The purpose of this study was to investigate the role of corporate governance in corporate tax planning.The features of the used corporate governance include the size of board of directors, the size of off duty board, the stability of the position of CEO and financial specialty of the board. Tax planning is measured by GAAP and cash ETR (Effective Tax Rate).In order to test the research hypotheses, financial information of 54 firms from 2009 to 2013 was used and multiple regression analysis was employed as the statistics method. The results show that corporate planning mostly exists in the firms with fewer board members. In addition, the more off duty board members in a firm and the more stable the position of the CEO, the more corporate tax planning. The findings of the research do not show a clear effect of the financial specialty of the board on tax planning. The findings, however, indicate that the firms with higher ROA have more tax planning but financiall everage has no effect on tax planning. The effect of firm size on tax planning is not clear either.

This paper seeks to empirically test the effect of off-balance sheet financing and financial constraints on cost stickiness.In addition, it deals with the effect of financial leverage, the size of the firm, earnings quality, earning ratio on the effect of off-balance sheet financing and financial constraints on cost stickiness.Cost stickiness means that the ratio of sale decrease is less than that of cost in creaseat the time of increase in sales. To perform the analysis, the data from 60 companies listed between the years 2008 to 2013 were used. To test the hypotheses, the multiple regression using the combined data is used. The experimental evidence shows the behavior of cost stickiness and the effect of financing costs and financial constraints on the strength of cost stickiness.The findings indicate a strong positive correlation between the severity of stickiness with off-balance sheet financing and financial constraints on all the companies studied, regardless of the type of industry

Decision making with regard to the dividend is an important topic because this is influenced by various factors such as economic factors. One of the economic factorsis the company's life cycle. According to the life-cycle theory, companies in different stages of the life cycle show specific behaviors financially and economically. It means that institutions and companies follow specific policy according to stage of their economic life. Thus, the present study investigates the relationship between cash dividends paid and investment at the company's life cycle in listed companies in Tehran Stock Exchange. Accordingly, the research hypotheses were tested using the mix data regression in Tehran stock exchange with regard to the related data from 2003 to 2012. Among all attended companies, 680 companies were selected as the statistical sample. The findings show that there is a significant direct relationship between the cash dividend and investment,but this relationship differs in various stages of the company's life cycle.

This study aimed to investigate the effect of control mechanisms of corporate governance on cash holdings in companies listed in Tehran Stock Exchange. Given the development of companies and the introduction of representation theory and increased duties and authorities of the board, a question has been raised more seriously how managers who are not actually the owners of the company pursue the interests of shareholders.Considering unlimited powers delegated by the owners to the board, attention given to corporate governance has increased dramatically. Corporate governance is a set of control mechanisms within the company and outside the company that makes an appropriate balance between the equity and the needs and authority of the board. Finally, these mechanisms make the shareholders, fund suppliers and other interested groups sure that investment will be back with reasonable profits and their interests will be considered. To test the hypotheses, a sample of companies listed inTehran Stock Exchange during 2005 to 2012 has been selected. To see the effect of corporate governance on the level of cash holdings, multivariate regression model was used. For this purpose, 90 companies were chosen ad analyzed for the study. 9 criteria were used to calculate the corporate governance and the effect of the 9 criteria was tested using the software of Stata11. The results showed that the corporate governance has a positive effecton cash holdings. Among the 9 criteria, the dichotomy duties of the President of the Board & CEO, the percentage of non-responsibility, the opinion of the auditor, the change of the auditor and the independency of audit organization had no significant effect on the level of cash holdings. The rate of benefits received, however, had a negative effect while the size of Board of Directors, the percentage of institutional ownership and reliance on debt had a positive effect.

One of the most important issues in financial distress prediction is the selection of predicting variables. The present research in contrast to previous works provides a new approach to feature selection using the classification of financial ratios based on financial semantics and a combination of statistical methods with meta-heuristic algorithms.
To this end, 34 financial ratios based on the audited financial statements are collected for distressed manufacturing companies according to paragraph 141 of Iran Trade Law and healthy companies listed in Tehran stock exchange (TSE) sampled randomly between 2001 and 2011 for one and two years prior to distress. Then, using t-test and genetic algorithm respectively, best ratios from the primary feature set are selected and support vector machine is applied to predict financial distress. The experimental results showed that the proposed HARC method outperforms logistic regression and Altman model significantly for one and two years prior to distress in predicting financial distress.

The purpose of this research is to investigate the effect of cash flow uncertainty on investment-dividends sensitivity in the companies listed in Tehran Stock Exchange (TSE). In this research, cash flow uncertainty is measured by cash flow shortfall and cash flow volatility and the effects of each of these two measures on relationship between dividends and investment has been investigated separately. The research hypotheses were tested based on a sample including 96 companies for 8 year period between 2003-2011using multiple regression model and pooled data method. The result of hypothesis testing indicated that there is a significant negative relationship between dividends and investment. The cash flow shortfall and cash flow volatility reduce investment-dividends sensitivity. In other words, cash flow uncertainty reduces the extremity of negative relationship between investment and dividends.

The aim of this study is to investigate the effect of social responsibility on corporate value by moderating role of advertising intensity in the companies listed in Tehran Stock Exchange. The study combined data from 74 companies for the period of 2008 to 2013 and analyzed the pooled data. This research is a correlation study whose hypotheses are tested using combined regression with pooled data through Eviews7 software. The results show that social responsibility has a significant effect on corporate value with the moderating role of advertising intensity. It means that in creasing advertising intensity, the effect of social responsibility on corporate value increases. Technical and institutional aspects of social responsibility also have positive and significant effects on these companie's value while the technical dimension had a stronger effect than institutional dimension. To control the effects of other factors on the model, control variables such as the size and leverage of the model are used.
