The main aim of this study is modeling and determining hierarchy of the criteria of real earning management on the prediction of the bankruptcy of the companies listed in Tehran Stock Exchange. The required data was collected from financial statements of 81 companies, during 1386-1396. In this study real earnings management model developed by Dechow et al. (1998) similar to those in Roychowdhury (2006), and the risk of a bankruptcy Altman's criteria (1983) were used. The analysis was attempted via multivariate regression of pooled data algorithm. The results showed the relationship among the flow of abnormal operating cash costs, discretionary abnormal production costs, discretionary abnormal costs and probability of bankruptcy occurrence had positive significant, negative significant and non-significant effect, respectively. In addition, increasing (decreasing) of flow of abnormal operating cash costs resulted in increasing (decreasing) probability of the bankruptcy occurrence. Increasing (decreasing) of discretionary abnormal production costs led to decreasing (increasing) probability of the bankruptcy occurrence.

The book-to-market ratio (B/M) is a noisy measure of expected stock returns because it also varies with expected cashflows evolution of B/M, in terms of past changes in book equity and price, contains independent information about expected cashflows that can be used to improve estimates of expected returns. This study examines the impact of the components of the book to market ratio on the explanatory power of stock returns. To this end, a sample of 185 companies listed in Tehran Stock Exchange during 1384 to 1393 were studied. To examine the explanatory power of stock returns by components of the B/M ratio, Fama and Macbeth regression (1973) and portfolio analysis approach are used. The results show that this improvement comes mainly from the change in price, against the results of other countries, and not from the change in book equity

The present study has been conducted to design a comprehensive model to identify and rate the risks of Islamic securities. For this purpose, the Islamic financial field was initially identified by the formation of an expert team and the internal relations were analyzed between parameters of relevant factors to risks of Islamic securities at two main steps. The first step was to identify the related risks and factors to Islamic securities which were carried out by a decision-making team including 20 experts in the field of capital market after reviewing the literature and the background of the research using a fuzzy Delphi method. Some factors including asset and publisher, intermediate institution (broker), market and price and credit and economic status were assumed as the identified factors by the experts at first step. These factors were ranked by taking their internal relationships into consideration using DEMATEL technique at the second step. According to implementation of DEMATEL method, the research findings showed that the asset and publisher was a variable which influenced variables of intermediate institution, market and price and credit and economic status at the highest level and it was as a powerful influential factor and also variable of credit and financial status was considered as a strong penetrating variable. In other words, the variable of asset and publisher affects market and price and credit and economic status.

The purpose of this study is to investigate the effective factors on the implementation of the personal Banking model in Refah Kargaran Bank based on Osterwalder's Business Ontology. In this study, the relationship between the three components of the customer, financial management, infrastructure management and the proposed value of providing personal banking products and services of Refah Kargaran Bank was examined. By identifying the effective factors in the implementation these patterns based on Osterwalder and Pigneur (2004), Using the descriptive – correlation and path analysis model, the result of this study shows that there is a significant relationship between customer components, financial management and the proposed value in the personal banking business model. A significant relationship between the infrastructure management and the proposed value component was not approved

The main goal of investors is to maximize wealth. Wealth depends on two factors: risk and returns. For this reason, it is vital for shareholders to predict these two factors. The purpose of the present research is to use the five-factor model of Fama & French to predict stock return in offensive and defensive share. For this reason, 105 companies were selected through the systematic disposal method for the period of seven years, from 2008-2016. Also, in this research the beta coefficient has been used to identify offensive and defensive shares. After the formation of portfolio and factors calculation, the cross-sectional regression was used to analyze the data. After analyzing classical hypotheses and co-Linearity test, the final model for each of the offensive and defensive shares were estimated. The results of the research show that value factor and size as a redundant variables but the profitability factor have. The profitability factor has a negative effect on the additional return of defensive shares and do not have effect on the additional returns of the shares offensive. The investment factor has a positive effect on the additional returns of the shares offensive and do not have effect on the additional returns of the defensive shares.

The measurement of corporate efficiency has been always noticed by researchers in the evaluation of performance due to its importance. This paper has investigated the relationship between some of important working capital management policies with firm efficiency. Initially, the efficiency of the listed companies listed in Tehran Stock Exchange (TSE) in Iran during period (2011-16) was calculated using Data Envelop Analysis (DEA) as one of effective tools by taking Window Analysis approach (length of panel: 2, 3, and 4 years), then the efficiency trend in these firms was examined in terms of increase or decrease of efficiency over the time and finally corporate efficiency was identified as well. Besides, the relationship among working capital management and the efficiency of companies was explored with Generalized Method of Moments-GMM. The findings indicate that average collection period negatively affects efficiency at significant level and while the variables of sale growth and current ratios positively affect the firm efficiency

Investment efficiency is achieved when the company only invests in projects with positive present value. The aim of this study was to evaluate the impact of financial policies on investment efficiency in the company is listed on the Tehran Stock Exchange. The main hypothesis in this study is: there is a significant relationship between Financial politics and investment efficiency. What distinguishes this research from other research in the field of investment efficiency is variable financing policy using the model McKnight et al. (2009) and Brukman (2009) that the debt ratio, financial leverage and cash dividends have used is measured and to measure the efficiency of investment have used Richardson (2006). The sample has been selected using systematic elimination and restricting the number of variables 75 years (1390-1395). The hypotheses were tested and analyzed using regression model and control variables taking into account the value of the company, ROA, ROE and net working capital using panel data regression technique. The results suggest that financial policies have significant impact on investment efficiency. In addition, financial policies and investment efficiency have different effects on companies with different values. The users of financial statements including investors are recommended to choose companies with higher debt ratio and financial leverage and less dividend

Considering the influence of supervision's power and managers' decision-making authority, the aim of the study is to investigate the relationship between the managers' ability and the firms' performances. The method of the study is operational on the base of purpose and is naturally correlative. Financial information of 163 firms listed in Tehran Stock Exchange was extracted as a statistical sample using Systematic Elimination and then it was investigated in the period of 2007-2017 (1386-1396). Statistical analysis of data was done by using Eviews with confidence level of 95%; and in order to test the hypothesis, the statistical method of Panel Data and Multi-Variable Linear Regression were used. The findings show that there is a direct significant relationship between management ability and the firms' financial performance (Returns on Assets, Tobin's Q ratio). Also, the authority power of the directors is correlated with managers' ability, it increases firms' Tobin's Q ratio and ROA. Moreover, according to the third hypothesis, the level of supervision has a positive relationship between management ability and Returns on Assets and Tobin's Q ratio.
