This paper presents an empirical investigation to study the effects of electronic banking devices such as automated telling machines (ATM), Point of sales (POS) and Pin Pad on profitability and market share in Iranian banking industry. The population of this study considers the information of 16 banks, five governmental and eleven private, over the period 2007-2012. Using two regression techniques, the study has detected that while Pin Pad may influence on return of assets positively, ATM and POS may not have any meaningful impact on profitability. Moreover, in our survey, none of technological facilities had a meaningful impact on market share but there was a positive and meaningful relationship between bank size and market share.
This paper presents an empirical investigation to study the effects of free cash flow, share diversification and capital structure on Tobin-Q in selected firms on Tehran Stock Exchange. The population of the survey includes 520 firms listed on this exchange until year 2012 and the survey uses a sample of 105 firms, randomly. The study uses the models originally developed by Palepu (1985) [Palepu, K. (1985). Diversification strategy, profit performance and the entropy measure. Strategic Management Journal, 6(3), 239-255.] to measure the effects of different factors on Tobin Q. The study has indicated that while capital structure and free cash flow influence positively on Tobin Q, diversification has maintained a negative and meaningful relationship with Tobin Q.

This paper presents an empirical investigation to study the relationship between financial structure on profitability and price volatility of banks’ shares, which are operating in Iran. The proposed study considers the information of 21 Iranian banks over the period 2006-2012.

This paper characterizes the stockholders overreaction thorough return and price mean reverting behavior in specified ten major industry groups in Tehran Stock Exchange (TSE). For investigation of mean reversion presence, we use corporate firms from ten specified industry groups traded on the Tehran Stock Exchange and using a random walk with drift model with data over the period 2009-2013 period and recursive estimation in stability diagnostics test. The primary objective of this paper is to investigate mean reversion phenomenon in ten major industries including maximum number of real and nonstrategic investors with two different methods on quarterly return and monthly price time series. The results indicate that mean reversion occurred in the returns of these industry group. In addition, we use two major Unit Root Tests as complementary and final analysis. Out results also indicate that mean reversion takes place, significantly in eight industry groups and price time series in two industry groups follow a random walk process.
In this paper, we address the stockholder overreaction and mean reversion in specified major industry groups in Tehran Stock Exchange (TSE). This paper investigates this issue with panel data analysis and with particular attention to the Box-Jenkins Approach for stationary diagnosis with appropriate order and modeling stock prices with regard to specific industries. The study processes modeling of panels where stationary and mean reversion takes place in complementary analysis. The sampling intervals are explored monthly within the past few years. The results reveal that mean reversion presence in three industry group stock prices and industry stock prices would not behave in certain pattern.
This paper performs an investigation on the effects of seven variables including growth domestic product, financial deepening, inflation rate, dependency burden, the number of bank’s branches, inflation rates given/charged on bank deposit. The study has been performed on one of Iranian banks named Sina Bank over the period 2006-2011. The implementation of individual regression analysis has detected a positive and meaningful relationship between growth domestic product, financial deepening, inflation rate and the number of branches on one side and bank deposit on the other side. In addition, the study has confirmed a negative and meaningful relationship between two variables of dependency burden as well as interest charged on bank’s clients and bank deposit. However, the result of our survey does not indicate that there was any relationship between interest rate paid to customers and bank deposit.
The purpose of this study is to analyze the relationship between operational risk and accounting conservatism. The criterion used for operational risk in this study is asset volatility and for accounting conservatism, we use Ball and Shivakumar (2005) model [Ball, R., & Shivakumar, L. (2005). Earnings quality in UK private firms: comparative loss recognition timeliness. Journal of Accounting and Economics, 39(1), 83-128.], which analyzes accounting from balance sheet sight. The statistical society used in this study is taken from 15 banks in Tehran Stock Exchange over the period 2006-2012. The research result demonstrates that there was a negative relationship between operational risk and accounting conservatism. In other words, there is a significant negative relationship between operational risk and accounting conservatism. Hence, the results suggest that with an increase (decrease) in operational risk, accounting conservatism decreases (increases).
This study examines the impact of corporate governance structure and free cash flow on over-investment on 121 firms listed in Tehran Stock Exchange over the period 2008-2011. To measure over-investment, free cash flow and corporate governance variables based on available information reported on financial statements are gathered and using cross section regression method, different hypotheses of the survey are examined. The results indicate that among corporate governance mechanisms investigated in survey, there is a significant relationship between percentage of non-executive directors and ownership concentration with over-investment. However, there was no meaningful relationship among controlling shareholders and duality with over-investment. Furthermore, a significant relationship between free cash flow and over-investment has been found.
One of the primary duties of the depositary banks is to protect themselves against any possibility of bankruptcy. This requires the identification and measurement of risks, including default risk, which is important given the nature of the activities of banks. This paper presents an empirical investigation to study the relationship between default probability and some financial figures including operating cash flow, liabilities and return of equities. The proposed study of this paper uses historical data of twenty-two firms listed on Tehran Stock Exchange over the period 2008-2012. Default probability as the dependent variable is measured by the method developed by Moody’s KMV Company. The study uses linear regression model to examine the relationship between default probability and some independent variables. The results of the present study suggest that there were some reverse relationship between operating cash flow per share, return on equities and default probability. In addition, there was a direct relationship between log facilities and default probability. However, there was not any relationship between net sales and default probability.
