Independence of the Board, duality role of the CEO, institutional shareholders, state ownership, existence of the internal audit, audit opinion, changing of the auditor and the transaction with related parties are considered as corporate governance mechanisms proxies. In addition, firm size and the financial leverage are entered to the model as control variables. The final sample of analysis includes 110 firms for a period of 6 years from 2007 to 2012 and the multiple regression method based on panel data was used to test the proposed research hypotheses. The results indicate that despite the existence of negative relationship of board independence, state ownership, audit opinion, auditor change and leverage have negative impact with the tax gap; internal audit and size have positive impact on the tax gap. In addition, there is no significant relationship among the duality role of CEO, institutional shareholders and transactions of related parties with the tax gap.This paper examines the relationship between corporate governance mechanisms and tax gap.

Auditing is an efficient way to limit the authority of the directors in contractual relationship. In this paper, we investigate fluctuations and changes of short term and long term audit fees. For this purpose, the data of listed companies in Tehran Stock Exchange for the periods 2007 to 2012 were extracted. To test the hypotheses, the cross-sectional regression of the combined data was used. The results show that the stickiness of audit fees not follow a clear trend. In other words, it will be changed in a multi-year period and in short periods of time (usually annually) changes in the fee will not be visible. Also, the results show that the audit firm will not change their fee in the early year but, in subsequent years, adjust their fees according to the understanding of the client. Finally, the results indicate that auditor change resulted in audit fees closer to the standard model.Agency problems were created between managers and shareholders as a result of conflict of interest.

This model explores the existence of asymmetric earnings response by using financial variables such as size, book-to-market ratio, leverage, stock return volatility, unexpected earnings and abnormal returns. Result of implementing pool data regression on 1140 firm-year observations from 2005 to 2012 indicated lack of asymmetric earnings timeliness and according to Ball, Kothari and Valeri (2013) model.

Overconfidence is an important feature of managers who are optimism about future earnings and cash flows and have a positive view of potential risk and return. Hence, we are going to investigate the effect of managers' overconfidence on dividend policy. We study 56 companies listed in Tehran Stock Exchange in the period of 2007 to 2012 to test the hypothesis. The results show that there is a significant and negative relation between managers' overconfidence and dividend policy; in other words they have lower dividend payout. We also demonstrate that an overconfident manager perceives the current operating cash flow as a stronger predictor of future operating cash flow so and increases the dividend payout. In addition regardless of whether the manager is rational or overconfident, a manager in a higher-growth firm pays a smaller dividend than a similar manager in a lower-growth firm.The characteristic of managers' personality is a key factor in their dividend policy.

Accordingly, the present paper adopts a part of the framework derived from the decision-making literature about psychology and applies it to auditing. As Shanteau proposes, expert decision-makers possess fourteen psychological characteristics. The importance of each characteristic is assessed employing the experimental method for 65 auditors from an auditing organization in four phases including planning, test of transactions, testing the details of balances, and issuing the audit report. Hypothesis-testing was made by means of correlation test, Friedman non-parametric test, as well as Spearman correlation matrix. The results revealed that all of the fourteen characteristics are important across all the four phases of the auditing; nevertheless, the degree of significance in each phase was not the same so that in the first phase the most important characteristics are Responsibility and Selectivity, and in the second phase they are distinctions between Relevant-Irrelevant Information and Adaptability. The Perceptual/Attention characteristic in the third phase of auditing comes to be the most significant and in the final phase of auditing. Automaticity has the highest degree of importance.The purpose of this study is to identify the psychological characteristics contributing to expertise which consequently have an effect on auditor judgment.

Candidate of Accounting, Imam Khomeini University, IranJournal Article20131111This paper studies the disclosure quality in family firms in time period of 2007 to 2012, and aims to answer the question that whether the family factor will affect the disclosure quality. TSE’s disclosure scores and discretionary accruals are used for measuring disclosure quality. The family firms in this article are the firms that family members have significant influence on them. One of the factors for significant influence in firms is board membership. Board membership is measured by dividing 1 by numbers of board of directors plus one. Our results show that family firms don’t have any advantage in disclosure quality. In other words, the family factor does not affect disclosure quality.This paper studies the disclosure quality in family firms in time period of 2007 to 2012, and aims to answer the question that whether the family factor will affect the disclosure quality.
