Accordingly, the present study aims at investigating the link between related-party transactions and earnings management in the firms listed on the Tehran Stock Exchange. In addition, it seeks to answer whether political connections moderate this association. To this end, the present study adopts related-party transactions as the independent variable, political connections as the moderating variable, and discretionary accruals as the dependent variable. The statistical population of the research consists of 86 firms listed on the Tehran Stock Exchange during the years 2015-2019. The research hypotheses were tested using a multivariate regression model based on panel data. The findings reveal that related-party transactions are significantly correlated with earnings management. Also, the membership of political figures on the firms’ boards intensifies the relationship between related-party transactions and earnings management. Manuscript profile -

In this regard, deciding on financial leverage (capital structure) is one of the most effective ways to achieve these goals. On the other hand, the value of the company's stock and the expected return of shareholders are also affected by the stock liquidity factor. Lower stock liquidity is expected to lead to relatively greater use of debt. In addition, information asymmetry plays a key role in how managers make decisions about how to finance and determine the company's capital structure. Therefore, this paper investigates the effect of information asymmetry on the relationship between stock liquidity and excess leverage in the Tehran Stock Exchange during 2012 to 2018 using the information of 133 selected companies. The results show that there is a negative and significant relationship between stock liquidity and excess leverage and information asymmetry moderates this relationship and reduces its tensity. In fact, in companies with high information asymmetry, due to the lack of simultaneous access to information and the existence of information asymmetry, the negative impact of liquidity on excess leverage is less tensity and less.

Variety in policies, such as government policies and economic policies affect the stock market and cause stock price changes. The predicting stock price movement on a daily basis due to the non-linear and chaotic stock price movements is a difficult task. There are several ways for predicting in stock market. Artificial intelligence techniques have been widely used to predict data with nonlinear and chaotic structure. One of these techniques is neural network. If neural network is trained correctly, then it has minimum error in predicting.
