Tax avoidance is making use of legal loop holes to display an individual's financial situation as if it were lower than what it is in order to decrease the amount of income tax owed. Behavioral economics and taxation literature indicate that psychological factors can provide further insight on accountants' financial decisions. The literature claim that tax compliance can be influenced by an individual’s personality and beliefs. Therefore, in this research, the effects of psychological variables including Machiavellianism, emotional manipulation and moral foundations are examined on tax avoidance in accounting and finance professions. The aim of this study is to investigate the role of Machiavellianism and emotional manipulation as two negative attributes of human beings and moral foundations in tax avoidance in listed and unlisted firms. For this purpose, a sample consisting of 500 accountants and financial managers of listed and unlisted companies of Tehran stock exchange was selected. This study is an applied and descriptive survey. The hypotheses of the research have been analyzed by structural equation modeling using Lisrel software. The evidence of this study show that Machiavellianism has a positive and moral foundations have a negative effect on tax avoidance. But, this study doesn’t confirm any significant relation between emotional manipulation and tax avoidance. This paper also states that social and psychological variables  would  explain the tax avoidance phenomenon.

The Stock Exchange is a private sector savings and liquidity fund to fund long-term investment projects. The indicators of this market are influenced by several factors, one of which are economic variables. Banks are also one of the most important investors in the financial market. In this study, the effect of exchange rate, bank interest rate, liquidity and inflation rate on stock price index using time series data of 1978-1988 and using equation system model of four equations of the stock price index, inflation rate, profit rate Deposits, and facility interest rates were estimated using the three-stage least squares method. The results showed that the effect of the exchange rate, deposit interest rate and positive liquidity volume and the effect of inflation rate on stock price index was negative. Other equations have been estimated because of the relationship between the bank interest rate and inflation rate, and the results show that both deposit interest rate and facility interest rate have a positive relationship with the inflation rate

Strategic management accounting, including systems and processes in the modern era, is characterized by changes in the competitive environment that, Can be achieved through the participation of companies in the management accounting system, Assist financial managers to make decisions in the value chain and develop green accounting functions.

Banked based financial sector of Iran leads us to focus on the banking industry and its components. One of the important aspects of this industry is its coupling structure. In this paper, we have analyzed the collective behavior of Iran banking sector by Random Matrix Approach (RMT). This technique is useful for splitting the information part of the correlation matrix from the random region. This research confirms good compliance with random matrix predictions. By removing the market mode of the system the average of the banking cross-correlation matrix changes. Then, by calculation of the participation ratio, node participation ratio and relative participation ratios of these banks, it is shown that the collective behavior of the system is so fragile. Also, by applying local and global perturbations on the banking sector, it is shown that this system is very sensitive to the global perturbation and the mean value of cross-correlations decreases rapidly that means some banks have crucial effects in the market.
