This study examines the relationships between levels of job satisfaction, perceived supervisory actions, and intentions of Iranian trainee accountants to remain in their related firms. This study also examines differences between trainee accountants of Audit Organization (AO) and public accounting firms relative to their perceptions of the existence of the supervisory actions and of their job satisfaction. Data was collected using a survey questionnaire in 2007. Findings suggest that perceived supervisory actions (comprising aspects of leadership and mentoring, working conditions, and work assignments) are significantly and positively related to job satisfaction. Likewise, findings of the study indicate that there are positive relationships between job satisfaction and intentions to remain in the firm. Finally, significant differences were found between Audit Organization and public accounting firms relative to all the elements of supervisory actions and job satisfaction, with accountants at public accounting firms reporting higher levels of each variable

This study provides some evidence about the characteristics of firms whose managers use discretionary accruals to smooth income. First, firms are classified into two categories of smoothers and non-smoothers then their characteristics of having opportunity and motivation to smooth income are examined through six hypotheses. Consequently, based on mean comparison of two independent groups and logistic regression analysis, the study provides evidence that income have had a weaker performance leading to a higher motivation compared with non income smoothers in Tehran stock exchange. Moreover they have more opportunity to smooth income because of having larger absolute discretionary accruals.

This study attempts to predict future stock returns by return on owner’s equity ratio (ROE) namely, earning to equity book value ratio and its variability both in company level and in portfolio level. Calculation of owner’s equity is based on Ohlson’s (1989) model and clean surplus relation (CRS). The research of the statistical population includes 130 of companies listed in Tehran Stock Exchange during 1379 to 1384. The research results show that there is a significant relationship between ROE and future stock return. But, the explanatory power of the ROE is stronger and more significant in portfolio level than company level. Also, the results indicate existence of a significant relation between variability of the time series ROE of a stock and the future return of that stock.

The primary purpose of this study is to investigate the relevance of free float of the accepted companies in Tehran stock exchange with their rate of return. The data utilized in this research are based upon data of 55 companies between 2004 to 2006 years. In this research, we used of free float as independent variable and the stock returns as dependent variable. For the test & the research hypotheses, T-statistic and linear regression is used. The findings of this study indicate that this is a significant relationship between free float stocks and stock returns. This relationship varies for different level of free floats and among different industries.

One of the recent reforms in countries budgeting system is movement to performance-based budgeting that focuses on government's performance appraisal. But available evidences imply, this reform is slightly done. This problem creates many questions about why a few countries implement performance-based budgeting completely and what governments require in order to assure complete implementation. In this research, shah model has been used, in order to identify barriers of implementing performance-based budgeting in Tehran University. This model considers nine factors affecting performance-based budgeting implementation that are as following: Performance Evaluation Ability, Technical Ability, Personnel Ability, Organizational Authority, Legal Authority, Procedural Authority, Political Acceptance, Managerial Acceptance and Incentive Acceptance In current research, existing status of these factors was surveyed by polling university managers and factors having bad status, were identified as a barrier of implementing performance-based budgeting in Tehran University.

In this paper, we will intend to introduce Degree of Economic Leverage and it's usage as one of the new techniques in explanation Beta coefficient and identification the systematic risk and profit planning equipment in leverage theoretical conceptual as well. Meanwhile, we will consider and analyze it through experimental testing for increasing its justification explanatory potency. The Degree of Economic Leverage is defined as the percentage change in the firm's sales resulting from a unit percentage change attributable to an exogenous economic disturbance. After theoretical conceptual studies by using regression analysis and Pearson correlation testing, the research objective that is the inverse and meaningful relation between interest rate and firm's sales is not acceptable but confirmed by hypothesis testing that there is no relation between Degree of Economic Leverage and market return and expected return, but Degree of Economic Leverage explanted expected return better than Degree of Operational Leverage and Degree of Financial Leverage. Degree of Operational Leverage will expellant market return better than the two other leverages. Also there is a meaningful difference between measure of the Beta calculating by DEL and the BETA computing by CAPM, DCAPM.
