26. Two necessary conditions for leaders to have the effects specified in proposition two are that leaders have the opportunity to communicate the collective vision to potential followers and that the role of followers be definable in ideological terms that appeal to them. This is a modification of one of the propositions originally advanced by House (1977).

27. The emergence and effectiveness of value based leaders will be facilitated to the extent to which a) performance goals cannot be easily specified and measured, b) extrinsic rewards cannot be made clearly contingent on individual performance, c) there are few situational cues, constraints and reinforcers to guide behavior and provide incentives for specific performance, and d) exceptional effort, behavior and sacrifices are required of both the leaders and followers. This proposition is based on the earlier discussion of strength of situations and dissonance theory and is a modest modification of one of the propositions originally advanced by Shamir et al. (1993).

The hypotheses were tested within the context of a latent structure casual model, using Partial Least Squares Analysis (PLS). This modelling procedure requires that substantive hypotheses be modelled in the form of paths connecting the hypothesized variables. The variables are latent constructs composed of scores on manifest indicators. The The slopes of these relationships are presented in Figure 3. This finding supports the competitive hypothesis 5a which states that LMP will have greater effects in non-entrepreneurial firms than in entrepreneurial firms, and will be discussed below.

IMPLICATIONS

In this section we first discuss the implications of the findings with respect to the value based leadership. Next we discuss the implications of the findings for each of the five theories that were integrated in the models tested. We then discuss the more general implications of the study for the discipline of Organizational Behavior.

Value Based Leadership

Thomas (1988), House et al. (1991), and by Waldman, Ramirez and House (1996)

demonstrate longitudinally, and with adequate controls for spurious relationships, that leaders have substantial effects on the performance of the organizations they manage. However, there have been no studies, other than the U.S. presidential study (House et al., 1991), that investigate the leader motives and behavior that lead to such leader effects. Thus there has been a "black box" concerning how leader processes influence overall organizational performance that remains to be explained.

Collectively, the findings of the present study help to understand the phenomena in the "black box." More specifically, the findings show, in some detail, important relationships between chief executives' motives and behavior and subordinates' motivation and commitment to their organization. Having shown how the components function, it  is now possible to test linkages between leader behavior, subordinate responses, and organizational effectiveness using longitudinal quasi experimental designs.

Implications for Specific Theories

In this section we discuss the implications of the study findings for each of the theories that are integrated to form the Value Based Theory of Leadership.

Achievement Motivation Theory

Achievement motivation has a more positive effect on CEMS and all leader behaviors in entrepreneurial firms than in non-entrepreneurial firms. This finding constitutes yet another confirmation of achievement motivation theory concerning the specific conditions under which achievement motivation is predicted to result in high performance.

Moral Responsibility Theory

The bivariate relationships between the moral responsibility disposition and value based leader behavior, leader fairness and CEMS, and the moderating effect of responsibility on the relationships between the power motive, and CEMS, leader charisma, and support/reward behavior all provide support for Moral Responsibility Theory. Moral responsibility motivation is clearly an important disposition that deserves further investigation and attention.
