Purpose Drawing on the social exchange theory, the purpose of this paper is to examine the relationship between despotic leadership and employee’s organizational deviance. Specifically, the authors take a relational approach by introducing employee’s organizational identification as the mediator. The moderating role of value congruence in the relationship between despotic leadership and organizational deviance is also considered. Design/methodology/approach Data were collected from 15 universities in Turkey. The sample included 1,219 randomly chosen faculty members along with their department chairs. Hierarchical multiple regression analysis was conducted to test the proposed model. Findings The results of this study supported the positive effect of despotic leadership on employee’s organizational deviance as well as the mediating effect of employee’s organizational identification. Moreover, when the level of value congruence is high, the relationship between organizational identification and organizational deviance is strong, whereas the effect is weak when the level of value congruence is low. Practical implications The findings of this study suggest that educational administrators in the higher education should be sensitive in treating their subordinates, as it will lead to positive interpersonal relationship, which, in turn, will reduce organizational deviance. Moreover, they should pay more attention to the buffering role of value congruence for those subordinates with high distrust and showing organizational deviance.

Leader moral disengagement and follower knowledge hiding. A moderated mediation model of follower Machiavellianism and trust in the leader
(Emerald Publishing Limited, 2021-07-07) Erkutlu, H.; Chafra, Jamel
Purpose – This study aims to build a moderated mediation model to investigate the roles that trust in the leader and follower Machiavellianism can play in the relationship between moral disengagement of the leader and hiding of knowledge of the followers. Design/methodology/approach – Data were gathered from eight universities in Turkey using a set of 72 matched leader (dean)–follower (faculty member) questionnaires. The hypotheses were tested with multiple regression, moderated regression and bootstrapping analyses. Findings – The findings reveal that leader moral disengagement positively influences follower knowledge hiding, while trust in the leader mediates this influence and follower Machiavellianism not only moderates the relationship between leader moral disengagement and trust in the leader but also reduces the indirect relationship between leader moral disengagement and follower knowledge hiding through trust in the leader. Research limitations/implications –Even though measurements of research variables were collected from different sources and with time separation, common method bias might have existed. Also, this research is carried out in a single cultural context posing the issue of the generalizability of our findings to other cultural contexts. Originality/value – The main contribution of this study is to construct and investigate a conceptual model that focuses on the possible effect of moral disengagement of the leader on knowledge hiding by the followers. Also, by supporting the mediating role of trust in the leader, this research reveals that followers of leaders with high moral disengagement are more prone to indulge in the hiding of knowledge. Moreover, the moderating role of follower Machiavellianism, found in this study, provides an additional understanding that followers may vary in the degree to which they are sensitive to the leader’s influence.

Furthermore, the Weak Form Efficiency hypothesis is conducted on the overall scries of gold returns. The result obtained is that the Efficient Market Hypothsis of the Turkish gold market does neither hold for the scries of gold returns of the sub-periods nor for that of the overall series. The implications of this result for the current state of the Turkish gold market and the Istanbul Gold Exchange (IGE) arc discussed.
