Objectives: In management accounting literature, budget is the foundation of management control process in most organizations. Therefore, budgeting and management accounting information systems are control tools that depend on each other as the two sides of a scale. Design/methodology/approach: The research method used is an exploratory survey. All managers of Shiraz municipality constitute the statistical population of the present study. Sampling was not used in this research. In order to test the hypotheses of the research, SPSS software version 24 and "one-sample t-test " and "one-way analysis of variance" tests were used. Results: The findings of the research indicate that the usage of the management accounting system in the budgeting system by the managers of different levels of Shiraz municipality is more than mean, but it is still far away. Also, the findings indicate that there is no great difference between the usage of these managers at different management levels from the management accounting information system in the budgeting system. Based on these results, the status of the management accounting system in the budgeting system should be improved in Shiraz municipality. Originality/value: The review of the studies conducted in Iran indicates that no research has been observed that proves the role of accounting system information in municipalities in their budgeting system so far. Therefore, from this point of view, this study is innovative and needed to be implemented for the first time in one of the metropolitan municipalities of Iran.

Objective: This study explores the determination of audit fees (AF) using Support Vector Regression (SVR) among companies listed on the Iranian stock market from 2017 to 2021. It investigates the relationship between financial variables like financial leverage (DA), current assets ratio (CA), quick ratio (QUICK), ASSETS, current ratio to current liabilities (CR), and long-term debt (DE), with AF as the target. Methodology: Data from 60 listed companies during this period, totaling 279 year-observations, are employed. SVR models are trained on this dataset using Google Colab. Results: The SVR model achieves a 90.5% R2 value and a 3.7 Mean Squared Error (MSE) on training data, indicating high explained variance and reasonable error levels. However, on new data, the model's performance diminishes, with an R2 of 67% and an MSE of 8.1, implying reduced accuracy and intermediate predictive accuracy. Innovation: This study advances the understanding of AF determination using SVR, highlighting the importance of considering various financial variables.

Objectives: The present study aims to examine the impact of a company's regulatory mechanisms on the enhancement of earnings information content in the Iranian capital market. Design/methodology/approach: A sample of 142 firms listed on the Tehran Stock Exchange from 2013 to 2022 was chosen using a systematic exclusion model. The research hypothesis was then tested through multiple linear regression tests based on panel data. The profit reaction coefficient and the company's supervisory mechanism, as indicated by the owner's internal control criteria, were used to measure the information content of profits. Results: The study found a direct and significant correlation between the company's supervisory mechanism and the information content of earnings. Improving the quality of the monitoring mechanism led to an increase in the information content of profits. Innovation: This study offers valuable insights for company managers and stakeholders in the capital market. By effectively utilizing regulatory mechanisms, the level of information content of profits in the market can be enhanced.

Objectives: The present study aims to investigate the impact of debt, taxation and financial crisis on earnings management . Design/methodology/approach: This research is applied and from the methodological dimension is causal correlation. The statistical population of this study was all companies listed in Tehran Stock Exchange and using systematic deletion sampling method, 138 companies were selected as the sample and were studied during the 8-year period between 2015 and 2022. Results: Four hypotheses were proposed for the present study. The results of testing the research hypotheses showed that financial crisis and corporate tax had a direct impact on the company's earnings management, but debt did not affect the company's earnings management. Originality/value: The current research provided evidence that dealing with the financial crisis and paying taxes are the main factors in increasing earnings management in companies.

Objectives: The purpose of this study is to investigate the role of company ownership in investment efficiency, focusing on business strategy. Design/methodology/approach: This research is applied, with a causal correlation methodology. The statistical population of the study included all firms listed on the Tehran Stock Exchange. Using a systematic sampling method, 135 companies were selected as the sample and examined over an 8-year period from 2015 to 2022. Three types of institutional ownership—management, family ownership—were considered. Results: The results of testing the research hypotheses indicated that institutional ownership, as well as family ownership, have a direct and significant relationship with the investment efficiency of the company. However, managerial ownership showed no relationship with the efficiency of the company's investment. The interaction of family ownership with business strategy impacted investment efficiency. However, the interaction of institutional ownership and managerial ownership with business strategy did not affect the efficiency of the company's investment. Innovation: The current research provides evidence that the types of company ownership have an impact on investment efficiency and emphasizes that the role of business strategy cannot be overlooked.

Objectives: The purpose of this research is to examine the relationship between the board of directors' compensation and earnings management in companies listed on the Tehran Stock Exchange. The moderating effects of corporate governance and social responsibility are also examined. Design/methodology/approach: To measure corporate governance, criteria such as ownership concentration, institutional investors, and the presence of internal auditors are utilized. Earnings management is measured using Jones' modified model (1991), and accountability is assessed by using a checklist. The statistical population for this research includes 147 firms over 8 years from 2012 to 2019. Research hypotheses are tested using multiple regressions based on the panel data method. Results: The findings indicate a positive and significant relationship between earnings management and Board compensation. Additionally, the company’s social responsibility, ownership concentration, institutional investors, and internal auditors influence the relationship between earnings management and board compensation. Innovation: This research examines the relationship between earnings management and board compensation, while also considering the moderating role of corporate governance and social responsibility in firms listed on the Tehran Stock Exchange.
