Interest rate plays an important role on financial market in any different sectors from real state to auto industry. An increase on interest rates will increase cost of borrowing money from banks, which reduces profitability. The proposed study of this paper investigates the relationship between bank interest rates on performance of stock exchange over the period 2001-2010. The proposed study categorizes interest rates into five different categories including short-term interest rate, special short-term rate, one-year, two-year, three-year, four-year and five-year terms. The results of performing regression analysis have confirmed that there are some positive and meaningful relationship between interest rate in all groups and performance of stock exchange.

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.

In this paper, we present an empirical investigation to measure the effects of intellectual capital using Maxwell model [Maxwell, J. C. (2003).

There are 11 sub-hypotheses in this survey based on Maxwell model and the results of this survey conclude that “Sharing the ideas” index maintains the highest rate of importance and “being detailed oriented” maintains the lowest rate of importance.
