extensions of the 1976 Theory of Charismatic Leadership contributed by House et al. (1991), Shamir et al. (1993), House and Shamir (1993), and Waldman, Ramirez and House (1996).

Propositions Concerning Leader Behavior and Its Effects

1. The motivational effects of the behaviors of the value based leader behavior

syndrome described above will be heightened follower recognition of shared values between leaders and followers, heightened arousal of follower motives, heightened follower self-confidence, generalized self-efficacy and self-worth, strong follower self-engagement in the pursuit of the collective vision and in contributing to the collective, and strong follower identification with the collective and the collective vision. We refer to these psychological reactions of followers as the value based motive syndrome .

2. The behavioral effects of the value based motive syndrome will be heightened commitment to the collective as manifested by follower willingness to exert effort above and beyond normal position or role requirements, follower self-sacrifice in the interest of the vision and the collective, and increased collective social cohesion and organizational collaboration. We refer to these effects as the value based follower commitment syndrome. While the value based motive syndrome described in proposition one is not directly observable, the behaviors of the value based follower commitment syndrome are.

Propositions Concerning Leader Attributes

3. Self-confidence and a strong conviction in the moral correctness of one\'s beliefs will be predictive of proactive leadership. This proposition is a slight modification of proposition three of the 1976 Theory of Charismatic Leadership. This proposition has been supported by Smith (1982), House et al. (1991), and Howell and Higgins (1991).

4. Strong leader concern for the morally responsible exercise of power will be predictive of constructive, collectively oriented exercise of social influence by leaders and predictive of the value based motive and follower commitment syndromes specified in propositions 1 and 2 above.

5. Power motivation coupled with a strong concern for the morally responsible exercise of power will be predictive of the constructive, collective-oriented exercise of social influence by leaders.

6. Power motivation, unconstrained by a strong concern for the moral exercise of power, will be predictive of impetuously aggressive and self-aggrandizing exercise of social influence.
