With increasing trade among different countries The exchange rate fluctuations, consumption, inflation, and market portfolios are considered as major risk factors in financial markets. Hence this study aimed to examine the relationship between the exchange rate fluctuations and asset returns within a theoretical and empirical model, i.e. Consumption-based Capital Asset Pricing Model (CCAPM). To this end, a basic CCAPM was extended and imported consumables were included in Epstein and Zin’s recursive utility function. The research sample encompassed eight portfolios and monthly data from 2003 to 2014. The pricing model parameters were estimated using Euler's equations and Hansen and Singleton’s generalized method of moments (GMM). An estimation of the parameters of Euler's equations indicates the risk aversion and tolerance of economic factors, low elasticity of substitution for domestic consumables and imported consumables, and high elasticity of intertemporal substitution. In the next step, using Euler’s linearized equations as asset pricing model and Fama and Macbeth's two-step regression method, the effects of exchange rate risk premium, inflation, market efficiency, and consumption growth on return premium on assets were investigated. The results indicated the positive impact of the exchange rate risk premium, inflation, and market returns on the return premium on assets.

The current research sets out to identify and scrutinize the impact of the CEO’s perceptual biases in judgment and economic decision-making on the reporting quality of the firms listed on the Tehran Stock Exchange. Adopting a mixed method, the present study first seeks to detect the components and indices of CEO’s perceptual biases via critical appraisal and with the special participation of 10 accounting experts. Afterwards, the rec-ognized indices are set to undergo a Delphi analysis given the mean and the coefficient of agreement. The verified indices are then adapted to the ac-counting models and analyzed in the form of research hypotheses. The re-sults of qualitative analysis using Delphi method verify the reliability of 16 indices out of 22 ones. Regarding the quantitative analysis, the association between the indices of the CEO’s perceptual biases in judgment and econom-ic decision-making, and the primary proxies of financial reporting, namely reliability and competitiveness is tested. The findings reveal that the indices of the CEO’s perceptual biases in judgment and economic decision-making exert a significantly negative effect on financial reporting reliability and competitiveness.

Since the auditing profession is a process engaged in judgment activities, knowing the reasoning concepts to achieve a level of rationale in audit judgment is the theoretical and fundamental concept in this profession. In this regard, tactfulness is one of the decision-making components in an auditor's judgment that assigns a level of reasoning for making an intellectual decision and promotes the level of judgment quality in auditing. Accordingly, the purpose of this research is Auditors’ Wise Tactfulness in Professional Judgments by Total Interpretive Structural Modeling (TISM). The mixed-methods approach was used for the research in which, in the qualitative part, two experts population as panel members, and, in the quantitative part, 30 independent auditors as the statistical population participated. In the qualitative part, the meta-analysis approach was used to identify the themes related to wise tactfulness in professional judgment, and then, the basic themes selected were examined based on two criteria, concordance coefficient and average, in three rounds reciprocally until theoretical saturation was met. At this point, 14 themes were accepted among 20 basic themes. In the quantitative part, the themes accepted were coded first and then were distributed among the respective population, based on a matrix questionnaire, to identify the most effective trait of auditor's wise tactfulness in professional judgment using the Total Interpretive Structural Modeling approach. According to the results, the theme adherence to the principles of professional ethics as a basic theme of professional thinking was selected as the most influential trait of wise tactfulness.

Purpose: In the shadow of separation of the ownership from the control and the problem of representation arising from it in the modern business world, there is a need to pay attention to the CEOs' approaches toward takeover as decision makers in this area. Managerial entrenchment is considered as one of the consequences of separation of ownership from control that explains the difference between the incentives in the corporate management and causes a disturbance in internal control as a communication mechanism between the corporate's performance and the capital market. Paying attention to operant conditioning behavior like tournament incentives as a functional behavioral stimulus in CEOs reduces the profit-seeking attitudes among them and increases the effectiveness of the corporates' performance mechanisms in disclosing financial reporting. The purpose of this research is to study the relationship between the managerial entrenchment and the internal control weakness by operant conditioning behavior theory test. Design/methodology/approach: In this research, 95 companies listed in Tehran Stock Exchange were evaluated between  2013 and 2018. Considering the duality of internal control assessment, logistic regression in SPSS software was used in this research. Findings: Results of the research showed that there is positive and significant relationship between the managerial entrenchment and the internal control weakness. But there is a negative and significant relationship between the tournament incentive and the internal control weakness. Moreover, it was found that the negative relationship between the managerial entrenchment and the corporates' internal control is mediated by the tournament incentive. Originality/value: Considering that little attention has been paid to motivational issues of the CEOs under the representation theory over the past few years, the present research attempts to investigate managerial entrenchment approach with the effectiveness of internal controls through analysis of the operant conditioning behavior theory to provide more reliable experimental results for the investors and the shareholders.
