In this paper, we present an empirical investigation to measure the effects of privatization on some selected firms listed on Tehran Stock Exchange. The proposed study of this paper selects eleven relatively big sized Iranian firms whose structures were privatized prior year 2011. The main hypothesis of this survey studies whether there is a meaningful relationship between ownership structure and enterprise value of privatized firms. We collect the necessary information before and after privatization process completed and using a regression model examined the main hypothesis as well as five sub-hypotheses. The results of the survey indicate that the number of major shareholders has been reduced after privatization process accomplished, the number of shares had no impact on firms’ values. In addition, non-board members’ duty had not impact on firms’ value before and after privatization process, institutional investors did not play important role before and after privatization process, and separations played important role on firms’ value before and after privatization occurred.

Most organizations benefit from ethical leadership and try to establish ethical rules and regulations in their working environment. This paper proposes an empirical investigation to learn the relationship between ethical leadership and organization learning. The proposed study designs a questionnaire based on Northouse model [Northouse, P. G. (2012). Leadership: Theory and practice. SAGE Publications, Incorporated.] and distributes it among all 108 managers in province of Charmahal-Bakhtiari located in west part of Iran and, using Pearson correlation, we examine different hypotheses. Cronbach alpha is equal to 0.86, which is well above the minimum desirable level of 0.70. The results of our study indicate that all five components of ethical leadership including respect, serve, justice, honesty and socialization have positive and meaningful relationship with organizational learning.
