The mutual relationship between monetary and fiscal policies and value at risk is one of the most important topics in the financial economics literature and accounts for the vast majority of empirical studies. Therefore, the main objective of this paper is to investigate the effects of monetary and fiscal policies on conditional value at risk in the financial sectors of the stock exchange, bank and insurance during the years 1995-2017. For this purpose, by quantile regression method and in the form of Adrian and Brunnermeier approach, the conditional value at risk of these three financial sectors is estimated and then by using the seemingly unrelated regression equation approach in panel data evaluated the effect of liquidity money variables. The interest rate on facility payments, the real exchange rate, the government's budget deficit, real GDP growth, and the degree of economic openness are subject to conditional risk. The results of the model estimation indicate the significance of the effect of liquidity money, interest rate on facility payments and real exchange rate variables on conditional value at risk in each of three relevant equations, and real GDP growth variable in the model, Exposure to the conditional value at risk of the insurance sector has a negative and significant effect. Also, the degree of openness of the economy in any of the three estimated equations has no significant effect on the conditional value at risk. 

The purpose of this study is to investigate the impacts of external and internal organizational factors of the privatization process on the management accounting practices and the impact of these changes on the financial performance of listed companies on Tehran Stock Exchange that more than 51% of the companies' shares have been transferred to the private sector.

To collect data, questionnaire survey and companies financial statements were adopted and to test the hypothesis Structural equation modeling using Smart PLS software. The findings of the study show that external and internal organizational factors in the privatization process, have a significant impact on the management accounting practices that these changes effects on the financial performance of companies. The result is that in the privatization process, the external and internal organizational factors and contradiction of the incompatibility of these factors with the human factor provide the conditions for management accounting practices changes that effect on the financial performance of companies. The results of the current study could be useful for the effectiveness of management accounting changes and their impact on the financial performance of companies in the integration and acquisition process in developing countries.

This study aims to investigate the relationship between technology use factors based on the developed unified theory of acceptance and use of technology (DUTAUT) with auditors' ethical behavior. This research is applied and descriptive-correlational and its population include various auditors of Iran, 164 of whom are selected using simple random sampling. Structural equations and Smart PLS software analysis are also used to test the hypotheses. The findings show that there is a positive and significant relationship between technology use factors based on DUTAUT, including motivational components, effort expectancy, performance expectancy, and social effects, and ethical behavior of auditors. Other findings show that there is a positive and significant relationship between motivation (64%), effort expectancy (31%), and social effects (43%) with auditors' ethical behavior at the 95% confidence level. Given that the use of technology is expanding and is in line with current social needs and increases the level of ethical behavior in auditors, it is necessary to pay more attention to it in order to increase the ethical climate in this profession.

This study aimed to investigate the relationship between voluntary disclosure and earnings management and financial performance during the life cycle of the listed companies in Tehran Stock Exchange. The statistical population of the study included all listed companies in Tehran Stock Exchange since 2013-2018. In this study, earnings management, the financial performance of the companies (including return on equity, returns on assets, Tobin Q ratio, economic value-added, and refined economic value added) were the dependent variables, and the level of voluntary disclosure was the independent variable and the life cycle of the company was considered as the moderating variable. Also, in order to test the research hypotheses, a linear multivariate regression model using combined data was used. The results showed that earnings management and financial performance indicators have a significant relationship with voluntary disclosure over the life cycle. Accordingly, an increase in the level of voluntary disclosure increased the company's performance. Also, the results of the study indicated that the company's life cycle mediates the relationship between the level of voluntary disclosure and the company's performance.

The present study was conducted with the aim of designing a model for evaluating the performance of financial units in petrochemical industry. This exploratory practical study carried out based on the descriptive-analytical method and all data were gathered via two separate processes as interview and literature review. The statistical population included professional and academic experts in the field of human resources (HR) to answer qualitative questions by targeted sampling for experts. According to the experts’ opinion, in order to identify effective factors, the Grounded Theory method and Interpretive Structural Method (ISM) were applied for evaluation of method and structural equations, respectively. After reviewing all the 67 indicators of financial performance that were extracted from theoretical foundations and previous research, 48 indicators have been approved by Delphi Roxab Group and then were selected. Finally, content factor analysis showed that all 48 indicators are significant enough. The novelty of this research compared to the similar ones raised from identifying the factors related to "production and procurement" and so "marketing" of the understudy organization that have not been evaluated in the previous studies.
