The main motivation is the multidimensional feature of information quality concept with respect to the proxies and consequences of information quality along with the capabilities of DEA models in evaluating efficiency of decision-making units (DMUs: here the reporting entities) based on different inputs and outputs. In this regard, firstly the most important proxies and consequences of information quality are extracted from literature review and secondly considered as inputs and outputs of consequential two-stage NDEA model depending on their relationships with information quality concept and finally the information efficiency of reporting entities measured using simultaneously the proxies and consequences of information quality. The results revealed differences in DMUs' information efficiencies in different stages suggesting classic viewpoint deficiency of DEA models in evaluating DMUs' efficiency. Moreover, DMUs' efficiencies in first stage (proxies of information quality) are greater than their corresponding efficiencies in second stage (transforming proxies to consequences) and network efficiencies, resulted from optimization of all distinct stages, take an amount between first- and second-stage efficiencies. Among other results of the research in addition to providing a unique amount of network efficiency, is giving explanations for network and its components inefficiency, and identifying benchmarks for optimizations of inputs and outputs of each stage and overall network and setting a way to efficient frontier.

2 - The Effect of Personality Type and Professional ethics on Auditors' Ability to Detect Fraud Using the Theory of Planned Behavior by theRole of Professional Skepticism
Leyla Alizadegan Mahmoud SamadiLargani Mohsen ImeniAbstractThe purpose of this study was to investigate the effect of personality type and professional ethics on the ability of auditors' to detect financial reporting fraud using the theory of planned behavior with respect to the mediating role of professional skepticism MoreAbstractThe purpose of this study was to investigate the effect of personality type and professional ethics on the ability of auditors' to detect financial reporting fraud using the theory of planned behavior with respect to the mediating role of professional skepticism. The statistical population of the study includes auditors working in the auditing organization and auditing firms that are members of the Iranian Society of Certified Public Accountants. Using Morgan table, 302 people were selected as the research sample. The method of the present study is descriptive-survey and the tool used in the research is a questionnaire. The structural equation Modeling (SEM) was used to investigate the effect of variables and the partial least squares (PLS) approach was used to analyze the patterns. The results showed that the types of auditors' personality types, professional ethics and professional skepticism, have a positive and significant relationship directly on the auditors' ability to detect financial statements fraud. Also, personality type and professional ethics have an indirect and positive relationship with respect to the mediating role of professional skepticism on the detection of fraud in financial statements.According to the research findings, the more professional skeptics auditors are during the audit, the more willing they are to seek information about the signs of fraud and hence the greater their ability to detect fraud.

Risk management is one of the solutions for companies to deal with uncertainty in the business environment, which has an effective role in maintaining and improving efficiency and effectiveness and, consequently, improving company performance. In addition, risk management is an important factor in controlling costs and diversification product and, consequently, achieving competitive advantage that leads to better performance. However, presence of financially educated managers (financial literacy of managers) in the risk management process facilitates achieving competitive advantage and better performance. The aim of this study is to investigate the relationship between enterprise risk management and company performance with mediating role of competitive advantage and moderating role of financial literacy in manufacturing firms of Yazd industrial town. Data were collected using questionnaire and analyzed by structural equation modeling. The results of 220 completed questionnaires show that the relationship between competitive advantage and company performance is not statistically significant, but risk management has a positive and significant relationship with competitive advantage and company performance. Also, the relationship between financial literacy and competitive advantage is positive and significant. The mediating role of competitive advantage in the relationship between risk management and company performance is not confirmed, but the moderating role of financial literacy in the relationship between risk management and competitive advantage is accepted.

The political uncertainty index was calculated based on the approach of Becker et al. (2016) in terms of monetary, financial and exchange rate policy dimensions for the countries of Iran, China, the United States and the United Kingdom, and its relationship with the cryptocurrencies market ,Bitcoin, was evaluated. In this study, an attempt was made to evaluate this relationship using the financial accounting approach of cryptocurrencies assets, the most important of which is Bitcoin. The time period of this study was 2012-2021 based on the frequency of monthly data. The results obtained from this estimation of the general method of movement model indicated that the index of political uncertainty in China, America, England and Iran had a positive relationship with the monthly yield of cryptocurrencies and only the number of interruptions of the variable's influence was different. . Therefore, investors in the cryptocurrencies market can have a higher expected return by accepting the risk caused by political uncertainty and predicting the state of macroeconomic variables.

Research on corporate reputation has generally argued that reputational risk, or risk of reputation loss, stems from all company risks. When a risk drives a firm into a crisis, some stakeholders' interests may go unsatisfied, and the firm's corporate reputation may be eroded. The more effective the enterprise risk management system is, the fewer crises a company will face and the less risk there will be to lose its corporate reputation.The purpose of this study is to investigate the effect of the quality of enterprise risk management system and the characteristics of the audit committee on the reputation of companies listed on the Tehran Stock Exchange. The statistical population of the study is the companies listed on the Tehran Stock Exchange, of which 100 companies were selected as a sample. The results of Tobit regression model test showed that the quality of enterprise risk management system and the characteristics of the audit committee have a significant effect on the reputation of the companies under study.

Since the introduction of Markowitz's theory and even before that, the concept of optimal investment as a compromise between risk and return has been considered. During several decades after that, new definitions and dimensions of optimal criteria and especially risk have been proposed.In this article, an attempt has been made to present a model of liquidity risk using the concept of diversification in the form of Shannon's entropy and an econometric approach, an optimal portfolio of investments with the lowest risk and the highest return, in the form of a portfolio of 4 industrial groups of the Tehran Stock Exchange, including metal groups. Essentially, banks, oil products and metal ores, which have the highest market value of the Iranian stock market, should be provided.The statistical data of this research for selected industries include daily price index return and daily price gap return between 2015 and the end of 2019. To calculate the liquidity risk, using multivariate GARCH methods, the variance-covariance matrix of price index return and price gap, calculated and used in the presented model, and finally the optimal weight using coding in MATLAB software and using algorithm optimization method The genetics of non-excessive ranking of the second edition has been calculated for selected industries.The output results of the model show that the optimal weight of the groups with less variance in the optimal portfolio is higher. Besides, the effect of removing the concept of liquidity from the model leads to an increase in the weight of industries that have less liquidity, and along with the increase in risk, the return of the optimal portfolio also increases in this case. Also, by removing the limitation of Shannon's diversification index, the output results show that this limitation has almost no effect on the optimal weights (at least in this model).
